Lippia. VERBENACE^E. 609 



* * Stem erect : spikes slender-cylindrical, densely-floivered ; the flowers and fruit 



overlapping : bracts short. 



4. V. hastata, Linn. Perennial, minutely pubescent : stem stouter, 3 to 6 feet 

 high : leaves oblong- lanceolate, gradually acuminate, coarsely or incisely serrate, 

 petioled, some of the lower ones commonly hastate-3-lobed : spikes numerous in a 

 terminal panicle, 2 to 4 inches long : corolla blue, 2 lines long, and the limb as 

 broad. V. paniculata, Lam., the name given to the form, not uncommon, which 

 has no lobes to the leaves. 



Marshes on the Lower Sacramento, according to Torrey, Bot. Wilkes Exp. 403. Probably else- 

 where in the State. 



* * * Stems spreading or merely ascending : s%)ikes not filiform. 



5. V. prostrata, E. Brown. Soft-hirsute or villous : stems at first erect or 

 ascending, a foot high, at length widely branched and diffuse, rarely prostrate : 

 leaves obovate, ovate, or oblong, with cuneate base tapering into a margined petiole, 

 sharply serrate, incised, or 3 - 5-cleft : spikes solitary or panicled, rather slender but 

 dense when in flower, becoming 4 to 10 inches long, hirsute or villous : bracts 

 subulate, not longer than the calyx : corolla violet or blue, 2 lines long. Ait. 

 Hort. Kew. ed. 2, iv. 41. V. lasiostachys, Link; Hook. & Arn. Bot. Beechey, 156. 



Common in dry ground through the western parts of the State. Root probably perennial. 

 Plant very variable. From Jamuel Valley, below San Diego, Dr. Palmer sends a more upright 

 and thickish-spiked plant, which might be a cross between this and V. strida, if the latter were 

 California!! ; or perhaps it has some V. hastata in it. 



6. V. bracteosa, Michx. Perennial, hirsute, a span to a foot high, at length 

 diffusely much branched : leaves cuneate-oblong or obovate, pinnately incised or 

 3-cleft and coarsely toothed ; the lower narrowed into a short margined petiole ; the 

 uppermost passing into bracts : spikes terminating the branches, thickish, rather 

 dense, and squarrose with the rigid lanceolate or linear acuminate and sparsely his- 

 pid foliaceous bracts, which surpass the flowers : corolla purplish or blue, small and 

 slender. Hook. Bot. Mag. t. 2910. 



Near Monterey, in alkaline soil, Bolander: a peculiar and rigid form, with bracts or bract-like 

 leaves far down the stem. The ordinary form occurs in Oregon, and extends to the Atlantic States. 



2. Flowers more showy : spike at first short and capitate : connective of the anthers 

 of the longer stamens tipped with a yland. 



7. V. ciliata, Benth. Low and diffuse, apparently annual, villous-hirsute ; or the 

 leaves somewhat strigose-hispid, once or twice 3-parted or cleft, short-petioled ; the 

 lateral divisions commonly 2-lobed and the middle one 3-5-lobed or incised: bracts 

 lanceolate-subulate, shorter than the calyx : tube of the latter oblong ; the teeth 

 rather short-subulate, nearly equal: corolla "blue," or purple; the tube hardly 

 twice the length of the calyx. PI. Hartw. 21 ; Schauer in DC. Prodr. xi. 553. 



Tantillas Mountains on the southern borders of the State (Palmer), a form with rather coarsely 

 cleft leaves : extends through Arizona (Palmer, Lieut. Wheeler, &c.), to W. Texas and Mexico. 



V. BIPINNATIFIDA, Schauer ((rlandularia bipimiat.ifida, Nutt.), from Colorado to Texas, is 

 certainly perennial, and lias much longer and slender bracts and calyx-teeth, the latter very 

 unequal. 



2. LIPPIA, Linn. 



Corolla somewhat funnelform or salverform ; the limb either bilabiate (upper lip 

 entire or 2-lobed, lower 3-parted), or 4-cleft and merely oblique. Stamens 4, in- 

 cluded. Stigma capitate or oblique. Ovary 2-celled, in fruit forming 2 one-seeded 

 nutlets. Herbs or shrubs, of various aspect : the foliage sometimes aromatic, as in 

 L. citriodora, the sweet Verbena-shrub of the gardens, native of S. America, to 

 which most of the species belong.
