We have only seen a single flower, beginning to wither. It was of 
a yellow colour, not unlike in size and colour that of Miltonia 
stellata, from which it differs in having an elevated plate passing 
down the middle, narrower sepals, and a flat panduriform lip. It 
is No. 1595 of Messrs. Loddiges’ Catalogue.” 
Odontoglossum heterosepalum (Rchb.f.) Garay, stat nov. 
Basionym: Odontoglossum angustatum var. heterosepa- 
lum Rchb.f. in Linnaea 22: 850, 1850. 
An examination of the holotype, FUNCK & SCHLIM 1242! 
(W) collected in Merida convinces me that Reichenbach’s var- 
iety constitutes a distinct species. It is hard to understand why 
Reichenbach called this a variety of O. angustatum Lindl. 
While his statement added to the description explains a famil- 
iarity with the excessive natural variation observable within 
species of Odontoglossum, the variation pattern of O. hetero- 
sepalum cannot be accommodated within the pattern of varia- 
tion of the southern O. angustatum.
