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 ; teet 
villous, 4-5 mm. long, subulate-setaceous ; corolla rose oF par: 
plish, 13-15 mm. long; ovary 4-ovuled; legume sparingly hairy, 
stipitate. 
This species belongs to the 7. Jongipes group. It is probably 
most nearly related to 7. Rydbergii and T. pedunculatum. 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 7. longipes and T. Rusbyi 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 
mucronate at the apex, finely denticulate, 2-4.5 cm. ong, 
rous above, sparingly hairy beneath; peduncles several, ae 
dm. long; heads globose ; flowers reflexed in fruit on asd 
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 J. /atifolium, from which it weit 
mainly in the different habit, larger size, longer peduncles ee 
larger ovate instead of oval or obovate leaflets. ;
