 broad; fruiting calyx ovoid or oblong-ovoid, ascending, 2.5^ mm. long, symmetrical; mature 

 calyx-lobes slightly connivent, silky-strigose on the margin, midrib thicker and usually sparsely 

 hispid; nutlets 4, similar, oblong-ovoid, 2-2.5 mm. long, muriculate or tuberculate, narrowly 

 winged on the margin ; groove broadly forked below, often forming a triangular areola ; style 

 distinctly surpassing the nutlets.

 lower surface, less so on the upper ; spikes usually in pairs, bractless or rarely with 1 or 2 

 bracts below, 2-6 or rarely 10 cm. long, usually becoming loosely flowered in age ; corolla in- 

 conspicuous, 0.5-1 mm. or rarely 2 mm. broad; fruiting calyx distinctly accrescent, 3-5 mm. 

 long, symmetrical, ascending on short pedicels ; mature calyx-lobes ovate to ovate-lanceolate, 

 somewhat connivent, thin, margins more or less tawny, hirsutulous, midrib slightly thickened 

 and sparsely hispid; nutlets 4, heteromorphous, the body oblong-lanceolate to lanceolate, 2-2.5 

 or rarely 3 mm. long, muricate or verrucose, axial one not margined, the other three with 

 usually broad wings, these either entire, crenate or lobed; style surpassing the body of nutlets.

 typical species, and knife-like. Southern California deserts; Argus Mountains, Darwin, and San Bernardino 

 Mountains. Type locality: Argus Mountains, Inyo County, California.
