CUBA: PROVINCE OF PINAR DEL Rio, vicinity of Venales, on 
hillside, N. L. & E. G. Britton, no. 7540, September 17, 1910; 
Wright 3307 in Hb. Gray. 
I have been unable to refer this plant satisfactorily to any 
described species of Habenaria., It is similar in habit to H. 
repens Nutt., but from that it differs markedly in the form of 
the petals and labellum. The cuspidate or mucronate sepals are 
similar to H. repens. It may be the form of H. tricuspis Rich. 
to which Grisebach referred in his Catalogus Plantarum Cubensium 
characterized by reduced anterior divisions of the petals, an 
assumption which leads to the belief that H. tricuspis may not 
be referable to the synonymy of H. repens after all, and that it 
is a variable plant, characterized by variations in the relative 
lengths of the lip divisions and by petals with variously reduced 
anterior segments. However this may be, I find in my herbarium 
a specimen of Н. repens from Georgia accompanied by the fol- 
lowing note: "Compared with Wright 3305 (sub nom. tricuspis) 
and Wright 3309 (sub nom. tricuspis Rich. near H. radicans 
Griseb.) at British Museum and found to be like them.” The 
specimen in question is quite distinct from H. Brittonae. In the 
study of the type material of H. tricuspis Rich. the conclusions 
arrived at, as indicated in Orchidaceae I V, were that it was con- 
specific with H. repens, a conclusion which is borne out by 
Kranzlin in Orchidacearum Genera et Species, and by Cogniaux 
in Urban's Symbolae Antillanae, although neither author states 
that he has seen Richard's type. 
Wright's 3305 and 3309 preserved in the Gray Herbarium of 
Harvard University, both labelled H. tricuspis var., are referable 
to H. repens, as they have the characteristic perianth divisions 
of that species. Wright's 3307, on the other hand, preserved 
in the same collection, is characterized by lips and petals similar 
to those of the plants from Venales. H. tricuspis as described by
