 inches high; herbage spreading-bristly, the bristles pustulate-dilated at base; leaf- 

 blades narrowly linear or linear-oblanceolate, very dark green, ^^ to li/4 inches 

 long; spikes soon somewhat loose, i/4 to II/2 inches long; calyx-lobes linear-filiform, 

 short-villous and sparsely long-bristly; corolla ^^ to IV2 lines broad; nutlets 4, 

 ovate (the apex obtusish), 1 large and not evidently margined, 3 slightly smaller 

 and with a narrow whitish margin, conspicuously sprinkled on back with whitish 

 papillae on a brown ground, the ventral side convexly 2-planed, the ventral suture 

 opening downward into an open forked areola; style i/i longer than nutlets. 



Rich soil pockets in caiion bottoms of rocky desert ranges or lava flats, 200 to

Geog. note. — Cryptantha inaequata represents a case of an adequate but long unrecognized 

 species whicli masqueraded, so to speak, in the shadow of C. holoptera. Its nutlets, too, save 

 for the lineate margin, resemble closely the smaller nutlets of the four in Crj'ptantha angustifolia. 

 Cryptantha inaequata has, however, the advantage of differentiating characters other than those 

 of the nutlet. That it escaped critical notice previous to 1922 is due, doubtless in part, to its rarity. 

 Even to this time few collections have been made. — Eastern Mohave Desert : Lavic, Jepson 15,456 ;
