branched; branches densely tufted, about I cm. long, clothed by 

 the persistent leaves : leaves densely imbricated and crowded, the 

 persistent ones of previous years, black, the fresh ones gray, 

 spatulate or almost terete by the strongly revolute margins, ob- 

 tuse, dilated at the base : peduncles erect, 5-IO mm. tall, simple; 

 involucres solitary, turbinate-campanulate, 2.5 mm. high, fluted: 

 segments triangular-ovate somewhat converging calices, villous at 

 the base, 2.5-3 mm. long ; segments unequal, the 3 outer segments 

 oval, the 3 inner obovate, all obtuse : filaments villous at the base : 

 achenes 3-angled.

This excellent little species has posed as Eriogonum acaule ,bvX 

 a casual observation is sufficient to demonstrate the impossibility 

 of such a disposition. Besides its more slender habit, the white 

 woolly pubescence in the case of E. acaule and the gray canescent 

 pubescence in the case of E. minimum serve as a ready means of 

 separation ; further, the smaller fluted peduncled involucres and 

 the calices villous only at the base cannot be specifically associated 

 with the corresponding organs of Eriogonum acaule. The original

v Eriogonum clavellatum. 



Perennial from a thick, woody base, pale green. Stem gnarled, 

 branched; branches clustered, thinly tomentose; leaves fleshy, 

 strongly revolute, cylindric-clavate, 1-1.5 cm. long, obtuse, glab- 

 rous without; petioles slender, 1-2 mm. long, tomentose: pedun- 

 cles club shaped, 1-2 cm. long, simple or rarely forked: bracts 

 scale-like: involucres deciduous, long campanulate, 4 mm. long, 

 rib-angled ; segments acute, dark green, erect : calices glabrous, 

 pink, (?) 3.5 mm. long, urn-shaped ; segments saccate at the 

 base, bent out at the middle, crisped, the 3 outer fiddle-shaped, 

 apiculate, the 3 inner rather cuneate, narrower than the outer, 

 acutish : filaments villous at the base : achenes 3-angled, glabrous. 



On rocky hill, Barton Range, southeastern Utah. Summer. 



A low and one of the more peculiar species, most closely re- 

 lated to Eriogonum tricacfolium and E. bicolor from which it can be 

 separated by the club shaped leaves and peduncles, the struc- 

 ture of these organs being unique in the genus. The branches 

 of the inflorescence and the flowers are loosely articulated and 

 easily fall away.
