On my walk ... the rock samphire
Walking the paths by the sea even though it is getting late in the season it is still possible to see this 'iconic' flower of the seaside, rock samphire [ Crithmum maritimum] . It is one of those plants that seems capable of growing in the most extreme conditions and, indeed, only grows in extreme conditions, on rocks, walls, shingle and barren conditions exposed to the weather and sea spray. Rock samphire looks as though it is not quite in flower even when it is! The flowers are cream or green and are umbrella shaped which is quite typical of the carrot family to which it belongs. Unlike other carrots however the leaves are very fleshy and this helps it store moisture and so thrive where other flowers cannot.

There is also a golden samphire which is totally unrelated. This was once a popular food plant and was harvested and ...

ReplyDeleteThe articles in this thread provide a comprehensive overview of cryptogams, a diverse group of organisms characterised by their reproduction through spores rather than seeds or flowers, earning them the name "hidden marriage." They explore three main categories: Pteridophytes, which include vascular plants like ferns and horsetails known for their ancient lineage and ecological roles in soil stabilisation; Bryophytes, encompassing non-vascular plants such as mosses and liverworts, highlighting their importance in water retention and as pioneering colonisers; and Thallophytes, focusing on lichens (symbiotic fusions of fungi and algae/cyanobacteria), fungi (nature's primary decomposers and recyclers), and slime moulds (unique protists vital for nutrient cycling), all of which play crucial, often unseen, roles in supporting Earth's ecosystems and offering insights into the planet's evolutionary history.
