1 2 Colorado Plajiis. [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. I^eaves 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. leptophylhun. 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 pinons and cedars or 

 along the banks of dry alkali streams. It is uncertain whether 

 the variety belongs to E. corymbosum or to E. microtheciun. 



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 dioecious. No pistillate flowers were found. 



Calochortus Nuttallii 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. Gunnisoni 

 shades through the blue shades to the bluish-purple and white.
