I think the sub species status has now been dropped and the other sub species promoted to species status. Called Chalk Fragrant-orchid in Stace III.
using 'Orchids of the British Isles' Foley & Clarke, 2005 also calls it Chalk Fragrant-orchid: G. conopsea (Syn. G conopsea subsp c...) where I got a little confused.
