and bearded in the throat, 2-lipped corolla, and 2 fertile stamens (the 
upper pair reduced to sterile filaments or wanting). 
* Flowers pedicellate, cymutose or rarely subsolitary in the axils of the leaves. 
+ Calyx-teeth about equal in length, all erect or in fruit curved upward. 
1. H. acinoides Scheele. Minutely pubescent, slender: leaves nearly glabrous, 
slender-petioled, obscurely denticulate; lower ovate, upper oblong, or upper floral 
oblong-linear: upper flowers somewhat capitately, or spicately crowded: calyx 
barely hairy in throat, with setaceous-subulate minutely ciliate teeth: tube of pur- 
ple corolla exserted.—Extending from Arkansas to southern and western Texas. 
++ Two lower calyx-teeth decidedly longer than the three upper. 
++ Leaves entire (rarely obscure denticulations in no. 2). 
2. H. thymoides Gray. Cinereous-pubescent or puberulent: leaves ovate, obtuse, 
petioled; lower little exceeding, upper shorter than the flowers: calyx-teeth of the 
upper lip recurved away from the straightish and moderately longer lower ones: 
corolla little exserted, only 6mm. long. (H. dentata, var. nana Torr. Mex. Bound. )— 
In the mountains beyond the Pecos ( Nealley ). 
3. H. Drummondi Benth. Cinereous-pubescent or puberulent: leaves from oblong 
to linear, obtuse, subsessile, or narrowed at base into a very short petiole, thickish; 
upper mostly rather shorter than the few flowers in their axils: subulate-setaceous 
calyx-teeth at length all connivent and slightly curved upward: the lower nearly 
twice the length of the upper: corolla from 6 to 8mm. long and little exserted to 
12mm. long and twice as long as the calyx.—Common throughout Texas, 
4. H. Reverchoni Gray. A rigid suffruticulose perennial, equably and closely 
leafy to the top, puberulent: leaves elliptical, coriaceous; the floral hirsute beneath 
and on the margins: corolla about twice as long as the strongly hirsute or hispid 
calyx. (H. Drummondi, var. Reverchoni Gray.)—Common in the mountains of western 
Texas. 
ara+ Leaves serrate with salient acute and callous teeth. 
5. H. plicata Torr. Minutely soft-pubescent: leaves approximate, rigid, rhombic- 
ovate or the lower roundish-ovate and uppermost floral oblong, numerously and 
coarsely callous-serrate, conspicuously lineate with the copious strong and straight 
mostly simple veins: lower calyx-teeth erect and moderately longer than the recurved- 
spreading upper ones: corolla pink, 4 to 6mm. long.—Mountains along the Limpia 
and Rio Grande, southwestern Texas, 
* * Flowers sessile or subsessile, verticillastrate in a terminal interrupted spike. 
6. H. ciliata Benth. Erect stem retrorsely puberulent and above mostly hirsute: 
leaves oblong, obtuse, entire, veinless, glabrous or glabrate: bractlets and calyx-tube 
conspicuously white-hirsute; teeth more naked, similar and of equal length: tube of 
rose-purple corolla not exserted, throat hairy at insertion of short included stamens,—

13. SALVIA L. (Saqr.) 
Annuals or perennials, with mostly large and showy flowers in spiked 
or racemed or panicled whorls, 2-lipped calyx, deeply 2-lipped ringent 
corolla (upper lip straight or scythe-shaped, entire or barely notched ; 
lower spreading or pendent, 3-lobed, with middle lobe largest), and 2 
stamens on short filaments jointed with the elongated transverse con- 
nective one end of which (ascending under the upper lip) bears a linear 
1-celled (half-)anther and the other (usually descending) an imperfect 
or deformed (half-) anther or none at all,
