Oncidium chrysopyramis Reichenbach filius & Warsce-

cidium (1855) 29, no. 97; Veitch Man. Orch. PIl., pt. 
8 (1892) Oncidium 25; Krinzlin in Engler Pflanzenr.

Judging from drawings of the habit and floral analyses 
of Oncidium chrysopyramis from the Reichenbach Her- 
barium, supplemented by the descriptions, it does not 
seem reasonable to separate this concept from the earlier 
O. pyramidale. The latter species appears to differ from 
O. chrysopyramis in having a longer panicle with the 
lower branches often compound and many-flowered, not 
simple and 8- to 5-flowered—a character which is varia- 
ble and therefore unimportant as a basis for specific sep- 
aration. 
The basal portion of the lip is described as being 
broader than the anterior portion in both species, con- 
trary to remarks made by Reichenbach following his 
description of O. chrysopyramis. 
Again, the wings of the column, a character which 
was considered of great consequence in separating the 
concepts, appear to be highly variable in Reichenbach’s 
own figures. Indeed, the column-wings shown in the 
pen drawing on the type collection of O. pyramidale 
appear to be a close approximation to some of those de- 
picted by Reichenbach for O. chrysopyramis.
