RYDBERG: STUDIES ON THE Rocky MountTatn Frora 238 
¥ Thelypodium macropetalum sp. nov. 
_ A glabrous perennial, 4-6 dm. high : basal leaves oblanceolate 
or spatulate, short-petioled, 2-5 cm. long: lower stem-leaves ob- 
long, obtuse, sessile, with rounded auricles at the base, 5-6 cm, 
long; upper leaves lanceolate-sagittate, acute; pedicels in fruit 
. about 1 cm. long, divaricate: sepals about 5 mm, long, purplish 
with white margins ; petals purple, spatulate, long-clawed, nearly 
three times as long as the sepals: pods 4—5 cm. long, ascending 
or erect and somewhat incurved. 
This is related to 7: sagittatum (Nutt.) Heller and 7. panicula- 
tum A. Nelson. From the former, it differs in the smaller leaves, 
the rounder auricles, the erect, not reflexed nor spreading pod; and 
from the latter by the much longer petals, It grows at an altitude 
of 1,000-1,200 m.

v Thelypodium Utahense sp. nov. 
Annual or biennial: stem 4-6 dm. high, sparingly pubescent 
low; leaves all lanceolate in outline, 5-10 cm. long, lanceolate, 
Slabrous ; segments broad and crowded, oblong-lanceolate to tri- 
angular: pedicels very short, in fruit scarcely more than 1 mm, 
long: sepals oblong, about 2 mm. long : petals spatulate, almost 
twice as long, white : pod about 3 cm. long, strongly reflexed. 
This is probably nearest related to S. reflexum Nutt., which is 
decidedly hispid on the stem and the veins of the leaves and has 
Much narrower leaf-segments. It grows at an altitude of about 
600 m.
