Trkhostema. VERBENACEJE. 607 



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

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

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



* % Corolla vjith slender tube exceeding the calyx : cymose flower-clusters disposed to 

 fork and to become raceme-like in age. 



2. T. laxum, Gray. Ann^ial, minutely soft-pubescent, aBout a foot liigli, 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 flowers 

 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-blue. 



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

 a foot or mure in height, with virgate stem or branches very leafy : leaves nuich 

 longer than the internodes, 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 Oregon. 



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, Ilosemary-like, 

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

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

 (of a foot or 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 ? or 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, difl'ering from Labiatce mainly in the ovary and fruit, whicli 

 is undivided and 2 - 4-celled, at maturity either dry and splitting into as many 

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

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

 tion. Stamens 4, didynamous. 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 jilternate, with- 

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

 Labiatce. Flowers perfect : inflorescence various. 



An order of moderate extent in tropical and warm-temperate regions, a few f^^fjj;''^^'^l 

 the cool-temperate, of no striking sensible properties or econonucal "^n^o^'tance exce ng _^ t 

 American Verbenas so common in ornamental cultivation, and a lew species ol Liuilaaa. Hit 

 Californian representation of the order is feeble. 



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

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