Polycarpon tetraphyllum - Four-leaved Allseed
Four-leaved Allseed is extremely rare in mainland Cornwall and is known from only three sites. In the allotments near Wearde Quay (SX45I) it is almost certainly an introduction. Still plentiful here in 1984, it was rather scarce in 1987 when last recorded. At Cadgwith on the Lizard (SW71H) it is considered to be native. Thought to have become extinct in 1934, it was refound in 1983 by A.J. Byfield and is still to be found here (1998, P.A. Gainey). A new site was discovered on St. Michael's Mount in 1996 (SW52E, C.N. French). This Nationally Rare, Red Data Book species is common on the Isles of Scilly, growing in bulb fields, on walls and pavements, on road verges, and in gardens.
