602 LABIATE. Audibertia. 



the lower oblong, minutely rugose, tapering into a petiole ; the floral small and 

 bract-like ; the uppermost minute : open thyrsoid-virgate inflorescence a foot or so 

 in length, naked : flowers nearly sessile : the broad upper lip of the calyx entire or 

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

 lip : corolla apparently white or pale, with very short tube and ample lower lip : 

 stamens and style long-exserted. 



Dry hills and banks, Santa Barbara to San Diego and eastward, where it is one of the various 

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

 this species gives it a peculiar aspect. 



12. LOPHANTHUS, Benth. 



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

 tube not surpassing the calyx : upper lip nearly erect, 2-lobed ; 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 

 the pairs cross : anthers short, 2-celled, the cells nearly parallel. Tall perennial 

 herbs, mostly coarse ; with ovate and serrate petioled leaves, and small, purplish, 

 violet, or whitish flowers, crowded into terminal spikes. 



A small genus, of two N. E. Asiatic, three Eastern North American species, and one in Oregon 

 and California. L. anisntus, Benth., the sweet-scented species of the Upper Mississippi region, 

 is in Bolander'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. 



Through the wooded region of the Sierra Nevada, from Mariposa Co. northward, extending to 

 Oregon and to the Rocky Mountains. 



13. SCUTELLARIA, Linn. SKULL-CAP. 



Calyx in flower campanulate, with two entire lips and a gibbous projection on 

 the back, closed and with the dorsal projection enlarged after flowering, becoming 

 casque-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, 

 a dilated throat, naked within, an erect arched or galeate upper 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. Upper fork of the style very small or abortive. Outlets 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 genus of almost 1 00 species, widely distributed over the world, most largely in temperate 

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

 racemose or spicate inflorescence. 



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

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