Trifolium uintense 



Trifoluun dasyphyiimnS. Wats. Bot. King Exp. 60, in part. 1871. 



Not T. dasypliyllum Torr. 



Cespitose,subacaulescent perennial ; stipules large and scarious ; 

 petioles 1-4 cm. long, sparingly strigose ; leaflets oblanceolate, 

 broadest above the middle, acute and mucronate, entire, 1-2 cm. 

 long, sparingly pubescent or glabrate above ; peduncle about 6 

 cm. long, sparingly strigose ; head obovate, rather few-flowered ; 

 bracts lanceolate, 5-8 mm. long, 3-nerved, slightly if at all 

 scarious-margined ; calyx only slightly pubescent ; tube 2.5 mm. 

 long; teeth subulate-setaceous, about 7 mm. long ; corolla purple, 

 about 15 mm. long; ovary pubescent, about 6-ovuled. 



This is a member of the T. dasyphylbiin group, but differs from 

 its relatives in the broader, decidedly oblanceolate leaflets and the 

 3-nerv^ed bracts.

Trifolium inaequale 



Cespitose glabrous perennial, with very short stems ; stipules 

 ovate, short-acuminate, about i cm. long; petioles 3-10 cm. 

 long, glabrous ; leaflets oblanceolate or oblong, acute or obtuse, 

 minutely denticulate, rather fleshy, 1.5-3 cm. long; peduncles 

 1—2 dm. long ; heads sub-globose ; bracts ov^ate or lanceolate, 

 5-7 mm. long, usually shorter than the calyces, usually cleft or 

 toothed at the apex ; calyx glabrous ; tube 3 mm. long ; teeth 

 unequal, the upper 2-2.5 mm., the lower 3.5-4 mm. long, lance- 

 subulate ; corolla purple, about 1.5 cm. long; ovary 4-ovuled ; 

 legume glabrous, stipitate. 



This is related to T. Panyi and T. iiuvitajicnsc. From the 

 former, it differs in the decidedly unequal calyx-teeth, the nar- 

 lower and smaller, ovate instead of obovate, bracts and stipules, 

 and the less sharply denticulate leaflets ; from the latter in the 

 larger size and the ovate instead of obovate bracts.
