156 RYDBERG: STUDIES ON THE 
nodia, a very unfortunate distinction, for in most of the West 
American forms both conditions exist. The filaments of the outer 
stamens are flattened and more or less petaloid. In some cases 
the outermost have noanthers (true staminodia), but often all are 
antheriferous. The present species is therefore placed in both 
species by Kuntze. <Atragene occidentalis differs, however, from the 
_eastern A. Americana in the fact that the staminodia as far as I 
know always are linear, while they are in A. Americana decidedly 
spatulate. A. occidentalis is common from British Columbia and 
the Canadian Rockies south to California and Colorado. 
’ Atragene grosseserrata 
Trailing or climbing over bushes: leaves ternate; petioles 
5-8 cm. long; petiolules 1-2 cm. long; blades broadly ovate, 
oblique, somewhat cordate at the base, 3-4 cm. long, coarsely 
toothed and often somewhat lobed: peduncles 5-10 cm. long: 
sepals lanceolate, about 4 cm. long, 10-13 mm. wide, acute : staml- 
nodia about 18 mm. Jong, decidedly spatulate, a little exceeding 
the stamens: achenes small, sparingly hirsute : tails about 3 cm. 
long, plumose throughout. 
This is closest related to the eastern A. Americana, but the leaves 
are deeper serrate and the sepals are longer, lanceolate, and resem- 
ble more those of A. zenuiloba. From A. occidentalis it differs in 
the spatulate staminodia, the shorter leaflets, which are coarsely 
serrate except the very base. In A. occidentalis the leaflets are en- 
tire or merely crenate above the middle.

Plant trailing : leaves biternate, glabrous, firmer than in the 
two preceding: petioles 5-8 cm. long: secondary leaflets sub- 
sessile except the terminal, which is short-stalked, broadly ovate, 
coarsely toothed with broadly ovate teeth, 3-4 cm. long, abr uptly 
short acuminate at the apex: peduncles over 1 dm. long: sepals 
ovate-lanceolate, about 4 cm. long, acute: staminodia jinear : 
achenes about 5 mm. long, pubescent: tails about 4 cm- long, 
plumose throughout.
