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



overlap [ling : bracts short. 



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

 high : leaves oblong-lanceolate, gradually acuminate, coaTsely 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. paiiicidala, 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 : spikes not filiform. 



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

 ascending, a foi >t 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. 

 Ilort. Kew. ed. 2, iv. 41. V. lasiostachys, Link ; Hook. & Am. 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 8 more upright 

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

 Californian ; ur perhaps it has some V. luislata in it. 



G. 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 capitati : connective of the anthers 

 of the longer stamens tipped with a gland. 



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 

 twico the length of the calyx. — PI. Hartw. 21 ; Sehauer in DC. Prodr. xi. 553. 



Tantillas Mountains on tin" southern borders of the Stati i, a form with rather coarsely 



cleft leaves : extends through Arizona {Palmer, lAtut. Wheeler, <tc), to W". Texas and Mexico. 



V. Bii'iNNA tiiii>\, Sehauer [Glandularia bipinnatifida, Nntt.), from Colorado to Texas, is 

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

 unequal. 



2. LIPPIA, Linn. 

 Corolla somewhat funnelform or salrerform : the limb either bilabiate (upper lip 

 entir ■ 2-lobed, lower 3-parted), or t-clefl and merely oblique. Stamens 4, in- 

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

 nutlets. 1 1 orbs or shrubs, of various aspect : the foliage sometimes aromatic, as in 

 /,. cilritiilura, the sweet Verbena-shrub of the gardens, native of S. Alucin 

 w hich most of the spei ies belong.
