There are several species of Alysicarpus in Northern Nigeria, 
and as they are mainly determined by fruit characters it is 
necessary that fruits should be collected where possible. A. vagin- 
alis, DC., with a very lax inflorescence and turgid, slightly 
“ moniliform fruit, often black when quite ripe, is according to 
Dalziel, called “‘ Gadiggi,’”” and is a food for horses, sheep, goats, 
etc. It is common in pastures. A. Zeyheri, Harv., first recorded 
here from Upper Guinea, has rather flattened smooth (not 
wrinkled) pods arranged on an elongated axis. In the absence 
of fruits it is difficult to distinguish from a third species, occurring 
in Nigeria, A. rugosus, DC., with very dry, chaffy bracts, rather 
densely arranged and strongly and transversely wrinkled fruits, 
also described by Mr. Lamb as a valuable fodder and an ubi- 
quitous weed of arable land in Northern Nigeria. It is evidently 
not distinguished by the vernacular from 4. vaginalis. The 
species of this genus need study in bee field, especially in regard 
to the form and variation of the f

This is an undescribed species which will be dealt with by 
Mr. 8S. T. Dunn in a forthcoming revision of the genus 
Canavalia.
