LILIACEZ. 
Allium cernuum Roth, in Roem. Arch. Bot. i, pt. 3, 40 (1798), 
All specimens of this species, in the National Herbarium, from the Rocky Mountain 
region have narrow and apparently channeled leaves; those from the eastern United 
States have broad and flattened leaves. I do not know which form should be 
regarded as the typical one, as I have not seen the original description. The descrip- 
tion and figure in Curtis’s Botanical Magazine agree with the specimens of this col- 
lection and, as far as I can judge, with all from the Rocky Mountain region. There 
the leaves are represented as half-round and channeled, not as “sharply keeled” as 
they are described in Gray’s Manual, ed.6. In mine they are not keeled at all.

Allium geyeri Wats. Proc. Amer. Acad. xiv, 227 (1879). 
This, as also the next, is described as having crested capsules. The crests are, 
however, easily overlooked, being 2 small lobes on each valve, near the top. Over- 
looking these, I named this 4. mutabile and the next A. nuttallii, which they resem- : 
ble, respectively, in habit,
