46 Rydberg: Rocky Mountain flora 



This species is related to L. pnsillus, but differs in the more 

 elongated racemes, "which much exceed the leaves, the smaller 

 flowers of a different color and the short upper lip of the calyx.

Trifolium confusum 



Perennial with a rootstock ; stems erect, simple, 2—3 dm, 

 high, glabrous below, sparingly strigose above ; stipules ovate, 

 acute, about 2 cm. long, glabrous, veiny ; leaflets of the lower 

 leaves oval and rounded at the apex, of the upper ones lanceolate, 

 and acute, 2—3 cm. long, finely denticulate, glabrous or nearly so ; 

 peduncles 5—7 cm. long ; head globose ; flowers reflexed in fruit ; 

 calyx-tube 2 mm. long, glabrous except the villous margin ; teeth 

 villous, 4—5 mm. long, subulate-setaceous ; corolla rose or pur- 

 plish, 13—15 mm. long ; ovary 4-ovuled ; legume sparingly hairy, 

 stipitate. 



This species belongs to the T. longipcs group. It is probably 

 most nearly related to T. Rydhcrgii and T. pediinculatnm. From 

 the former it differs in the nearly glabrous calyx-tube and the 

 rose- colored and larger corollas ; from the latter in the larger and 

 reflexed flowers. It differs from T. longipes and T. Rushyi in its 

 different habit and nearly glabrous calyx.

Trifolium Aitonii 



Perennial with a rootstock ; stem 3-4 dm. high, glabrous 

 below, strigose above ; stipules ovate, short-acuminate, about 2 

 cm. long, veiny ; leaflets ovate, thin, obtuse or rounded and 

 mucronate at the apex, finely denticulate, 2-4.5 cm. long, glab- 

 rous above, sparingly hairy beneath ; peduncles several, 1—2 

 dm. long ; heads globose ; flowers reflexed in fruit on pedicels 

 2—3 mm. long ; calyx pubescent throughout ; tube 2 mm. long ; 

 teeth subulate, about 4 mm. long; corolla about 12 mm. long ; 

 legume stipitate, strigose, about 2-seeded. 



This species is related to T. latifolinvt, from which it differs 

 mainly in the different habit, larger size, longer peduncles and 

 lal'ger ovate instead of oval or obovate leaflets.
