The twining – plant horror

It’s a miracle I’m here to bring you this post. I’ll tell you what happened. I was out as usual, with my camera, looking for new things coming into bloom. I was lucky – or I thought I was, hah! – to see some beautiful purple poppies at the side of a narrow country road near my village, on a bank above a stream. So I was snapping away…

…thinking that these were probably Papaver somniferum, the opium poppy. I was wondering how they got there, inching forward, leaning over and I slipped, my head went down…and I don’t remember much after. Then I must have woken up, wet, my feet still in the stream, looking above me at a dark tangle of spiny branches, thankful I was still clutching my camera to my chest.

‘Who’re you, and what the  hell  are you doing there?’ A voice came from above.  I scrambled up the steep side of the stream through the thorns, replying  ‘It’s OK,  I’m just a bit muddy, that’s all’.

‘You may be in the mud, but we’re all in the shit here, so you’re lucky’

‘What do you mean?’ I looked up. The man was  wearing what looked like usual gardening gear, but instead of a spade or a garden basket he was carrying a large billhook in one hand and a knife in the other. ‘You’re expecting trouble?’ I tried to joke. ‘The usual’, he shrugged.

I looked at the ground around – I was sure – I knew – that when I fell the ground was verdant, the luxuriant growth of a warm wet spring. Now I saw dry earth from which emerged sprigs of blasted brown twigs. No colour, but here and there a small pale plant with pale flowers, in the nearest of which I saw a pale spider lurking.

Sedum ochroleucon

‘What’s that?’ – a stupid question, the only form I could give to my puzzlement. And stupid because I pointed at it. As soon as I did, a shoot whipped out from the brush above the stream and a tendril began to wind round my finger.

‘Don’t move!’ The man leapt towards me and slashed violently with his billhook. ‘We should get out of here while we can – the greens are all against us now, aren’t they?’ As I looked, the pale flowers were shrinking, and the shoot telescoped in on itself.

The man shoved me in the back. ‘Come this way, I’ve got a garden over there, we should be OK for a bit. But watch out for the cucumbers’

‘What?’  I’ve been nervous of many things, but never of that vegetable.

‘The squirting cucumbers.  They’ve got so they’re that strong, the seeds can rip you to shreds if you brush against them.’  I looked at the ground again as we walked away and as I’d expect in a dampish place there were lots of that low-growing plant, whose fruits I knew developed a huge pressure to squirt out and distribute their seeds.

Bang! One went off, and I saw holes appear in my new friend’s trousers. ‘Be a bit more careful, won’t you’ he shouted over his shoulder. We reached a stone wall, and he unhooked a gate and waved me to get in, quick.

‘Here I can keep the jungle at bay for a spell’ he waved his blades and looked around.

‘What do you mean? What the hell’s going on with Mother Nature?’

‘Mother Nature my arse! Evil Witch Nature more like. Look, if you’ve been asleep for years or something, I’ll explain. We never knew we were so lucky, and now it’s all begun going backwards. You used to cut a plant – now they cut you. We used to eat plants, now they’re all going poisonous. ‘ He pointed at a patch of green, and I saw  Euphorbia exigua, toxic like all spurges, growing through.

‘They’re getting everywhere. And you plant a lettuce, and what do you get?’ He pointed at a row which started as normal-looking salads, but ended in tall spiky plants. ’Would you eat that?’ He thrust a leaf at me – it had spines round the edges and a fearsome array along the vein.

Lactuca serriola

Lactuca serriola

An offensive salad, a lettuce with armour. It was Lactuca serriola, the supposed ancestor of cultivated salads. ‘They’re all turning back to what they were, they’ve had enough of us, we’ll be  hunter-gatherers next year, I tell you. Look, I’d better get you back to my house, the wind’ll get up tonight and then the wind-blown seeds’ll  flay you alive.’

He opened the gate and peered around. ‘Follow me!’

I was still getting my head round the fact that Nature, which I’d always believed was healthy, beneficent, reliable, could turn so nasty.

‘Watch out! Get over here quick!’ I should have leapt to him, but I turned round.  Out of the compost bin a dead brown surge was lifting the lid, falling, turning green and coming my way.

It twined round me, I could feel it gripping, tightening, rooting me down, I couldn’t move. I flailed with my arms, my only free parts.

‘Hold still or you’ll get cut!’ He was hacking with the billhook, slicing expertly with the knife and I concentrated on staying still till a limb was freed. ‘I told you it’s all going backwards- the dead stuff comes alive and grows all over you – then it’ll shrink and squeeze you till it’s the size of a seedling – and what’ll be left of you then?’ He pushed me to the gate.

It was like being in the world of antimatter – full of anti-Nature, stuffed with antiplants with antigrowth. I’d lost my bearings.   I’d have to trust my new guide.

We left the garden and began to trot down a path. I followed his hunched, zig-zag gait, as if he were running under enemy fire. The wind was getting up, carrying dust, and spiky dry leaves and bits of twig which stung my face and hands. My guide pointed to his right. ’Watch out for them – they’ve got a hundred times bigger, and if they get you it’s like being hit by a nail-studded baseball bat.’

I looked across and saw great round spiny balls, like the heads of the ‘rolling thistle’ Eryngium campestre, careering past us in the gathering storm. We ran faster, but the ground seemed sticky and greasy – some gummy plant I suppose – and a colossal ball of spikes hit my friend and bowled him over. I was sure he was injured and skidded over to help him up. ‘I’m OK – bullet-proof vest under the shirt. But you’ll have had it if one hits you’.

Killer seeds in the air!

Running on the path was like running on treacle. My friend was stumbling.  It was getting darker. The wind was rising and the saw-toothed seeds were about to blast our skins off. We were passing a bank of pointy little blooms as red as blood.

Trifolium purpureum

Trifolium purpureum

Hopeless. If Mother Nature wasn’t there, who was? I thought of Flora, the Roman goddess whose devotees threw lupins, vetches and chickpeas at the crowds at her festival, the Floralia. The blood-red flowers! Purple clover! As good as a vetch or a lupin, surely! I grabbed handfuls and flung them in the face of the wind, yelling ‘Flora! Flora!’  The wind increased and seemed to lift me up, and either inside or outside my head I heard the motto of the goddess resound: ‘Use life’s beauty as it blooms!’.

I was back on the country road by the poppies – but it was night. Yes, I know that this story reads like a dream, a nightmare you wake up from. And here I am back in my usual world, not in antiplant world. But just tell me, would you: if it was just a dream, how did those pictures get onto my camera?

If this story has even mildly entertained you, have a look at what the professionals can do in the video below. I declare an interest – it’s the project of my brilliant son-in-law, Si Stratton.

Something’s Got a Hold of my Root: Broomrape (Orobanche)

This is a sort of opener for a series on telling similar plants apart, but I also wanted to say something about these remarkable flowers.

Orobanche gracilis - slender broomrape. Its host,the legume Dorycnium, is in the background

This was the first of these striking inflorescences I saw – pointed out to me by CL, who must be developing a botanist’s eye in order to be able to live with me. It’s Orobanche gracilis, slender broomrape, and like all plants in this genus it’s a parasite, living entirely on the water and nutrients of its host plant , which for this species can be any legume (Fabaceae family – anything resembling peas and beans).  The plants are distant relatives of snapdragons and toadflaxes, which you can see in the shape of the flower and the form of the inflorescence.

With  its distinctive red markings inside the flower, it’s beautiful in a rather weird way , partly due to the absence of green – the plant has no  chlorophyll at all – and partly because I can’t bring myself to like a plant that preys completely on something else. Its human equivalent must be the thief, the pimp, the drug dealer – I’ll come back to that.

A dry stem of broomrape - O. picridis or O. minor?

A dry stem of broomrape – O. picridis or O. minor?

Within a week or two, I’d found another broomrape, this time in the sand dunes, but all that remained was a dried flower stalk. I’ve since found another, very similar but equally dry, in the next village to mine. So, some detective work needed. I’ve narrowed  the main possibilities for these to two:  Orobanche minor, or O. picridis, since both were tall and slim, with small flowers, and near what looked like a Picris – a species of oxtongue with a small dandelion-like flower. They could be one of each – and O. minor is said to be found near the sea and also parasitises composites like Picris, as well as legumes.

This leads me to the difficulty of identifying broomrapes in general – they’re mostly in shades of yellow through to pink, most have a single spike of whitish flowers, and to make matters worse, most are variable in appearance depending on soil, location and host. But there is one main clue to note: they are usually pretty close to their host plant. This helped me identify the next broomrape I found, on the sauveplaine. There were a couple of small colonies, both next to, even growing through the leaves of their host plant, Eryngium campestre or field eryngo.

This is Orobanche amethystea, which parasitises a variety of plants, mostly umbellifers like Eryngium (members of the family now named Apiaceae).

What about the strange names for these blooms, with their echoes of violence? Broomrape comes from the Latin name for one species parasitic on broom – O. rapum-genistae – rapum (the Latin word for turnip) in this case signifying the root-swelling where the parasite has taken hold. Orobanche comes from orobus (vetch) and ancho (strangle).

I wondered how the life-cycle of Orobanche could work, given that it has to  find a host,  and that cross-pollination must be as rare as the plants. They often self-pollinate, and the flowering heads can each then produce  100,000 tiny seeds. These are the seeds from one of the dried plants – each seed is only a tenth of a millimetre across.

Orobanche and seeds

Orobanche and seeds

The seeds can lie dormant in the soil for years, until stimulated by chemicals from the roots of a living host plant (for more on the  social life of plants, see my post here).  The seed then germinates, sending a small rootlet towards its host root and boring in to the vascular tissue.  This creates a bulge or tuber on the root, from which the flower will eventually arise – after which the broomrape dies. While they are rare in Britain, and often protected, they are a significant problem for agriculture in other areas, principally dry regions such as North Africa and the Near East. Orobanche crenata parasitises broad beans, and it’s estimated that Egyptian farmers lose up to 40% of their crops to this predation. The tiny seeds are easily spread by animals and farm machinery, and the problems there, and in Morocco and Algeria, are increasing.  Farmers will have to pick the flowers before they set seed, and clean tractor tyres to contain the spread.

How to find the jazz in all that? Well, I’ve just been reading  So What, the superb biography of Miles Davis by John Szwed (who wrote the equally brilliant bio of Sun Ra, Space is the Place). Davis comes over as little more than a parasite in his relationships with non-musicians, especially with women.  And a thief and a pimp at times. He was so insecure, so dependent, so demanding, and without them he was cocaine-addled and dormant.  But there’s the life, and there’s the work, and my admiration for and love of the man’s music is undimmed by his portrayal.  Here’s something from just one of the revolutions Miles wrought in music, often, as here, with the help of his friend Gil Evans: the Birth of the Cool, and Moon Dreams.

Coming up next: They’re as alike as two peas – hang on, they are two peas

Been there, dune that

I’d like to take you to the other patch I’ve chosen in which I’m going to try to list all the species of plants I find. Other patch? Yes, the first was in the previous post.  That was in the hills, this is by the sea, and already the comparison is showing me a lot about each habitat.  Here we are at Marseillan-plage:

The dunes of Marseillan-plage, looking west (promenade up on the left)

The town of Marseillan is a very old port on the Étang de Thau, founded in the 6th century BCE by the Greeks; facing the Mediterranean its neighbour Marseillan-plage is – there are no other words for it – a brash new tourist resort, which has invested a great deal of money in the last year to become, well, even brasher. But it has a botanical jewel in its narrow system of dunes.

Jewel? Doesn’t it look just like a patch of dried-out weeds?  Look closer. There are at least two separate main ecosystems here, separated by the promenade between the town and the harbour: the dunes nearest the sea are the least stable, blown by wind and spray, and only a few species can take the conditions: Euphorbia paralias (sea spurge) which I blogged here, Elytrigia juncea (sand couch grass), and Ammophila arenaria (marram grass) are examples.  The Euphorbia can store water in its stems and fleshy leaves.

Elytrigia juncea - sand couch grass - Chiendent des sables

These are the shifting sands – dunes vives in French – pegged down by rows of fencing made of chestnut stakes. These are in place all along the coast, after the damage of a great storm in November 1982 awakened the authorities to the gradual erosion of the coastline by the prevailing east to west currents.

On the town side of the promenade and sheltered by it from the worst of the wind and salt spray, a much more diverse flora has established itself. Although the sand is infiltrated by seawater, there is a layer of fresh water within the sand which lies on top of the salt because it’s less dense, and a plant with roots deep enough to reach this layer can survive. Even so, the plants here in the arrière-dunes show even stronger adaptations to drought than on the sauveplaine. For example, this clump of Paronychia argentea has a low, dense growth habit, and refective silvery bracts round the flowers, creating its own shade underneath.

Many dune plants are covered in a thick downy coat of hairs, which both reflect heat and reduce evaporation, such as this Sea medick (Medicago marina), which is rarely seen away from the coast.

Others have leaves reduced to slender leaflets, such as Centaurea aspera (rough starthistle) and Anthemis maritimus.

One unexpected discovery was the dry stem of this broomrape. These plants are completely parasitic on other plants, and can often be identified by spotting the host plant nearby.  In this case the yellow composite is a clue to its probable identity as Orobanche minor (common broomrape), and this species is often found near the sea. The grass in the picture is Lagurus ovatus : hare’s tail or bunny-tail grass, or Queue-de-lièvre.

I’ve found a couple of other broomrapes recently: they’re stunning flowers and I’ll write a post about them soon.

At the foot of the landward side of the fixed dunes, just before the houses begin, the terrain is more fixed, the water is closer to the surface and perhaps some organic matter can accumulate to enrich the sand – at any rate, some plants here resemble those of further inland, or even those of gardens. For example, a stout Lavatera arborea (tree mallow) would grace any front yard, and the wild leeks (Allium ampeloprasum) are the same as those on the sauveplaine.

The Marseillan patch study is now up to 24 species – I’ll work on a list which I’ll set up on another page on the blog here, and keep updated. The close study of two very different areas is fascinating, and it’s showing me that the dune season is much more compressed, with some flowering seasons over before those in the hills have really started. The grasses in the two places are completely different – I’m trying to get a grip on identifying these.  And over the summer I expect to see the real dune specialists which flower most of the year, such as Anthemis, and others yet to be discovered. But the greatest wonder of the dunes is that very different habitats are found only metres apart, and so in ten minutes you can have a good lesson in ecology. I’ll be suggesting this as an important asset to the municipality – there’s been a lot of redevelopment in the town in the last year and I’d hate for this area, which is like a wild park in the centre of town, to be disturbed to lay drainage pipes or to build ice-cream stands. The rest of Marseillan-plage is concrete, with imported palm trees.

Here’s some music from a region I imagine to be as dry and sandy as the dunes. It’s from the album Jama Ko, by Bassekou Kouyate and Ngoni Ba, recorded in Bamako in Mali in 2012, and something I like very much indeed.  This track, Poye 2, also features the bluesman Taj Mahal, a longtime fan of Kouyate.
