This species was poorly understood before the
revision by Crundwell & Nyholm (1964); older records are
given only where determinations of old specimens have been
revised more recently.
Apparently rare in Cornwall. Revision of specimens
in Dec. 2001 revealed that most DTH records were errors (the
plants having tubers that are too large, often >200 µm, and commonly dull
brownish rather than bright yellow). Only the following record
appears to be correct: on humic sandy soil by edge of lake,
partly bare of higher plants, unshaded, NW. edge of Dozmary
Pool, SX 193745 (SW17X), 17 Oct. 1996, DTH 96-478 (DTH).
Revision of specimens from BBSUK, E and NMW by DTH revealed
many other errors; two correct records have notes as follows:
soil beside ditch, heath N. of Tretoil; clover field on
Prospidnick Hill, N. of Helston. As noted above, no voucher
has been located to support the records from Retire Common
(SX06B, 1961 and 1963, JAP) which include the first record in
vc2; these are mapped but need
All gatherings have tubers. Not seen c.fr.
Prospidnick Hill material is male.
