Huperzia selago - Fir Clubmoss
Fir Clubmoss is very rare in Cornwall and is most frequent on the Lizard. It is susceptible to the effects of fire and that may be the cause of its recent disappearance from Traboe Cross (SW72F). Although one plant was still present in 1995, (P.A. Gainey), it could not be found when last searched for in 1998. On the Lizard it can still be seen in short, wet heath on Gwendreath Common NNR (SW71J) and on Goonhilly Downs NNR (SW71E). However, it has not been seen on Kilmar Tor (SX27) since 1978 though one plant may still survive on Rough Tor (SX18K, 1988, P.A.Gainey) and new records were made at Treskilling Pit, near St. Austell (SX05I, 1998, I.J.Bennallick) and in a disused quarry near Trewarmett (SX08T, 1998, I.J.Bennallick). In both cases only one plant was found.
