346 FLORA NIGRITIANA. 
tegentes, calycis collo subnudo. Lacinie calycinz, petala, et 
stamina caducissima. Anthere erostres, uniporose, wni- 
formes, connectivo infra loculum breviter producto, in fila- 
mentum articulato, ad insertionem subintegro. 
Although, as already stated, this plant may be separated 
from the Asiatic Osbeckie by the form of the connectivum of 
the anther, yet this character is so slight, and the anthers of 
some of the Asiatie species are as yet so little known, that I 
have preferred considering it as forming with the following 
species a section of Osbeckia to establishing it as a distinct 
genus. The form of the calyx brings it nearest to those 
species which Korthals proposes to separate under the name of 
Ceramiocalyz, on account of characters which do not appear to 
me to be either definite or constant enough to found a genus.

The stem of this species, although hard, is probably herba- 
ceous, not frutescent. I have been able to examine the anthers 
but very imperfectly, on account of the insufficiency of the - 
specimens. 
The Osbeckia Senegambiensis, Guill. et Perr., from Sene- 
gambia, if the anthers are really all equal and similar, is pro- 
bably a third species of this group, the two small appendages, 
mentioned as being on the filaments near the summit, being 
probably the extremity of the connectivum where it is inserted 
on the filament. 1
