tlie lower oblong, luinutely rugose, tapering into a petiole ; the florul small and 

 bract-like ; the uppermost minute : open tiiyrsoiil-virgute inHorescenuo a loot or so 

 in length, naked : Uowi-rs nearly sessile : the broad upi)er lip of the calyx entire or 

 obsoletely 3-toothed, double tlie length of the triangular subulate teeth of the lower 

 lip: corolla aj)pareutly uhito or i)al(', with very short tube and ample lower lip: 

 stamens and style loiig-exserted. 



Dry hills uiid baiika, S:mta Miubaiu to San Dii-go and eastward, where it is one of tlie various 

 shrubs called Urease-wood. Corolla half an inch or more in length. The open inlloresceuce of 

 this species gives it a peculiar aspect. 



12. LOPHANTHUS, Benth. 

 Calyx tubular-campaindate, 15-nerved, rather oblique, 5-toothed, Corolla with 

 tube not surpassing the calyx : upper lip nearly erect, 2dobed ; the lower some- 

 what spreading and 3-cleft, its broad middle lobe crenate. Stamens 4, exserted, 

 straight ; the upper pair declined and the lower and shorter pair ascending, so that 

 tiio pairs cross : anthers short, 2-celled, tlio cells nearly parallel. — 1 all perennial 

 herbs, mostly coai'sej with ovate and serrate potioled leaves, and small, purplish, 

 violet, or whitish llowias, crowdtid into termiiud spikes. 



A small genus, of two N. K. Asiulic, tlirci; K,a.stiirn Noitli American species, and one in Oregon 

 nnd ('alifornia. L. anis/ilufi, Dentil., the swect-si-ented species of the LJj)per Mississippi region, 

 is in Bohinder's published list of plants growing in the vicinity of San Francisco ; but the fol- 

 lowing was doubtless intended. 



1. L. urticifolius, Benth. Glabrous or nearly so, 4 to 6 feet high: leaves ovate 

 and cordate, coarsely or crenately toothed (2 to 4 inches long, pleasantly scented), 

 rather short-petioled : flower-clusters compacted in a close oblong or cylindrical 

 pedunculate spike: calyx-teeth lanceolate, subulate-acuminate, membranaceous, whit- 

 ish and purplish : corolla light violet-purple. 



Througli the wooded region of the Sierra Nevada, from Mariposa Co. northward, extendino^ to 

 Oregon and to the Kocky Alountains. 



13. SCUTELLARIA, hinn. ' Skui.l-cap. 

 Calyx in flower cauij)anulate, with two entire lips and a gibbous projection on 

 the back, closed and with the dorsal j)r(jjection enlarged after flowering, Ijecoming 

 cus(]ue-shaped, at length splitting to the base, and the upper or casque-shaped por- 

 tion usually falling away. Corolla with an elongated and curved ascending tube, 

 n dilated throat, naked within, an erect arched or galeate u\)\)ov lip (entire or barely 

 notched), with which the lateral lobes belonging to the lower lip appear to be more 

 or less connected ; the anterior lobe (convex or with the sides recurved and apex 

 notched) appearing to form the whole lower lip. Stamens 4, ascending under the 

 upper lip of the corolla ; the lower or anterior pair longer and with one-celled (or 

 half-) anthers ; the posterior pair with 2-celled cordate anthers : these in all ours 

 ciliate or bearded. Upjier fork of the style very small or abortive. Nutlets gran- 

 ulate or tuberculate. Embryo curved! — Bitterish herbs, not aromatic, chiefly 

 perennial ; with single flowers in the axils of the leaves or bracts ; the corolla more 

 commonly blue or bluish. 



A genns of almost 100 species, widely distributed over the world, most largely in temperate 

 regions, well represented in the Atlantic United States, but few in California, none of tliem with 

 racemose or spicate intlorescence. 



S. I.ATEUIFLOUA, Linn., well characterized by its small flowers in axillary one-sided racemes,' 

 extends northwardly across the coutuieut to Oregon, and may therefore reach the northern por-
