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

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



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

 fork and to become raceme-like in age. 



2. T. laxum, Clray. Annual, niinntoly soft-pulicscnnt, about a foot higli, simple 

 or loosely branched from tlie 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 e(|ualling the leaves ; the flowere 

 pedicelled : calyxdobes ovate-triangular and equalling the tube: corolla almost 

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

 Acad. vii. 387. 



Dry OT-ound, from Marin Co. to Humboldt Co. ; apparently a rather common species. Flowers 

 indigo-lilue. 



3. T. lance olatum, Bonth. Annual, cino.reous-pul)osoent or villous, a span to 

 a foot or more in height, with virgato stem or bninchcs very leafy : leaves much 

 longer than the internodcs, lanceolate or ovatn-lancoolate, Rossilo 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 conunon 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, Jiosemary-like, 

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

 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. Max. Bound, t. 40.

Order LXXIV. VERBENACEiE. 



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

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

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

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

 tion. 'Stamens 4, didynamous. Stylo single : stignm entire or 2-lobcd. 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 in the manner of most 

 Labiativ. Flowers perfe(;t : inflorescence various. 



An order of moderate extent in tropical and warm-tempemto regions, a few, chiedy weeds, in 

 the c()ol-tenipomt<s of no striking sensible properties or cconomii-nl importniicp, excepting the 

 American Verbenas so conunon in ornamental cultivation, and a few species of Lnnlana. The 

 Californian representation of the order is feeble. 



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

 2. Llppia. Fruit of 2 united nutlets. Calyx 2-clert.
