Judging trom the type description of Odontoglossum 
Ghiesbreghtianum supplemented by a photograph and a 
drawing of a flower (presumably from the type) in the 
Herbarium of the Muséum d’ Histoire Naturelle in Paris, 
it appears to be certain that this concept is referable to 
Oncidium tigrinum. Moreover, the fact that the lip pro- 
jects at almost a right angle to the column marks the 
species as a member of the genus Oncidium rather than 
of Odontoglossum. 
It does not appear to us to be advisable to follow 
Krinzlin (in Engler Das Pflanzenreich IV. 50, pt. 2 (Heft 
80) (1922) 234) in referring Oncidium splendidum A. Rich. 
ex Duchartre to Oncidium tigrinum. The almost sessile 
lip with different calli of the former species seems to be 
diagnostic, even though the two concepts appear to be 
closely allied. Oncidium splendidum has been reduced to 
varietal status, as O. tigrinum var. splendidum, by J.D. 
Hooker in Bot. Mag. 97 (1871) t. 5878.
