Said by Rchb. to reseinble 0. cimiciferum (nr. 22). The bracts nre described as 

 very niinule. ihe panicle ihree feet loug, the lip triangular, about as long as ihe pe- 

 tais , angular at ihe base , ihe crest composed of one narrow erect beel sloping to 

 ihe base, having a few lobes and hooks on each side, and a downy space in front 

 of the keel. The flowers are smaller iban in 0. cimiciferum. A fragment communi- 

 cated by Rchb. shows thal this is a correct statement. The plaiil is very near 0. 

 examinans.

Diese zwei Arten stehen dem Oncidium cimicifernm Rchb. fil. sehr nahe. In Be- 

 zug auf Tepala und die sammtige Umgebung des Kieles isl 0. trulla sebr uberein- 

 slimmend niit diesem , allein es fehien die Zahnchen vor dem Kiele. Die Saule hat 

 Ecken , die Deckbiiitier sind nichl gross und kappig. Das Oncidiurn cocciferum ist 

 sebr verschiedcn durch kleine Deckblaiter, fast gleich breite Sepala und Tepala, man- 

 gelnden Sammineck beiderseits des Kiels , keine Fingerchen vor demselben, Ecken 

 der Saule u. s. w.
