Isoetes histrix - Land Quillwort
A Red Data Book species, Land Quillwort is restricted, on mainland Britain, to the Lizard Peninsula. It is most abundant within half a mile of the sea, typically within erosion pans and on well trodden tracks on cliff-tops from Kynance Cove north to Mullion, especially within SW61S. It has been recorded more sparsely at suitable sites further inland such as at Kynance Gate (SW61W). Here it is found around outcropts of Serpentine where the soil is thin and vegetation sparse. Though found almost entirely on the serpentine, there is one site on the schist, namely Caerthillian valley (SW61W). In 1984 the plant was found in SW72 by M.G.B. Hughes. It has now been refound, the plants growing within a shallow outcrop of serpentine north west of Traboe Cross (SW72F, 1998, I.J. Bennallick).
