Fern-grass

Many grasses flower in May. Also this Fern-grass (Catapodium rigida) that shows off the little whitish stamens that cover its spikelets, as if somebody sprinkled them with sugar.

Grasses (Poaceae) are anemochores, they need the wind to disperse their pollen. Not that easy to take advantage of the wind if you are small and low on the ground.

Apparently, Fern-grass manages well, it flourishes notwithstanding its small size. It grows everywhere in arid spots where there is not much other vegetation. Like a limestone meadow on dry soil, between the gravel on a path, or, as here above, on a stone wall.

It does not really look like a fern.

More like a toothbrush. Its spikelets are in two rows both turned towards one side.

For a plant so tiny it is rather conspicuous, even between more colourful Trefoils you cannot not see it.

Two Sow-thistles

Especially in somewhat ruderalized surroundings and not far from human activity you can find Sow-thistles. Those big 'Thistles' enjoyed the rain from past weeks to grow really big. The two species here below are easy to find. They look much alike.

Here Prickly Sow-thistle (Sonchus asper) on the side of a small road. (Take 'prickly' with a grain of salt.)

And here Perennial Sow-thistle (Sonchus oleraceus) on the edge of a field. (Also take 'perennial' with a grain of salt, it is mostly annual.) Both species have yellow flowers in open, slightly chaotic, panicles.

Maybe the inflorescences of Prickly Sow-thistle are a bit less dense, and the flowers of a slightly darker yellow...

 
...than those of Perennial Sow-thistle). But the difference is not really big.
For a safe bet, look at the leaves.

Perennial Sow-thistle has deeply incised leaves often glaucous and not shiny. Where the leaf is attached to the stem there is on both sides a pointed auricle.

The leaves of Prickly Sow-thistle are prickly, of course, but they are nothing compared to those of real thistles. They are brilliant on the upper surface, and green with sometimes a tinge of red. There are also auricles, and they are rounded.

And this spring rosette? Difficult to see, notwithstanding its bluish colour it is a Prickly Sow-thistle.

Annual Pea

Because of lockdown we have to stay near our homes. In Dordogne there are still many corners with interesting wildflowers, and you risk, even when you respect lockdown rules, to come upon some surprising plants. Like this little yellow pea, an Annual Pea (Lathyrus annuus) that grows on the edge of a field just a bit more than 100 m from a house.

Its leaves look like the grass blades on which it attaches itself with its curling vines. If there are no flowers it is surely difficult to find it.

This plant made already big pods covered with very fine hairs. A fair chance it will be back next year. It was not evident to find its name, it is not yet in the 'flore de Dordogne'. There are only very few mentions for this species in Dordogne, so it is very rare and it is really extraordinary to stumble upon it.

Some questions need to be asked. Why is Annual Pea so rare? It is considered as a Mediterranean plant, is it enlarging its area towards the North because spring temperatures are on the rise? Or has it been here since long and has become rare because of (let's say) destruction of habitat? Or has it been always rare?

To verify.

Common Dogwood

At this moment it is in flower and the rain that fell so much those first days of May does not matter.

Common Dogwood (Cornus sanguinea) is a bush you can find in many places. It can grow nearly everywhere on limestone soil, and often also elsewhere.

It makes beautiful bunches of white flowers, every flower with four petals, four stamens and a style.

At the end of summer it makes black berries.

Sometimes it covers with its branches and leaves that easily turn red piles of stones, old walls and forgotten corners in abandoned grounds.

Its leaves show typical curved, deep lying veins, they are easy to recognize.
