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

 rate or crenate ; the teeth somewhat 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. 209; Stev. Monogr. 44, t. 15; Reichenb. Iconogr. iv.

 sometimes bidentulate: calyx 5-toothed: capsule acuminate, usually double the length of the
