P. SCOpulorum. Glabrous, except the arachnoid-lanate dense oblong spike : calyx-teeth 

 triangular-subulate, entire, membranaceous, very much shorter than the tube : galea of 

 tlie reddish-purple (three-fourths inch long) corolla with its somewhat produced apex 

 obliquely truncate, edentulate or produced on each side into an obscure triangular tootli : 

 otherwise as the following. — P. Sndetica, var.. Gray in Am. Jour. I.e. — Colorado Rocky

 a. Galea falcate-incurved and with somewhat produced bidentulate summit. 



P. Sudetica, ^AT^illd. Glabrous, or the spike commonly hirsute-villous or lanate : stem a 

 span high, few-leaved : leaves simply pinnately-parted ; divisions lanceolate, incisely ser- 

 rate or crenate ; the teeth somewdiat cartilaginous : spike dense, mostly short : calyx- 

 teeth lanceolate or linear, little shorter than the tube, serrulate: corolla purple (9 or 10 

 lines long) ; galea longer than the erose-crenulate lobes of the lip; the tooth at the lower 

 side of truncate apex on each side conspicuous and cuspidate, sometimes shorter and 

 triangular-acuminate. — Spec. iii. 200; Stev. Monogr. 44, t. 15; Reichenb. Iconogr. iv.
