A very minute slender perfectly glabrous annual herb, forming dense 

 moss-like tufts Va — 1 in high. Leaves numerous, all radical, filiform, 

 strict, erect, terete, gradually tapering to an acute point. ■ Scapes very 

 short in the flowering stage, lengthening to one-half or three-quarters 

 the length of the leaves when in fruit. Bracts 3—5, erect or erecto- 

 patent, linear-lanceolate to ovate-lanceolate, acute, thin and membranous, 

 V12 — Vs m long- Heads unisexual; males not seen. Ovaries densely 

 crowded within the bracts, usually form 10 to 20, shortly stipitate, ovoid 

 or oblong-ovoid, smooth, pale jellow-brown or reddish. Styles numerous, 

 very delicate, forming a spreading brush at the tip of the ovary, and 

 often much longer than it. Ripe fruit elliptic-ovoid, pale jellow-brown 

 with a dark spot at each end. 



New -Zealand: So far this has only been found on the sandy 

 shores of Lake Ngatu, a small lake situated behind the coastal sand- 

 dunes about six or eight miles north of Ahipara, but doubtless it will 

 be found on the shores of some of the numerous similar lakes existing 

 in the North Cape peninsula. It principally differs from the Australian 

 species in the more numerous bracts, and (judging from Dr. Diels plate) 

 in the stricter and more densely tufted habit.
