Distribution and Occurrence.
Thread Rush is widely distributed in both the New and the Old World and seems to be spreading in Britain and now occurring here. The specimen on the LEFT was found after stormy conditions in the Spring had eased and this shore was exposed again. It was hanging on by a thread! Most of the other Thread Rushes in the area were intact in a slightly clayey bank which had not been broken up. Perhaps if sections like this drifted away from the site they might root elsewhere. So far, we have looked in many such suitable habitats but strangely it has not be re-located yet!
This picture is reproduced courtesy of WikiMedia Commons (many thanks!) and shows the characteristic features of a plant in the way that only a good sketch can do. (I wish my wife would start to produce such work!!!)
The painting is by Jacob Sturm from 1792
It effectively shows the detail we have shown in our photographs apart from the ribbing on the stem which is characteristic of the species.
‘a’ shows the reddish coloured roots with flowering stems arising from it in precise order.
‘d’ refers to the structure of the flower with 6 Tepals (combined petals/sepals and the remnants of a stigma withering on top of the ripening fruit.
‘e’ is a mature capsule with its little topknot holding it all together.
