There are two sheets of this species in the Le Mans Herbarium, 
kindly lent for determination, but the specimens are all so fragmentary 
that I have been obliged to remove, moisten, and analyse many flowers 
to determine approximately the form, etc. of their organs. No habitat 
is attached to either sheet, one of which bears a ticket inscribed no. 226, 
fleur bleu violette; gousse longue.
