RyDBERG: Rocky MOUNTAIN FLORA 425 
cinereous-strigose or more glabrate beneath; peduncles about I 
dm. long; raceme 4-10 cm. or in fruit even 2 dm. long; bracts 
ovate to lanceolate, scarious ; calyx cinereous-strigose ; tube nearly 
3 mm. long; teeth lance-subulate, 5 mm. long, attenuate ; corolla 
rose-purple ; banner 15-18 mm. long; keel 18-20 mm.; loments 
minutely strigose ; internodes 2-5, 6-8 mm. long, 5—6 mm. wide ; 
nodes narrow, 2.5 mm. or less. 
This is related to the subarctic H. Mackenzii, from which it 
differs in the denser pubescence on its calyx, its broader calyx-teeth, 
its fewer and larger internodes of the loment, its taller habit, 
broader bracts and lighter and redder flowers. It grows on hill- 
sides at an altitude of 1400-2000 m.

¥Y Lathyrus brachycalyx sp. nov. 
Perennial with a creeping rootstock; stem simple or slightly 
branched, 1.5-3 dm. high, usually finely pubescent, sharply 4- 
angled ; stipules semi-sagittate, 5-10 mm. long, I.5—-3 mm. wide, 
pubescent ; rachis 2-5 cm. long, somewhat winged; leaflets 2—5 
pairs, linear-oblong or oblanceolate, firm, strongly veined, finely 
pubescent, acute at both ends, 1-3 cm. long, 2-8 mm. wide; ten- 
drils of the lower leaves reduced to mere tips, those of the upper 
leaves better developed, but usually simple ; peduncles 5—10 cm. 
long ; raceme short, 2-6-flowered ; calyx puberulent; tube 4-5 
mm. long; upper teeth broadly triangular, scarcely 2 mm. long, the 
rest lance-subulate, the lowest one 3 mm., rarely 4 mm. long; 
corolla purple, 2—2.5 cm. long; legume glabrous, 3-4 cm. long, 7 
mm. wide. 
This species has been confused with ZL. decapetalus and is 
closely related to it. It differs in the much shorter calyx-tube 
and calyx-teeth, the broader, more upturned banner, the more 
pubescent foliage and less well developed tendrils. It grows 
on hillsides and in cafions and washes at an altitude of 1400- 
2500 m,.
