662 SOLANACEAE 



petiole, serrate, usually rather closely so, minutely pubescent or short-villous, the larger 2.5-5 

 cm. long, the upper leaves not much smaller than the lower ; flower-whorls all axillary ; calyx 

 pubescent, about 3 mm. long, teeth triangular-subulate, about equaling the tube; corolla pink 

 to violet or white, about twice as long as the calyx, nearly or quite glabrous. 



Moist rich soils, Boreal and Transition Zones; widespread in Eurasia and in eastern North America from 

 Newfoundland to Kentucky and Nebraska. In the Pacific States the typical species is rarely collected and 

 it is doubtful that it is native. Certainly most of the native plants belong to one or the other of the following 

 varieties. 



Mentha arvensis var. canadensis (L.) Kuntze, Rev. Gen. PI. 2: 524. 1891. (.Mentha canadensis L. 

 Sp. PI. 577. 1753.) Leaves lanceolate to oblong-lanceolate, cuneate-narrowed at base, pubescent; stems re- 

 trorsely pubescent. Widespread over North America from British Columbia to New Brunswick and southward. 

 In the Pacific States it ranges from Washington to northern Lower California. Type locality: Canada. 



Mentha arvensis var. lanata Piper, Bull. Torrey Club 29:223. 1902. Similar to variety canadensis, but 

 the stems and the under side of the leaves densely tomentose or woolly lanate, especially toward the top of the 

 stem. This is the most frequent form in the lowlands, especially near the coast, and ranges from, British 

 Columbia to southern California. Type locality: Parrott, Lincoln County, Washington. 



Mentha arvensis var. glabrata (Benth.) Fernald, Rhodora 10: 86. 1908. (Mentha canadensis var. 

 glabrata Benth. Lab. Gen. & Sp. 181. 1833.) Stems commonly rather strict and simple or few-branched, 

 glabrous throughout except for a minute retrorse puberulence on the angles of the stems; leaves oblong to 

 ovate. Restricted mainly to the higher altitudes (Boreal Zones) of the mountains ranging from British Columbia 

 to southern California. Type locality: not given. 



27. HtPTISJacq. Collect. 1 : 101. 1786. 



Annual or perennial herbs or shrubs, with opposite commonly toothed leaves, and 

 bilabiate flowers in usually dense axillary clusters. Calyx straight or oblique ; tube ovoid, 

 campanulate or cylindric; lobes 5, nearly equal, acute or awn-tipped. Corolla 2-lipped, 

 upper lip erect or spreading, the lower saccate, drooping. Stamens 4, declined and resting 

 on the lower lip, all anther-bearing; anthers confluently 2-celled. Nutlets smooth or 

 slightly roughened. [Name Greek, meaning resupinate or turned back, in reference to 

 the lower lip of the corolla.] 



A New World genus of about 350 species, ranging from the deserts of southern California to Texas and 

 southern Florida, southward to South America where it is most abundant. Type species, Hyptis verticillata 

 Jacq. 



1. Hyptis Etnoryi Torr. Desert Lavender. Fig. 4463. 



Hyptis Emoryi Torr. in Ives Rep. 20. 1860. 

 Mesosphaerum Emoryi Kuntze, Rev. Gen. PI. 2: 526. 1891. 



Erect aromatic shrubs, 1-3 m. high, with numerous slender usually straight branches, white 

 scurfy-tomentose throughout. Leaves ovate, 15-25 mm. long on petioles half as long, truncate at 

 base, crenulate ; flowers in axillary short-peduncled cymes, somewhat paniculately arranged at 

 the ends of the branches ; pedicels 1-4 mm. long ; calyx densely stellate-tomentose, 4-6 mm. long, 

 the teeth setaceous ; corolla violet, 4-6 mm. long ; filaments of upper pair of stamens pubescent, 

 the lower glabrous or nearly so. 



Gravelly washes and benches. Lower Sonoran Zone; eastern Mojave Desert and western Colorado Desert, 

 southern California, east to Arizona and south to Sonora and Lower California. Type locality: the lower Gila 

 River, Arizona. Jan.-May. 



Family 135. SOLANACEAE.* 

 Potato Family. 



Herbs or shrubs with alternate leaves (the upper leaves opposite in Petunia). 

 Flowers perfect, regular, solitary, umbellate, cymose or paniculate, axillary or ter- 

 minal. Calyx 5-toothed or 5-cleft (rarely 4-toothed), rotate, campanulate, or tubu- 

 lar, usually persistent. Corolla tubular, campanulate, infundibuliform or rotate, 

 5-lobed, the lobes valvate or intricate and usually plicate in bud. Stamens 5, in- 

 serted on the tube, alternate with the lobes. Ovary superior, 2-celled, several- to 

 many-ovuled ; style one ; stigma capitate, entire or slightly bilobed. Fruit a berry 

 or capsule. Seeds several to many, ovoid or compressed. Embryo straight or 

 strongly curved, subperipheral. Endosperm present. 



A family of about 90 genera and over 3,000 species, generally distributed but predominantly in the western 

 hemisphere. 



Seeds moderately to strongly compressed, mostly 1 mm. or more in diameter; embryo strongly curved. 



Shrubs with spiny branches; berry reddish and fleshy or greenish and dry and bony. 



1. Lyciutn. 



Herbs (except in some species of Solanunt) ; fruit a yellow, greenish or black juicy berry or a capsule. 



Corolla less than 4 cm. long or broad, usually much smaller; fruit 2-cened, not prickly. 



Fruit a capsule; corolla tubular or infundibuliform. 



Corolla 5-6 mm. long; capsule splitting apically; calyx-teeth not pungent. 2. Oryctes.
