228 Engelmann and Gray, 
&c. near Houston. Flowering through the summer. Dr. 
Engelmann has likewise collected the smaller variety at the 
Hot Springs, in Arkansas. Fruiting specimens of this well- 
marked species also exist in Drummond’s Texan Collection, 
(No. 209, Coll. 3,) but we find no allusion to it in Bentham’s 
fine Monograph of the Labiatz. The smaller forms might be 
confounded with S. parvula, but even the floral leaves are 
distinctly petioliate, broadly triangular-ovate, or cordate, and 
more or less crenate-toothed ; all are shorter than the corolla, 
which is three-fourths of an inch long ; the uppermost scarcely 
exceeding the calyx. The cauline leaves are from one to 
nearly two inches in length, and considerably resembling those 
of S. saxatilis, Riddell: those of the elongated flower 
branches scarcely half an inch long. Achenia strongly tuber- 
culate. Root apparently annual.
