 Amazonica: v.Jlorem s. in lib. meOy San Carlos, Rio Negro {Spruce). 



As mentioned in a preceding page (p. 172), I found this single flower entangled in the 

 paniele of my specimen of Chytroma Spruceana (Spruce, 3695) from San Carlos, on the 

 upper branch of tlie Uio Negro, just within the confines of Venezuela. The pedicel is \\ 

 line long ; the sepals 1 J line long, 1 line broad ; the larger petals are 8 lines long, 6 lines 

 broad ; the androphorum coiled up, 4 J lines in diameter, expanded 9 lines long. 



This singular genus seems to approach Cariniana in its 3-locular ovary, erect ovules, 

 and long style, and to agree generally in its floral parts ; but it diifers in its andro- 

 phorum, unilaterally expanded by the addition of its anomalous purse-shaped hood.

 Kg. 1. The ovary, surrounded by the sepals, to show the epigynous annular disk to which the £ 



phorum is agglutinated by the intervention of the claws of the petals.

attachment to the disk ; the inferior ovary is also seen where ovnles, supported by fui 



radiate from the central axis : all nat. size.
