very variable in different parts of the stem: the lower ones 
more or less pinnatifid, with few, linear-oblong segments, 
some of them again divided or. incised, which, however, is 
by no means the case in all our specimens: the upper ones 
gradually more entire, and at length altogether linear-lan- 
ceolate. The flowers form lax, terminal racemes: the 
pedicels are slender. . The calyx-tube.is cylindrical, taper- 
ing at the base: the éeeth as long as the tube of the corolla, 
subulate, straight. Corolla, brilliant, purplish-blue: the 
upper lip of two small, reflexed, subulate, hairy teeth ; 
lower of three large lobes, of which the middle lobe is much 
the largest, obcordate: the lateral ones spreading, dimidi- 
ato-obovate. Anthers included, all of them bearded.
