OPHRYDEE. 305 
observe that there is a number of plants resembling H. monorchis in habit, 
but differing in having a short and, usually, inflated spur. In some respects 
it might be advisable to combine all these plants under one generic name ; 
and I formerly thought of adopting this plan; but upon a more mature 
consideration of the numerous unpublished species with which I have since 
become acquainted, I have been obliged to abandon the opinion. This 
point settled, the next question naturally was, are they to be placed 
in Platanthera; with which they may easily be made to combine techni- 
cally. There is, however, a certain peculiarity of appearance in the cal- 
carate Herminia which is unfavourable to their combination with Pla- 
tanthera; and, upon the whole, I have at last made up my mind that the 
best course to take is to adopt Blume's genus Peristylus for all the plants 
that would be Herminia if they had not a spur, confining the latter genus 
to the absolutely spurless species. 
Chamorchis of Richard has undoubtedly a folded rostellum ; but at the 
same time the plicature exists in so very inconsiderable a degree, and the 
plant agrees so nearly with true Herminia in habit, that I am not willing 
to consider it distinct.
