4. S. bullata, Benth. Stem retrorsely liispid or hirsute especially on the angles, 

 a foot or two high : leaves ovate or ovate-ohlong, at least the lower more or less 

 cordate, coarsely crenate, obtuse, veiny, sometimes rugose, nearly all petioled (an 

 inch or two long), most of the floral much reduced and shorter than the calyx : 

 flowers usually 6 in the false whorls, these rather distant, forming a narrow much 

 interrupted spike : calyx turbinate-campanulate, mostly hirsute or villous with 

 widely spreading hairs ; the teeth triangular-ovate and subulate-cuspidate, rigid : 

 lower lip of the corolla fully as long as the tube, much larger than the upper. — 

 S. bullata, & S. Californica, Benth. in DC. S. Nuttallii, var. leptostachya, Benth. 

 PL Hartw. 331. 



Mendocino Co. to San Diego and Fort Mohave ; apparently a very common as well as wide- 

 spread and variable species ; the pubescence of the leaves often soft. Lower lip of the corolla 4 

 or 5 lines long, the upper 2 or 3. 



S. palustris, Linn., in some of its forms occurs in Oregon, and may reach the northern bor- 

 ders of California. 



* * Tube of the red corolla much surpassing the calyx, over half to three fourths of 

 an inch long : flowers mostly 6 in the false whorls. 



5. S. Chamissonis, Benth. Stem 2 to 5 feet high, stout, mostly rough-hispid 

 with rigid retrorse bristles, at least on the angles : leaves (2 to 5 inches long) oblong- 

 ovate and mostly a little cordate, crenately serrate, usually villous or hirsute above 

 and villous-tomentose beneath, nearly all petioled; all but the lowest floral ones 

 shorter than the loosely interrupted spicate flowers : calyx tubular-campanulate ; its 

 triangular-ovate teeth cuspidate-tipped : corolla rose-red ; its tube twice the length 

 of the calyx ; the lips pubescent outside. 



AVet grounds ; common around San Francisco Bay. 



S. ciliata, Dough, a smoother and thinner-leaved species of this section, with the lower 

 flowers in the axils of ordinary leaves, belongs to the coast of Oregon and northward, perhaps 

 also in the northern part of California, 



S. coccinea, Jacq., a handsome Mexican species, with a tubular scarlet corolla, occurs in 

 Arizona and may perhaps reach the lower borders of California. 



18. TRICHOSTEMA, Linn. Blue-curls. 



Calyx campamdate, in ours little oblique and almost equally 5-cleft. Corolla with 

 short or rather slender tube and almost equally 5-parted limb, which is gibbous or 

 oblique in bud ; the lobes oblong and similar. Stamens 4 : filaments long and 

 capillary, spirally coiled in the bud, long-exserted from the upper side of the corolla, 

 sometimes monadelphous at base : anther-cells divergent or divaricate, and soon 

 confluent. jSTutlets coarsely rugose-reticulated. — Sweet-aromatic herbs or suffrutes- 

 cent plants (all Xorth American) ; with entire leaves, and blue or purple corolla 

 and stamens. — The two species of the Atlantic United States have scattered and 

 pedunculate flowers, with a very oblique and unequally 2-lipped calyx; the inter- 

 mediate T. Arizonicum has the loose inflorescence of the foregoing with the 

 almost regular calyx of the western species, all which have very short axillary 

 peduncles, bearing several or numerous flowers in dense and mostly unilateral 

 cymose clusters. 



* Corolla hardly if at all surpassing the calyx. 



1. T. oblongum, Benth. Annual, soft-villous : stem a span or two high, 

 diffusely branching, equally leafy to the top : leaves oval-oblong, thin, contracted 

 at base into a short petiole, much exceeding the small and dense cluster of nearly 

 sessile flowers : calyx very villous, deeply 5-parted, the lobes lanceolate-subulate. —
