Taraxacum hamiferum Dahlst., a dandelion
Morphologically at the interface between T. hamatum and T. subhamatum, and also closely related to T. quadrans (all three of which microspecies are now considered either present or possibly so in Fermanagh), the re-determination by Richards in 2008 of three of Hackney's 1975 BEL vouchers to T. hamiferum doubles the number of Irish VCs in which it is known to occur! Previously this dandelion, which is quite frequent and widespread in Britain, was known only from Westmeath (H23) in the Irish Midlands (Dandelion Handbook).
Two of Richards' determinations of the Fermanagh specimens are more definite than the third. Firstly, there is voucher H5029, collected 28 March 1975 along with T. hamatum and T. nordstedii and the immature but possible specimen of T. subhamatum on a roadside verge at Slawin Td, near the S shoreline of Lower Lough Erne. The second definite determination was a specimen collected 30 March 1975 on a flat, grassy roadside verge near Tattycam Lough, between Lisnaskea and Rosslea, BEL accession number H5048. A second voucher from this latter site, H5049 was considered by A.J. Richards on the specimen, "probably T. hamiferum".
Sadly, again the Fermanagh records do not feature in the Field Handbook hectad map which contains 24 squares with Irish records, the majority of them in the Midlands west of Dublin (Richards 2021).
