cordate at base, obtuse, crenate, 2 or 3 inches long; flowers several or many in capitate 
clusters which usually exceed the small floral leaves and form an interrupted spike; corolla 
white with purple dots on the lower lip. 
3. S. pycnantha, Benth. Very hirsute, with long and mostly soft spreading hairs, 
not white, two feet high or more; flowers in a dense cylindraceous naked spike (an inch 
or two long), exceeding the small bract-like floral leaves except in the lowest and some- 
‘times rather distant clusters; corolla white or cream-color, with purple onthe lower lip. (?) 
* * Corolla purple, the upper lip hairy on the back ; pubescence somewhat hispid; no tomentum. 
4, S&S. bullata, Benth. Stem retrorsely hispid, especially on the angles, 1 to 3 ft. 
high; leaves somewhat rugose, nearly all petioled, 1 to 2 inches long; flowers usually 6 in 
‘the false whorls, these rather distant, forming a narrow interrupted spike; lower lip of 
the corolla fully as long as the tube, 4 or 5 lines long, the upper half as long.—Variable. 
*** Tube of the rose-red corvlla twice as long as the calyx, 6 to 9 lines long. 
5. S&S. Chamissonis, Benth. Stem 2 to 5 ft. high, stout, mostly rough-hispid, with 
retrorse rigid bristles; leaves 2 to 5 inches long; lips of the corolla pubescent outside.—

13. TRICHOSTEMA, L. Buve-curzs. 
Calyx campanulate and almost equally 5-cleft. Corolla with short or slender tube and 
an almost equally 5-parted limb. Stamens with long capillary curved filaments, some- 
times cohering at the base.—Strong scented herbs; with entire leaves, and blue or purple 
corolla and stamens. In ours the flowers are in cymose axillary clusters, somewhat 
raceme-like in age; the corolla about 5 lines long, and the stamens twice as long or more. 
1. T. laxum, Gr. Minutely soft pubescent, about a foot high, simple or loosely 
branched from the base; leaves rather distant, lanceolate or oblong-lanceolate, tapering 
into a petiole at the base; flower clusters distinctly peduncled, usually forked and in 
age equaling the leaves; corolla almost smooth. 
2. T. lanceolatum, Benth. Leafy; leaves much longer than the internodes, lance- 
olate or ovate-lanceolate, sessile by a broad base, 3-5-nerved, an inch or less long; flower 
clusters nearly sessile, short, one-sided; corolla somewhat pubescent.—Its odor sickeu-

Orver 46. VERBENACEZ. 
Herbs or shrubs differing from Labiate mainly in the ovary and fruit, which is undi-

or drupaceous, containing as many little stones.
