PEDICULARIS CTENOPHORA.
Stem from a thickened caudex, about 3 din. high, glabrous, strict, striate ; leaves numerous, especially at the base, glabrous, rather thickish, pinnately divided into linear-lanceolate serrate segments; spike about 1 dm. long, rather loose ; bracts broadly ovate in outline, pectinately divided ; calyx gibbous above, purple striate, more or less villous-ciliate at the base; corolla purplish ; galea arcuate, produced into an elongated incurved beak; lip very broad, especially the lateral lobes.
It is a near relative of P. contorta, from which it differs in the color of the flowers, the more gibbous and purple-striate calyx, its hairiness at the base and the much larger and broader bracts.
Type : Rydberg, no. 2789, collected on the side of a snowclad mountain, near Lima, Montana, July 29, 1895.
