 hispid with retrorse bristles, especially on the angles of the stem : leaves 

 310 in. long, oblong-ovate, subcordate, crenate-serrate, villous or 

 hirsute above, villous-tomentose beneath, rather long-petioled : calyx 

 tubular-campanulate, its teeth cuspidate: corolla rose-red, 1 in. long, the

OEDEB LXXIX. VERBENACE/E. 



Square-stemmed opposite-leaved plants analogous to Labiatx; but 

 the inflorescence not verticillastrate; 5-toothed calyx not always per- 

 sistent; the corolla less irregular. Ovary not deeply lobed; when mature 

 splitting into 2 or 4 nutlets with lateral insertion, or covered with a 

 pulp, and thus drupaceous. 



1. VEBBEXA., Pliny. Herbs, with flowers in panicled spikes at 

 summit of leafy stem or branches. Calyx prismatic, 5-angled and 

 -toothed, at least in some species deciduous at the maturing of the fruit. 

 Corolla salverform; limb unequally 5-lobed. Stamens 4, on the tube of 

 the corolla, not exserted. Stigma of 2 dissimilar lobes. Ovary when 

 mature splitting into 4 elongated laterally inserted nutlets. 



1. V. hastata, L. Perennial, erect, 3 6 ft. high, minutely pubescent: 

 leaves oblong-lanceolate, acuminate, coarsely and incisely serrate, some of 

 the lower haslately 3-lobed: spikes many, dense, 2 4 in. long, in a close 

 terminal panicle: corolla 2 lines long, deep blue; limb 2 lines wide. 

 Common on the banks of the lower Sacramento. Sept. 



2. V. prostrata, B. Br. Stems rigidly erect and 2 ft. high, or more 

 slender and ascending or decumbent, seldom or never prostrate: herbage 

 more or less hirsute-pubescent: leaves extremely variable, obovate, spatulate- 

 obovate, oblong or cuneate-oblong, tapering into a marginal petiole, 

 sharply serrate, deeply incised, or pinnately 3 5-cleft: spikes long, 

 slender, solitary or several, or not rarely many, short and dense, 

 arranged in a terminal panicle: bracts subulate, not exceeding the 

 calyx: corolla rather light blue, 2 lines long and broad. Bather common 

 in moist places along the Bay, and by streamlets among the hills. 



3. V. bracteosa, Michx. Perennial, stoutish, rather rough-hirsute, 

 much branched from the base and nearly prostrate: leaves cuneate- 

 oblong or obovate, pinnately incised or cleft, or coarsely toothed; the 

 lower narrowed into a short margined petiole, the uppermost passing 

 into the bracts of the long dense spikes which are sguarrose with the rigid 

 lanceolate sparsely hispid foliaeeous bracts that subtend the flowers: 

 corolla very small and slender, blue. Lower San Joaquin and south- 

 ward.
