Amorpha nitens n. sp. 



A branching, nearly glabrous shrub i.5~3 m high with glossy, 

 chestnut-brown twigs and shining leaves. Leaves i2-25 cm long ; 

 leaflets 7-19, thin, oblong-ovate or ovate, 2-6 cm long, obtuse, 

 rounded at the base, lower surface dull and sparsely pubescent or 

 glabrate, the upper surface appearing when fresh as if varnished : 

 racemes slender, usually solitary, i2-25 cm long : calyx obconic, 

 about 3 mm long : sepals short and rounded, or the three lower 

 short-pointed, ciliate on the margins: legume about J mm long, 

 narrow, much curved and nearly glandless. 



The very glossy leaves and twigs in the growing plants are striking characters. 

 The much-curved legumes suggest A. fruticosa L., 67 but in the last named spe- 

 cies they are conspicuously marked with raised glands, while in A. nitens they 

 are glandless, or nearly so. 



The habit and leaf characters are more like A. virgata Small, 1. c, which, 

 on the contrary, has dull or glaucous twigs. 



The type material was collected in a swamp near Waynesboro, Georgia, 

 July 24, 1900, and is preserved in the Biltmore Herbarium. 



Amorpha angustifolia (Pursh) 

 A. fruticosa angustifolia Pursh. 



A much-branched shrub i.5-3 m high, the young growth finely 

 strigose-pubescent with grayish hairs. Leaves 7-2c cm long ; leaf- 

 lets, 9-27, elliptic to linear-oblong, 2~4 cm long, mostly acute at 

 both ends, the midrib projecting in a prominent awn-like cusp, 

 both surfaces minutely puberulent : racemes single or a few in a 

 cluster, 5~20 cm long : calyx about 3.5 mm long, the two upper sepals 

 rounded, the lower sharp-pointed, the middle one the longest : 

 standard broadly obovate, short clawed, 4. 5-5 mm long: legume 

 6-7 mm long, strongly curved, distinctly marked with raised glands. 

 Banks of streams, Texas and northward. 



Amorpha texana mollis nom. nov. 



A. Iczvigata fubescens A. Gray, PI. Wright. 1:49, 1852. Not A. Alb- 

 escens Willd. or Schlecht. 



The above form apparently differs only from A. texana Buckley 68 

 in having all the parts clothed with fine, soft tomentum. It can-
