lobes linear-subulate, longer than the tube. Corolla bluish, a third ex- 

 ceeding the calyx ; standard and wings clearly exceeding the keel. Ovary 

 appressed, pubescent-hoary. 



Patagonia, in dry places by Rio Chubut, near Lago Musters and Car- 

 ren-leofu. Root 15-25 cm. long. Its acute, elliptical or lanceolate leaves 

 distinguish it from A. meyenianus Speg. and A. philippii Speg.

 lower concrete. Racemes capitate, lax, longer than the leaf. Flowers 

 rather large, yellow-violaceous, spreading. Bracts small. Calyx and

The pubescence of the calyx may be either white or black. Speci- 

 mens from South Patagonia have the leaflets smaller and broader than 

 the type (3.9 by 2.3 mm.), and more obtuse or nearly 2-lobed ; calyx with 

 white silky pubescence. Legume subacute both ways, glabrous, with the 

 upper suture introflexed. (Speg.) Large handsome flowers and hard fruit. 



7. A. DISTINENS Macl. (Phaca distans A. Gray, 1854, non 



A. distans Fischer, 1853.) 



Slender, finely pubescent annual. Stipules ovate-subulate, partly 

 united. Leaflets 9-13, narrow-linear, obtuse, involute when young. 

 Racemes axillary, spike-like, many-flowered. Pedicels short, recurved. 

 Calyx white-brown, hairy. Corolla yellow-white. Legume ovoid, sessile, 

 i cm. long ; the sutures slightly intruding.
