Habenaria diffusa A. Richard & Galeotti in Ann. 
Sci. Nat. ser. 8, 3 (1845) 28. 
The specific name is misleading and rests on an error 
in observation. Lindley described the petals as being tri- 
fid, hence the petals and labellum would constitute a 
nine-lobed corolla. In 1910 the type was restudied and 
the petals were found to be bipartite. 
Habenaria novemfida is also a native of Mexico, 
Guatemala and Salvador.

This is a widespread species ranging, without appar- 
ent change of character, from Florida to the West Indies, 
Mexico, and Guatemala. 
Habenaria Selerorum Schlitr., a native of Guate- 
mala, is a very close ally of H.odontopetala and may prove 
to be inseparable from it. H.Jimenezu Schitr., a native 
of Costa Rica, resembles very closely H.odontopetala, 
and should be regarded with suspicion until more material 
has been studied.

This species ranges from the state of San Luis Potosi 
in Mexico through Guatemala to Honduras. ‘The sepals 
are 1.5 cm. long and the divisions of the labellum may 
exceed 2.5 em. in length. The extraordinarily large flow- 
ers are white and make this species one of the most showy 
of the genus. It differs from the closely related HZ. mac-
