ows, at elevations of 2000 to 3500 feet. It is also plentiful in- 
meadows in the vicinity of Genesee and Moscow, Latah county. 
It was collected at Lake Waha, near Moscow, by Sandberg, 
MacDougal and Heller, in 1892, while acting as field agents for 
the Department of Agriculture. It is their no. 239, erroneously 
determined by Mr. Holzinger as /rasera speciosa Dougl.,a species 
which belongs to a different section and is easily separated from 
F. fastigiata by having the leaves in fours and sixes instead of 
threes, by their different shape, and by the more leafy stem. 
’ THALESIA PURPUREA 0. Sp. 
Rootstock stout, fascicled or sparingly branched, 5-6 cm. long; 
scales glabrous, broad, acute, prominently veined; scapes stout, 
1-1.5 dm. long, channeled, glandular-pubescent, especially above ; 
calyx equally 5-lobed, glandular-pubescent, prominently 3-nerved, 
the lateral nerves close to the margin, the lobes twice the length 
of the tube, long-acuminate from a triangular base, and reaching 
to the curve of the corolla ;-corolla deep violet-purple, 3 cm. long, 
curved near the middle, glandular-pubescent, lobes broadly oblong 
or obovate, usually notched or sometimes merely rounded, fringed 
with short, glandular hairs, marked with three yellowish veins ; _ 
stamens smooth, the anthers obovate, short, acuminate at the base ; 
style flat; stigma flat, broad, 2-lobed, the lobes obovate, somewhat 
granular-roughened ; ovary glabrous. (Plate 310.) 
The type is no. 3099, collected May 20, 1896, near the coun 
of the Potlatch. The species resembles 7: uniflora in the dried 
state, but is of an entirely different habit. Instead of growing in 
shaded woods, in rich, loose ground, it is found in open, gravelly, 
or rocky ground, where it flourishes best. Specimens found near 
bushes were always dwarfed and stunted. 
The same plant was collected on the rocky hills on the right — 
bank of the Clearwater above Lewiston, by Sandberz, MacDougal _ 
and Heller, in 1892, under no. 11, and determined by Holzinger 
as T. uniflora, in Cont. U. S. Nat. Herb. 3: 245. Although I have 
often collected 7: uniflora in the woods of Pennsylvania, this Idaho — 
plant, when seen growing, was not for a moment considered iden- | 
tical with it.
