 ing conspicuously shorter than the primary stem, sometimes slightly elongating 

 and bearing reduced flowers; leaves lanceolate or lance-attenuate, crenate- 

 dentate, the teeth subappressed ; bracts glabrous, dark green, the lower

 ing-ascending crowded teeth (5 mm. long) much exceeding the appressed upper 

 ones; calyx glabrous, green, often black-striate ; corolla yellow, about 1.5 cm. 

 long, its tube straight, the teeth of the upper lip depressed, rounded, violet, the 

 lateral lobes of the lower lip with a black spot at base. (S. minor Ehrh.)

 short branches, green ; leaves oblong or linear-oblong, obtuse, crenate-dentate, 

 scabrous above, minutely pilose beneath ; bracts scabrous, mostly shorter than 

 the mature calyces, deltoid-ovate, laciniate-dentate, the lower deltoid-lanceolate 

 teeth 3-4 mm. long; calyx glabrescent, the margins ciliate, in fruit 1.3-1.9 cm. 

 long, greenish-yellow, often tinged with bronze; corolla yellow, 1-1.2 cm. long.

 blackened in drying. 



4. R. stenophyllus (Schur) Schinz & Thellung. Stems 2-6 dm. high, black- 

 lineolate, commonly with long arcuate-ascending branches with axillary fascicles ; 

 leaves linear- to oblong-lanceolate, crenate-dentate, the teeth subappressed ; 

 firacts glabrous, purple-tinged, the lower like the foliage leaves and subtending 

 the remote flowers ; upper bracts subapproximate, triangular, equaling the calyx, 

 their teeth lance-deltoid; calyx purple-tinged, glabrous, in fruit 1.5 cm. long; 

 corolla 1.5 cm. long, canary-yellow, turning brownish, the teeth of the upper lip

5. R. Kyr611ae Chabert. Stems 3-7 dm. high, green, not black-lineolate, 

 simple, or commonly wit h long ascending branches without axillary fascicles ; 

 leaves oblong-lanceolate, scabridulous, the teeth subappressed or slightly spread-
