trorsum tortis et convolutis; staminibus ad contractionem tubi insertis. In Rio de Janeiro, v. v. 
in montibus Organensibus, in herb. meo (4056). 
I found this species in flower in January 1838. The fistulose scandent branches are 
4 in. thick, with axils 7 in. apart; the opposite leaves are 34-6 in. long, 21-33 in. broad, 
on petioles 12-2 in. long, which are inserted 2—1 in. above the base of the blade; panicle 
spreading, 3-4 in. long, subtomentous; peduncle bare at the base, 2 in. long; its 8 
branches 2 in. long, each bearing 5-6 approximate flowers, on pedicels bracteate at 
their base, bibracteate in the middle, 8 lines long; bracts 6 lines long, 1 line broad; 
sepals the size of the bracts, reticulately veined, each having within at the base a small 
alternate scale; tube of corolla 1 in. long; segments 9 lines long, 4 lines broad ; anthers 
slender, 43 lines long, acutely acuminate, and sharply biaristate at the base, subpuberu- 
lous behind; disk 5 free fleshy roundish lobes nearly as long as the 2 roundish glabrous 
ovaries; style slender; clavuncle incrassate, glandular, supported upon a peltate 
membranaceous appendage.

pedalibus, paullo arcuatis, teretibus, striatellis, cinereo-nigrescentibus, apicibus subangustatis arcte

meo (4058) ; v. s. in herb. Mus. Brit. Itagoahy (Bowie and Cunningham). 
The branches are 3 lines in thickness, very fistulose, rigid, with axils 8 in. apart; the 
leaves are 44-51 in. long, 3-4 in. broad, on petioles 14-14 in. long, inserted ¿ in. within 
the border. The fructiferous peduncle, with the cicatrices of 2 abortive flowers, is 13 in. 
long; the follicles are 104 in. long; the seeds (including the long glabrous rostrum 
6 lines) are 14 lines long, 1 line broad, with an apical spreading coma 13 lines long; 
funicle beneath the ring of the coma very short, but distinct. 
The follicles in Bowie and Cunningham's specimen, not yet ripe, are 74 in. long, 
4 lines broad. 
A drawing of this species in fruit, showing the carpical structure, and the analysis of 
its seeds are given in Plate XIX.

The leaves are 44 in. long, 2 in. broad, on a somewhat slender petiole ¿ in. long, in. 
serted 1 line within the margin.
