united into a tube, anthers short, oblong: styles elongated; capsule 
reticulated, 12-15 mm. long; seeds brown, smooth with ventral 
angle; embryo very minute at the base of the copious albumen. 
This remarkable species was collected in southwestern Colorado 
by Mr. Alfred Wetherill. He writes that it grew in damp alkaline 
localities under shady cliffs and that the flowers were very fragrant. 
5. DELPHINIUM scAPosUM Greene. Found blooming at Man- 
cos in June; appearing about the time the common D. ézco/or was 
going to seed. 
6. ARGEMONE HISPIDA Gray. This has apparently been con- 
fused with Argemone platyceras Link & Otto. It is very different, 
and both are found in the same localities, Pueblo and Morrison. At 
Denver A. hispida is not found while 4. plalyceras is common.

mon. 
12. THELYPODIUM AUREUM. Biennial, 4-1 m. high, branch- 
ing diffusely from the base, the lower part of the stem sparsely 
retrorse, hairy; whole plant glaucous, leafy to the raceme: radical 
leaves oblanceolate, dentate, on margined petioles; cauline sessile 
ovate, auriculate, clasping, acuminate entire: sepals and petals — 
- bright yellow; petals % longer than the sepals, cuneate-oblong 
above the broad claw: pods (immature) very slender, 4-5 cm. 
long, with a stipe 4-6 mm. long, numerous on the 8-15 cm. long 
= raceme: seeds oval, cotyledons apparently incumbent. —Durango. 
‘This differs from Thelypodium in the color of its flowers, but in 
oe an else seems to agree. 
13. STANLEYA ALBESCENS Jones. My specimens differ from the 
type as described, in the leaves being all lyrate except those from 
the root, which are pinnately parted into 10 to 14 broad oval entire
