34” wide or fests concave; bracts 3; flowers 3-4, sepals 3-34” long, 
9)? wide, rowly ovate, obtuse, the outer ones dark-veined; 
pedicels 5 fe filaments as long as the sepals; bulblets red; 
ovary not crested. This appears to be a form of A. Canadense. 
Found on the Colorado-Wyoming line.

2A2B. Pedicels not evidently sinuous, mostly stout, seldom 
more than 9’’ long, often less; plants rarely if ever bulbif- 
erous. These plants probably all belong to one species. 
Stems rather low, rarely 1° high. 
57. A. mutabile Michx. I'l. 1 195. Bulbs coarsely fibrous; 
capsules crestless; leaves usually 3, about 2”) broad, flat. shorter 
than the pedunele; flowers light-colored, 2-4” long; sepals thin 
and Jax in fruit, ovate to narrowly lanceolate, obtuse to acutish. 
From North Carolina. Nebraska, New Mexieo and southward. 
A. arenicola Small Torr. Bull. 27 276. Pedicels 3-5” long, 
slender; flowers 10-30, deep-pink; sepals linear to narrowly Loe 
ceolate, 2” long, very delicate; filaments dilated at base; eapoule 
not crested. This is probably a slender form of A. mutabile.

58. A. Nuttallii Wats. Proc. A. A. 14 227: Bulbs small, 
little over 6” long; peduncles about 6’ high; sepals about 3” long 
(in mine 2” long), ovate to ovate-lanceolate, rather rigid and 
acute, often red; capsule not crested; leaves very narrow; bulb 
coats rather chestnut-brown, with very dense and fine meshes 
which split up into threads on their upper edge, but below gen- 
erally remain solid. This seems to have been confused with A. 
reticulatum or else passes into it by insensible gradation. Kan- 
sas to Colorado and south ward,
