19 MALACI. 



Pods narrowly oblong to nearly linear, partly to wholly 2- 

 celled, inclined to be fleshy, not inflated, rather laterally flatten- 

 ed to conspicuously oljcompressed, pubescent but never woolly, 

 smooth in A. succumbens, sessile, 2.5-7 cm. long, mostly reddish 

 and racemose, capitate in the A, Parryi group. Stems tufted, 

 erect, spreading, with few internodes but never aeaulescent. Pe- 

 duncles about terminal. Calyx teeth and bracts inclined to be 

 lax and long. Flowers large, about 2 cm. long. Calyx cylindri- 

 cal and with teeth over half tlie whole. Petals broad, short- 

 clawed. Leaves long and narrow, with many large, broad and 

 obtuse to barely apiculate leaflets, and large and hyaline stipules 

 which are not couiuito above. Perennials, except A. succum- 

 bens, not woody. Pubescence of leaves shaggy, puberulent and 

 only ashy in A. ensiformis, and silvery and appres?ed in A. 

 Layneae. The sections of this group though loosely related are 

 nearer to eachother than to other groups. 



KEY. 



A. Flowers capitate, few, white. Calyx almost as wide as long. The 

 pods linear-lanceolate, much obcompressed, sulcate dorsally, acumi- 

 nate, very fleshy, cartilaginous when dry, about 3 cm. long and 5 mm. 

 wide. Plants densely pubescent. Compare this group with the Sar- 

 cocarpi.
