* Herbs, minutely pubescent or smoothish, not canescent or white-woolly: flowers capitate or 

 spicate : leaves slender-petioled. 



H. radiata, W^illd. Stems tall, mostly simple from a perennial root : leaves ovate-lan- 

 ceolate, toothed, and with entire long-tapering base : axillary peduncles usually shorter 

 than the leaf, bearing a many-flowered soft-puberulent capitate glomerule which is mostly 

 shorter than its involucre of several lanceolate obtuse whitish bracts : calyx campanulate : 

 its teeth lanceolate-subulate and rigid : corolla white, purple-dotted. — Spec. iii. 84 ; Poit. 

 Ann. Mus. vii. t. 27. Clinopodium rugosum, L. — Low ground, from North Carolina towards 

 the coast to Texas. 

 H. peotinata, Poit. Stem tall, commonly rough on the angles, branching : leaves long- 

 petioled, ovate, serrate : flowers sessile in small capitate glomerules which become unilateral 

 in age, these subulate-bracteate and crowded in a spiciform interrupted thyrsus : fruiting 

 calyx with short-oblong tube a line in length, densely short-villous in the throat, longer than 

 the erect setaceous teeth : corolla very small. — Ann. Mus. vii. 474, t. 30 ; Benth. in DC. Prodr.

 H. spicata, Poit. Stem tall from an annual root, branching, rough-angled : leaves ovate, 

 acuminate, unequally serrate : flowers in small capitate glomerules, which are short- 

 peduncled or sessile, and form interrupted and often paniculate terminal racemes or spikes : 

 calyx cylindrical, with base somewhat inflated in fruit, then much exceeding the bracts ; 

 teeth subulate-setaceous, short, strict. — S. Florida. Ann. Mus. Par. vii. 474, t. 28, fig. 2 ; 

 Benth. in DC. Prodr. xii. 121.— (Mex., S. Am.) 



H. polystachya, HBK., allied to this, is said in Bot.Beechey, 156, but doubtfully, to have 

 been collected in California. 



# * Shrubby, at least the calyx and short pedicels white-woolly with many-branched implexed 

 hairs: bracts inconspicuous. 



H. Emoryi Torr. Shrub 5 feet high, lavender-scented, furfuraceous-canescent : leaves 

 ovate, crenate (inch or less long), rather slender-petioled: flowers on pedicels about the 

 length of the lanate-furfuraceous calyx, in axillary short-peduncled cymes, and in denser 

 somewhat paniculate clusters at the end of the branchlets: corolla violet, only 2 lines 

 long. _ Bot. Ives Colorad. Exped. 20 ; Gray, Bot. Calif, i. 591. II. lanata, Torr. Bot. Mex. 

 Bound. 129, excl. syn. — Arid region, S. E. California and Arizona. (Adjacent Mex.) 

 H. Albida, HBK. of Mexico, not yet found within our borders (although a form of H. 



Emoryi has been mistaken for it), has more oblong leaves, and sessile glomerules crowded in 



terminal naked spikes. 



H. lanifl6ra, Benth. Bot. Sulpb. t. 20, a remarkable species, with rotund and angulate- • 



dentate glabrous leaves on slender petioles, open cymes on filiform peduncles, and very 



densely long-woolly calyx (the wool dendritic-branched), is known only from Cape San Lucas, 



in Lower California. 



H. tephr6des, Gray, Proe. Am. Acad. v. 164, from the same place, collected by Xantus, 



is minutely canescent, except the furfuraceous calyx, and has subsessile lanceolate leaves, 



and paniculate inflorescence.
