According to notes sent by our colleague Desruisseaux, 

 a wild variety of Phaseolus heholus is found in Anjouan 

 (Comoro Islands) with flowers similar to those of the Reunion 

 species. The leaves are smaller, dark green in colour, with a 

 partially circular light-coloured stain occupying the lower 

 third portion, the edges undulate; stems villous, creeping, 

 and climbing ; the pod is hairy and measures from 6 to 7 cm. ; 

 the hairs are upright, and the pod turns blackish when ripe. 

 It contains from eight to twelve almost rectangular chestnut- 

 coloured seeds, with darker dots and a whitish hilum. 



M. Desruisseaux thinks this variety might serve as a 

 cover crop. 



Thanks to M. Desruisseaux, who has kindly forwarded 

 us samples from the Comoros, we' have been enabled to 

 study the composition of this plant. 



We have obtained about the same results as for those 

 grown in Mauritius.
