(308 VERBENACEJB. Verbena. 



1. VERBENA, Linn. Veevaix. 



Calyx tubular or plicately prismatic, 5-toothed, one tooth often shorter. Corolla 



salverform ; the tube sometimes curved ; the limb more or less unequally 5-cleft. 



Stamens 4, included ; the upper pair sometimes sterile. Stigma of two dissimilar 



lobes, one of them smaller and mostly abortive. Ovary 4-celled, in fruit splitting 



into 4 one-seeded little nutlets. — Herbs (or a few South American species shrubby); 



with the flowers in single or panicled spikes or heads, small, or in some showy. 



The commoner species are apt to hybridize naturally, and the hybrids are not rarely 



fertile. 



Chiefly an American genus, mainly South American ; the few Californian representatives weeds 

 or weedy, and only two or three truly indigenous. 



§ 1. Flowers small in proportion to the spike : anthers glandless. 



* Stem erect : spikes filiform and with the flowers or fruits at length more or less 

 scattering : bracts usually shorter than the fruiting calyx. 



+- Annual, or the base becoming ligneous and of longer duration : stems a span to 2 

 feet high, slender : some of the leaves pinnatifid, tapering at base, the loiver into a 

 ■margined petiole. 



1 . V. canescens, HBK. Hoary-hirsute : leaves oblong-lanceolate and cuneate- 

 obovate, rigid, sharply incised or pinnatifid : spikes mostly solitary, terminating the 

 branches ; some of the bracts exceeding the flowers : corolla bluish, the limb a line 

 or so in diameter. — Nov. Gen. & Sp. ii. 274, t. 136. V. remota, Benth. PI. Hartw., 

 from Mexico, is a simple-stemmed form. 



Cafion Tantillas, south of San Diego Co., Palmer. Probably extends within the State, as it 

 does eastward to Texas and Mexico. 



2. V. officinalis, Linn. Minutely roughish-pubescent, loosely branched : leaves 

 obovate or oblong, or the upper lanceolate, some merely incised, others once or twice 

 pinnatifid or 3 — 5-cleft : bracts all shorter than the calyx : corolla purplish or lilac, 

 the limb 2 lines in diameter, sometimes more. 



Dry waste grounds through the western part of the State, probably naturalized, but the species 

 occurs round the world. A stouter form, and with limb of corolla 3 or more lines in diameter, 

 answering to V. sororia, Don, was sent from San Diego by Dr. Hitchcock. 



+- +- Perennial, 2 to 5 feet high : leaves serrate or merely incised. 



3. V. polystachya, HBK. Scabrous with very short partly hispid pubescence, 

 green, paniculately branched : leaves from oblong to lanceolate (mostly about 2 

 inches long), sessile by a narrowed base, or the lower short-petioled, coarsely serrate 

 or sparingly incised : spikes loosely panicled or sometimes solitary : corolla purplish 

 or nearly white, the limb about a line in diameter. — V. polystachya, V. biserrala, & 

 (according to Schauer) V. veroniccefolia, HBK. 1. c. V. Carolinensis, &c, Dill. Hort. 

 Elth. 407, t. 301. V. Carolina, Linn., but it is a Mexican, not a Carolinian spe- 

 cies. V. Caroliniana, Spreng. ; Hook. & Arn. Bot. Beechey, 156; Schauer in DC. 

 Prodr. xi. 546. 



Monterey or San Francisco, according to Hooker & Arnott in the Botany of Beechey's Voyage. 

 Los Angeles, Wallace ? 



V. UETICIFOLIA, Linn. Green, minutely roughish-pubescent : leaves ovate and ovate-lanceo- 

 late, mostly acute or acuminate, simply or doubly serrate, all but the uppermost with rounded 

 base and a slender petiole, the larger 4 or 5 inches long : panicled spikes very slender : corolla 

 mostly white. 



A common weed in the Atlantic States, extending into Mexico, &c. ; very likely to reach Cali- 

 fornia : the specimen sent by Wallace, mentioned under the preceding, is too incomplete to deter- 

 mine whether it belongs to that or the present species.
