Trichostema. VERBEXACE-E. 607 



Wooded portion of the Sierra Nevada, from Mariposa to Shasta Co., and in Oregon. Plant 

 with a pungent and very pleasant aroma. Leaves barely an inch long ; the pinnate veins ascend- 

 ing. Corolla barely 3 lines long, and the stamens 2 Hues lunger. 



* * Corolla with slender tube exceeding //,, calyx: cyi nose flower-clusters disposed to 

 fork and to become raceme-like, in age. 



2. T. laxum, • tray. Annual, minutely soft-pubeseent, about a foot high, simple 

 or loosely branched from the base : leaves rather distant, lanceolate and oblong- 

 lanceolate, acute or acuminate, rather obscurely pinnately veined (an inch or two 

 long), tapering at the base mostly into a slender petiole : axillary cymose clusters 

 distinctly peduncled, usually forked and in age equalling the leaves; the Hewers 

 pedicelled: calyx-lobes ovate-triangular and equalling the tube: corolla almost 

 glabrous, 3 or 4 lines long, and the stamens half an inch longer. — Proc. Am. 

 Acad, vii. 387. 



Dry ground, from Marin Co. to Humboldt Co. ; apparently a rather common species. Flowers 

 indigo-blui . 



3. T. lanceolatum, Benth. Annual, cinereous-pubescent or villous, a span to 

 a foot or more in height, with virgate stem or branches very leafy : leaves much 

 longer than the intemodes, lanceolate or ovate-lanceolate, sessile by a broad base, 

 gradually acuminate, traversed by 3 to 5 strong and almost parallel nervose veins 

 or ribs (an inch or less long): cymose axillary clusters nearly sessile, short, one- 

 sided : calyx-lobes ovate-lanceolate : corolla somewhat pubescent, half an inch long, 

 the tube almost filiform. 



Dry ground, chiefly in the western part of the State, rather common from Los Angeles Co. 

 northward and in I Iregon. 



4. T. lanatum, Benth. Shrubby below, 2 or 3 feet high, very leafy : branches 

 and foliage canescently puberulent or tomentulose and glabrate with age : leaves 

 very narrowly linear, obtuse, 1-nerved and with revolute margins, Rosemary-like, 

 many fascicled in the axils; the floral ones mostly small and bract-like: Howei 

 clusters glomerate and sessile, numerous in a virgate interrupted purple-woolly spike 

 (of a foot ot less in length): corolla very woolly, nearly an inch Long, and the stamens 

 and style an inch or two longer. — Torr. Bot. Mex. Bound, t. 40. 



Rocky ledges, Monterey for Santa Barbara to San Diego Co. Flowers violet. Very striking 

 for the purple-woolly spike and long capillary stamens and style. 



Order LXXIV. VERBENACE^. 



Herbs or shrubs, differing from Labiata mainly in the ovary and fruit, which 

 is undivided and 2- l-celled, al maturity either dry and splitting into as many 

 1 -seeded millets, or drupaceous containing as many little stones. — Calyx persistent. 

 Corolla either bilabiate or merely somewhat irregular; the lobes imbricate' in aestiva- 

 tion, stamens I, didynanmus. Style single: stigma entire or 2-lobed. Solitary 

 ovule erect or ascending and anatropous. Seed with a straight embryo, its radicle 

 inferior, and no albumen. Leaves opposite or whorled, very rarely alternate, with- 

 out stipules, sometimes aromatic, but not glandular-punctate ill the manner of most 

 •'. Flowers perfect: inflorescence various. 



An order of moderate extent in tropical and warm-temperate regions, a few, chiefly weeds, in 

 the cool-temporal ol no triking sensible propertii or economical importance, excepting the 

 American Verbeno ornamental cultivation, and a few species of Lantana. The 



(.'alifornian representation • >! the order is feeble. 



1. Verbena. Fruit of 4 united nutlets. Calyx tubular or prismatic. 

 ■J. Lippia. Fruit of 2 united nutlets. Calyx 2-cleft
