20 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 Labiate. ‘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. sazxatilis, Riddell: those of the elongated flower 
branches scarcely half an inch long. Achenia strongly tuber- 
culate. Root apparently annual. 
145. Satvia azurea, Lam. Houston. May to September. 
146. Hypris raprata, Willd. Houston. September. 
147. Puysosteera Vireiniana, Benth., var. foluis ovalibus 
oblongisve subdenticulatis. _(Dracocephalum  variegatum, 
Vent., Ell.) Wet prairies west of the Brazos. July. 
148. P. Virerntana, var. foliis lanceolatis argute serratis. 
Dry, sandy soil. Houston. September. 
149, TricnostemMA DicHoromum, Linn. September. 
150. Tevcrium Cupensr, Linn., Benth. Lab. P 668. 
Galveston Island. April, May. 
151. Monarpa Linpuerimert, (n. sp.): caule glabro super- 
ne piloso subsimplici ; foliis ovatis acuminatis subcordatis 
erosse serratis glabris glandulosis margine scabris, petiolis 
brevibus basi pilosis; bracteis acuminatis integris capitulum 
laxum subsequantibus ; calycibus glandulosis, dentibus subu- 
latis diametrum tubi subequantibus, fauce villosa; corolla 
glandulosa et villosa. — Prairies and margin of woods, in 
clayey soil. April to June, and again in October. — According 
to Mr. Bentham’s view, this would probably be deemed a 
variety of M. clinopodia. 
152. M. puncrara, Linn. Houston. July.
