2G Zoopsis 



Hab. in Brasilia boreali et Venezuela australi contermina, ad fluvios 

 Neyro, Uaiipes, Casiquiari, etc., iibi in aggeribns nmbrosis, rivuloriim 

 ripis, trnncis semiputridis et fructibus lignosis decisis sat frequenter 

 viget. 



This species is fond of growing on the decaying bark of old or prostrate trees, and 

 on otlier semiputrid vegetable matters. Luxuriant specimens were gathered on fallen 

 pods of Parivoa excelsa. I found it once growing intermixed with male plants of 

 C. integrifolia, from which its olive-green catkins at once distinguished it ; C. intcgri- 

 folia having them white, besides a distinctly leafy stem. 



The radicles originate in tubercles (of one or two cells) placed here and there along 

 the underside of the eosta ; but even the tubercles are not developed unless radicles be 

 needed for attaching the frond at that point. In the male spikes, a few more cells 

 added on to these tubercles transform them into under-leaves, or bracteoles. The 

 fronds, whether primary or secondary, often root also at the attenuated point.
