16. S. ParryiGray. Low, much branched: leaves ovate-oblong, mostly with trun- 
cate base, obtuse, crenate, short-petioled, tomentulose-canescent, as are the branch- 
lets: flowers interruptedly spicate, several in each cluster: calyx densely woolly 
with white branched hairs: corolla (blue?) short and small, slightly pubescent: con- 
nectives free (S. spicata? Torr. Mex. Bound., not Rem. & Sch.).—‘‘Apache Springs on 
the Rio Grande.” 
17. S. spicata Rom. & Sch. Canescent with minute and dense pubescence, very 
leafy: leaves small, lanceolate-oblong, obtuse, minutely and closely crenulate, sub- 
sessile, upper face soon glabrate and rugose-venulose: calyx woolly-tomentose : 
corolla 6 to 8 mm. long, blue or purple.—Runnels County (Nealley). 
18. S. ballotzeflora Benth. Shrub 6 to 24 dm. high, tomentulose-canescent: leaves 
ovate or somewhat oblong, truncate-cuneate or subcordate at base, crenate, reticu- 
late-veiny, mostly rugose, slender-petioled, glabrate and green above, white be- 
neath: flowers in short and rather dense simple racemes in axils of upper ordinary 
leaves, 8 mm. long: calyx pendulous in fruit and with ampliate reticulate-veiny 2 
or 3-lobed limb exceeding the tube of the small bluish or purple corolla.—Southern 
and western Texas. ‘‘Majorano” of the Mexicans. 
14. MONARDA L. (HoRSE-MINT.) 
Odorous erect herbs, with entire or toothed leaves, rather large flow- 
ers in a few whorled heads closely surrounded with bracts, tubular 
elongated 15-nerved nearly equally 5-toothed calyx usually hairy in the 
throat, elongated strongly 2-lipped corolla (lips linear or oblong, some- 
what equal; upper erect, entire or slightly notched; lower spreading, 
3-lobed at apex, middle lobe narrowest and slightly notched), 2 elon- 
gated ascending stamens inserted in throat of corolla, and linear anthers 
with divaricate cells confluent at the junction. 
* Stamens and style exserted beyond the linear straightacute upper lip of the corolla : head 
solitary and terminal or sometimes 2 or 3: leaves acutely more or less serrate. 
1. M. fistulosa L. Smoothish or downy, 6 to 15 dm. high: leaves ovate-lanceo- 
late, the uppermost and outer bracts somewhat colored (whitish or purplish): calyx 
very hairy in the throat: corolla 2.5 cm. long or more, purple or purplish dotted, 
smooth or hairy.—Dry soil, throughout Texas; where also occurs var. MOLLIS Benth., 
in which the corolla is flesh-color to lilac, glandular, its upper lip hairy outside or 
more bearded at tip; leaves paler, soft-pubescent beneath; calyx-throat mostly filled 
with dense beard. ‘ Wild bergamot.” 
** Stamens not exceeding tha faleate upper lip of the short corolla: head axillary or in- 
terrupted spicate : leaves lanceolate or oblong, sparsely serrate, tapering into the petiole. 
2, M. punctata L. Perennial, minutely downy, 6 to 9 dm. high: leaves lanceolate : 
bracts lanceolate, blunt, obtuse at base, sessile, yellowish and purple: teeth of the 
downy calyx short and awnless, rigid, soon spreading: corolla nearly smooth, yel- 
lowish, the upper lip spotted with purple, notched at apex, the tube scarcely ex- 
ceeding the calyx.—Sandy ground, extending from the Atlantic region to southern 
and western Texas. ‘‘Horse-mint.” A Texan form is var. LASIODONTA Gray, with 
throat and teeth of calyx densely villous. 
3. M. citriodora Cerv. Annual, 3 to 9dm. high: bracts narrowly oblong, whitened 
or purple-tinged, their slender awned tips spreading or recurving: calyx-teeth slen- 
der, usually spreading, the tube mostly glabrous: corolla white or pinkish, not 
spotted.—Plains of Texas. 
4, M. clinopodioides Gray. Like the last, but bracts green or greenish, erect,
