Very like A 7 , oleracca Lour, and perhaps not separable as a distinct 

 species. Both Grisebach and Bentharn treat them as distinct, relying on 

 the following characters for N. plena : Pinnx, 3-5 pairs ; rhachis bearing a, 

 sessile gland just below the lowest pair of leaflets. Leaflets 12-40 pairs. 

 Pod larger (to 5 cm. 1.), more erect. Seeds 5-20. Plant more terrestrial. 



19. Parts 



of the flower in 5's or 4's. Stamens as mam- 

 as, or twice as many as, the petals ; anthers without 

 glands. Pollen granules numerous, distinct. 



41. DESMANTHUS Willd. 

 Perennial herbs or undershrubs. Leaflets very small ; a 



,/ 



sessile cup-shaped gland just below the lowest pair. Stiuples 

 bristle-like, persistent. Flower- 

 heads on solitary axillary stalks. 

 Floral parts in 5's. Calyx cam- 

 pa nulate, toothed. Petals free 

 or slightly cohering. Stamens 

 10 (rarely 5), free, exserted. 

 Pod linear, Hat-compressed, 2- 

 valvecl. 



Species 8 or 9, natives of 

 North and South America and 

 West Indies, one (D. virgatus)
