500 LX. SAMYDACEH (MASTERS). [ Byrsanthus. 
cemose; rachis twice the length of the petiole. Flower-tube a 
shaped, longer than the 5 deltoid valvate downy calyx-lobes. Petals 
ovate, acute, very thick, valvate or slightly infolded at the margins, 
hooded at the apex, spreading slightly, exceeding the sepals. Fila- 
ments rather shorter than the petals, thread-like, incurved and often 
5 ard twisted in eestivation; anthers globose, didymous; connective 
slightly prolonged. Ovary completely adherent to the tows ae 
1-celled, many-ovuled; styles 5, awl-shaped, distinct to the base, an 
shorter than the stamens. 
Upper Guinea. Gambia, Park. 
Lower Guinea. Congo, Chr. Smith! 
This no doubt is the plant intended by Brown, as it occurs in Prof. Smith's herba- 
rium. It differs from the preceding in the spreading petals, completely inferior yarn 
and other minor points. I have not seen Park's specimen, but judging from the ha av 
I consider it possible that that may belong to the former species, which is known to 
a native of the Gambia.
