which are ovate-oblong and always white, while in T. cernuum 
they may be elliptie, oval or ovate, acute, and white or pink. 
The anthers and capsule of T. declinatum are yellow. Like 
many species of Trillium, it varies greatly in size. 
Ohio and southern Michigan to Missouri and Minnesota. 
- The following specimens from Mo. Bot. Gard. Herb. show 
interesting peculiarities: 
Taughannock Falls, Ithaca, N. Y., 14 May, 1892, Н. von 
Schrenk, This specimen agrees with 7. declinatum except 
that the capsule is purple, the peduncle appears to be erect, 
and the petals are lanceolate. It may be a white derivative 
from T. erectum. Fountaindale, Winnebago Co., Ill., 1867, 
М. 8. Bebie 8229; Armstrong, Emmet Со., Та., 13 Мау, 1899, 
R. I. Cratty. These specimens differ from Т. declinatum in 
having purple anthers. The former also has narrowed petals. 
These are perhaps unit variations, and they show that the 
coloration of petals, anthers, and capsule may vary indepen- 
dently, but in some specimens certain organs are only partly 
colored.

The main peculiarities of this species were mentioned under 
Т. declinatum. Its foliage is closely similar to that of other 
members of the erectum group.

This species is somewhat isolated from its nearest rela- 
tives by a number of peculiarities. The leaves are ovate,
