tongue. 
Corm ovoid, 5 — 10 lines high, producing offshoots from its base; 
stem 5 — 12 inches long, about one-half of it subterranean; leaves two, 
from near the middle of the stem, apparently basal, unequal, oblong or 
oblong-lanceolate, acute, mottled or green all over, base tapering into long 
clasping petioles; flowers white, frequently tinged with blue or purple, 
on peduncles as long as the leaves; perianth-segments oblong,- recurved, 
not auricled; stigmas linear, becoming recurved, between one and two 
lines long; capsule oblong or obovoid, 5 — 9 lines high. Many plants are 
flowerless consisting of a single leaf with a rather longer petiole. 
This plant grows in moist Woods and thickets, flowering from March 
until May. It ranges from Ontario to Minnesota, south to Georgia^ Ten- 
nessee and Texas. In Iowa the species is quite common and well dis- 
tributed. 
Specimens in the writer’s herbarium are from Johnson, Decatur, 
Shelby, and Emmet counties. The writer has observed the species grow- 
ing in Winneshiek, Van Buren and Page counties. The State University 
herbarium has specimens from Chickasaw, Linn, Polk Mahaska, Cal- 
houn and Pottawattamie counties. Professor Pammel reported the spec- 
ies from Woodbury county; Professor Pink from Payette county; Profes- 
sor Bessey from Payette, Story, Poweshiek, Des Moines and Warren
