716 SOLANACEAE (NIGHTSHADE FAMILY^ 



calyx-lobes lanceolate, in anthesis about equaling the tube ; fruiting calyx 2.5 

 cm. long, deeply umbonate at base ; corolla pale yellow^ 1.8-2.3 cm. in diameter. 

 (P. lanceolata Man. ed. 6, in part, not Michx.) — Dry hills, gravelly soil, etc., 

 Ct. to la., and southw. The typical form with villous spreading pubescence 

 seems relatively infrequent. The more common form has the pubescence on 

 stem and branches very short, the hairs retrorse or recurved, not viscid. Occa- 

 sional specimens are merely glandular-pulverulent. Var. intermedia Rydb. 

 Leaves larger, thinner, more entire; pubescence somewhat glandular when 

 young. — Ind. (according to Britton), and southw. 



15^ P. lanceolata Michx. More or less hirsute-pubescent with short stiS 

 hairs, varying to nearly glabrous; stems from rather sUmt subterranean shoots, 

 angled, somewhat rigid ; leaves oblong-ovate to lanceolate^ sparingly angulate- 

 toothed or more often entire ; corolla ochroleucous, with a more or less dark eye ; 

 calyx commonly hirsute, in fruit pyramidal-ovoid, 2.5-3.6 cm. long; berry 

 reddish. — Dry prairies and on sandy or clayey bluffs, 111. to Wyo. and N. Mex. ; 

 also southeastw. to S. C. 



4. NICANDRA Adans. Apple of Peru 



Calyx 5-parted, 5-angled, the divisions rather arrow-shaped, enlarged and 

 bladder-like in fruit, inclosing the 3-5-celled globular dry berry. Corolla with 

 border nearly entire. Otherwise much like Physalis. — Coarse smooth annual, 

 with ovate sinuate-toothed or angled leaves, and solitary pale blue flowers on 

 axillary and terminal peduncles. (Named for the poet Nicander of Colophon.) 

 Physalodks Boehnier. 



1. N. Physal6des (L.) Pers. {Physalodes^vMion.') — Waste grounds, near 

 dwellings and old gardens. July-Sept. (Introd. from Peru.) 



5, LYCIUM L. Matrimony Vine 



Calyx 3-5-toothed or -cleft, not enlarging, persistent at the base of the berry 

 Corolla funnel-form or salver-shaped, 5-lobed, the lobes imbricated and not 

 plaited in the bud. Stamens 5; anthers opening lengthwise. Style slender; 

 stigma capitate. Berry small, 2-celled. — Shrubby often spiny plants, with 

 alternate and entire small leaves, and mostly axillary small flowers. (Named 

 from the country, Lycia.) 



1. L. HALiMiFOLiuM Mill. (CoMMON M.) Slirub with long sarmentose 

 recurved-drooping branches, smooth, sparingly if at all spiny ; leaves oblong- 

 or spatulate-lanceolate, often fascicled, narrowed into a short petiole ; flowers 

 on slender peduncles fascicled in the axils ; corolla short funnel-form, greenish- 

 purple ; style and slender filaments equaling the corolla-lobes ; beny ovoid, 

 orange-red. (X. vulgare Dunal.) — About dwellings, and sometimes escaped 

 into waste grounds. (Introd. from Eu.) 



6. HYOSCYAMUS [Tourn.] L. Henbane 



Calyx bell-shaped or urn-shaped, 5-lobed. Corolla funnel-form, oblique, with 

 d, 5-lobed more or less unequal plaited border. Stamens declined. Capsule 

 inclosed in the persistent calyx, 2-celled, opening transversely all round near 

 the apex, which falls off like a lid. — Clammy-pubescent fetid narcotic herbs, 

 with lurid flowers in the axils of angled or toothed leaves. (Name composed 

 of us, a hog, and /cua/xos, a bean; said to be poisonous to swine.) 



1. H. NIGER L. (Black H.) Biennial or annual ; leaves clasping, sinuate- 

 toothed and angled ; flowers sessile, in one-sided leafy spikes ; corolla dull 

 yellowish, strongly reticulated with purple veins. — Open sandy soil and waste 

 places, e. Que. to Out. and Mich. ; also rarely about ports southw. June. July
