Beihe ‘te 19 (1923) 58; Fedde Repert. Beihefte 59

This species has been found only in Costa Rica where 
it grows on trees in forests up to 2600 meters altitude.

Osmogtossum convallarioides Schlechter in Fedde Re- 
pert. Beihefte 19 (1928) 148. 
This species forms with Odontoglossum Meertoni 
Lindl. and O. pulchellum Batem. ex Lindl. a complex 
group of plants. All three species are similar in habit. 
However, there are floral differences which readily keep 
them apart. This species differs from O. HM gertonii in 
that the broader lateral sepals are almost free instead of 
being urited almost to the apex as in that species, and 
the lip is distinctly constricted below the middle, a char- 
acter lacking in O. Mgertoni. The column ot O. conval- 
larioides is almost without apical lobules, whereas the 
column of O. Ngertonii is deeply 8-lobed with the lobes 
fringed. Odontoglossum convallarioides differs trom O. 
pulchellum not only in the smaller flowers but also in 
the column which is not conspicuously lobulate and in 
the lip which is flat and concave instead of being strongly 
arcuate-deflexed as in that species. 
This species is rare in Mexico and Guatemala, but 
common in Costa Rica, where it occurs as an epiphyte 
on trees in forests usually at high elevations up to 2700 
meters altitude.
