This species has a very long, deflexed beak to the keel of the corolla, hooked 

 round so as almost to complete a spiral ; in this respect it resembles, to a consider- 

 able extent, a Phaseolus ; its pods and seeds are however totally unlike those of any 

 Phaseolus. Nothing requires to be added to Mr. Baker's excellent description. 



In reducing this species to Canavalia Mr. Kurz has omitted to state that he was 

 only following the treatment already proposed by Dr. Wallich in a manuscript note 

 dated " 25th October 1833."

So remarkably like the preceding that without flowers it is difficult to distin- 

 guish the two species. The flowers are, however, very unlike ; in the present plant 

 they are less than half the size and have a much shorter beak to the keel than in 

 I), grande. Again nothing can be added to Mr. Baker's clear description.

This, with the next species, makes a very distinct section of the genus 

 Dysolobium. 



4. Dysolobium tetragonum Prain ; stems woody, brown-pubes- 

 cent, leaves subcoriaceous entire lanceolate prominently veined ; with 

 Copious adpressed bristly hairs, racemes many-fld. sub-sessile or shortly 

 peduncled, corolla middle-sized, pod stout short straight square, the 

 angles winged, the faces densely clothed with persistent firm short 

 spreading greyish-brown hairs. Psophocarpus sp., Bak. in Flor. Brit.
