umbellatis densissimis terminalibus hemisphaericis vel subglobosis 1-2 cm. dia- 

 metro; pedunculis 20-50 filiformibus 2-8 mm. longis parce pilosulis vel glabris. 



Small caulescent herb, 2-8 cm. tall; stems solitary or sometimes with 1 or 2 

 smaller ones in addition, the main ones slender, rigid, erect, dark brown or black- 

 ish, more or less flattened and angle-margined, rather densely and loosely pilose 

 with gray, irregular, mostly more or less appressed hairs, bearing a whorl of many 

 cauline leaves 0.8-3..5 cm. from the base, the side stems without the cauline 

 whorl of leaves; basal leaves very numerous, densely rosulate, recurved-reflexed 

 to the ground, narrowly linear, rather rigid, 8-12 mm. long, less than 0.5 mm. 

 wide, subulate-tipped, glabrate, 1-nerved, not fenestrate; cauline leaves similar 

 but ascending-erect; inflorescence a very dense terminal umbel which is hem- 

 ispheric or almost subglobose, 1-2 cm. in diameter on the main stems, 6-8 mm. 

 in diameter on the secondary stems, composed of 20-50 or more short pedunculate 

 heads, each peduncle subtended by a leaf-like bract; peduncles filiform, 2-8 mm. 

 long, sparsely pilosulous or glabrous; sheaths absent, represented by an equitant- 

 navicular bract to about 7„5 mm. long, minutely pilosulous, acute at the apex; 

 heads obconic or subhemispheric, 3-4 mm. in diameter; receptacle short-pilose; 

 involucral and receptacular bractlets hyaline or whitish, elliptic, about 2 mm. 

 long and 0.5 mm. wide, acute at the apex, sparsely pilosulous on the back; stamin- 

 ate florets: sepals 3, whitish-subhyaline, connate at the base, the free portions 

 elliptic, 1-1.5 mm. long, subacute or rounded at the apex, often with 1 or a few 

 unicellular hairs at the tip; petals 3, white, connate into a slender infundibular 

 tube for L5-2 mm., glabrous, the terminal free portion elliptic-spatulate, about 

 1 mm. long, rounded at the apex, glabrous; stamens 3, borne on the petals at the 

 apex of the tube, included; filaments filiform, 0.4-0.5 mm. long, glabrous, white; 

 anthers white; rudimentary pistil reaching the base of the free filaments; stigmas 

 3, white-capitate; pistillate florets: sepals 3, separate, whitish, elliptic, about 

 1.5 mm. long and 0.5 mm. wide, acute at the apex, sparsely pilose on the back; 

 petals 3, white, spatulate, connate at the middle, free at base and apex, about 2 

 mm. long, to 0.4 mm. wide, rounded at the apex, glabrous; style about 0.5 mm. 

 long, glabrous; stigmas 3, about 0.5 mm. long, white=capitate; ovary narrow- 

 elliptic, glabrous, 3'sulcate, 3-celled, 3-ovulate.
