rated Up, from the first and the last in its lip not having 

 the edges incurved, and from all in the singular truncate 

 form of this helmet-shaped organ, which is flattened from 

 front to back and not laterally. 



5. Cfuliginosum (Lindl. in Bot. Reg. 1841. misc. no. 168); 



C. tridentati vultu, sepalis petalisque oblongis acutis re- 

 flexis, labello cucullato carnoso integerrimo v. minute 

 serrulato patente, columna brevi ecirrhosa apice in setam 

 producta, anthera parva (effoeta?). ? This sin- 

 gular plant has the habit of C. tridentatum, but its flowers 

 are in a dense erect raceme, and of a deep green colour, 

 spotted with a dull blackish purple, so as to look as if 

 they were soiled with soot. The sepals and petals are 

 spotted, oblong, acute, and reflexed, so as to hang down- 

 wards. The lip, on the other hand, is fleshy, hooded, 

 stained with pale purple, and either entire at the margin, 

 or very slightly serrated ; but it does not cover over the 

 column as is usual in the hooded Catasetums : on the 

 contrary it spreads away at almost right angles. The 

 column itself is short, deep green, and produced at the 

 point into a straight bristle, in front of which is placed a 

 small and imperfect anther. Judging from the evidence 

 we possess concerning C. tridentatum and cristatum, we 

 should suspect it to be a male form of C. atratum, or 

 some such species. That, however, must remain for 

 future inquiry.
