FLORA NIGRITIANA. 307 
- 
Brazilian D. violacea, whose violet-coloured bracts are straight 
and erect, whilst in the West African one they are always reflexed, 
as in another yet unpublished Brazilian species, (Gardner, n. 
2117), in which however the flowers are very different. 
Two species of Canavalia are mentioned as inhabiting W. 
Tropical Africa, the C. obtusifolia, DC., common on the 
sea-coast of Senegal and Guinea, and of East Tropical Africa, 
Asia and America, and C. gladiata, DC., from Guinea, a 
commonly cultivated East Indian species. The first of these 
is deseribed by Schumacher and Thonning under the name of 
Dolichos obovatus ; and that species is followed by a D. ovali- 
folius, which is unknown to us, but judging from the ex- 
pression “cetera uti in precedenti," it may be another Cang- 
valia.
