12 Colorado Plants. — [ZOE 
corymbs umbel-like, small and compact on naked peduncles 
from 2 to 8 cm. long; the branchlets are usually perpendicular 
to the axis and the involucres are sessile, perpendicular, erect, 
and secund on the upper side. 
ERIOGONUM CORYMBOSUM Benth. JLeaves from narrowly 
linear 5 mm. wide to oblong 2 cm. wide, crenate-undulate on 
the margins and densely white-tomentose on the under surface. 
The leaves are either clustered near the root or are along the 
stem to the long, naked peduncle of the corymb, which is usually 
spreading but sometimes almost capitate. The stems, branches, 
and branchlets are densely tomentose and seem coarse compared 
with the var. J/eptophyllum. This variety has long, linear- 
lanceolate leaves with revolute margins, somewhat tomentose 
below, almost glabrous above, corymbs on naked peduncles, 
barely surpassing the leaves, loosely branched, sparingly 
flowered. The species is usually found on slaty hill-sides, while 
the variety is found in loose soil under the pifions and cedars or 
along the banks of dry alkali streams. It is uncertain whether 
the variety belongs to £. corymbosum or to E. microthecum. 
SMILACINA STELLATA Desf. This is described as having 
blue-black berries. All that have been seen in Colorado, from 
observations extending over several years, have the berries at 
first green, striped with red, but when fully ripe they are red all 
over. The species in California has been collected with the red- 
striped berries. Doubtless, if collected or observed later in the 
season, the berries would be found as in Colorado. 
; FRITILLARIA ATROPURPUREA Nutt. This was collected at 
Mancos with both perfect and staminate flowers, showing a 
tendency to become dicecious. No pistillate flowers were found. 
CaLocuortus Nurrau Torr & Gray. This usually has 
white petals, but at Grand Junction it varies through all the 
shades of pink to crimson-purple and also white. C. Gunnison? 
shades through the blue shades to the bluish-purple and white.
