Phyllanthus nanus Millspaugh, sp. nov. 



A low, spreading, glabrous perennial, about 5 cm. in extent, 

 with thick, strongly imbricated leaves. Root thick, branching, 

 giving off a mass of thread-like rootlets. Stems many, springing 

 from the rootstalk, very short (1-1.5 cm.); branches diffuse, 

 rather thick and striate, 1-2 cm. long. Inflorescence dioecious, 

 biflorate, in the axils of the apical leaves of the short branchlets. 

 Leaves thick, glabrous, ovate, cordate, acute, entire, 1.3X1- 

 2.3x1.75 mm.; petioles very short; stipules entire, aristate from 

 a deltoid base, the upper half withered to a dark brown color. 

 Flowers sessile or nearly so; sepals 5, equal, ovate, acute, strongly 

 striate-keeled ; glands 5, verrucoid, minute; staminal column twice 

 the length of the anthers; anthers 2, transversely connate in an 

 apical ring; female calyx as in the male but nearly twice the size; 

 ovary 3-carpelled, 6-celled, nearly sessile; styles 3, short, bifid to 

 half their length, the stigmatic apices cleaveate; capsule depressed- 

 globose, glabrous; seeds dark brown, sharply angled, 0.9X0.75 mm.
