slender petioles: pedicels usually filiform and equaling the petiole: corolla 12 to 18 
mm. broad,—Thickets and banks of streams, extending from Arkansas into Texas 
where also occurs var. CINERASCENS Gray, which is greenish, with much shorter 
and less dense pubescence, roundish leaves rarely at all cordate (some of the lower 
with cuneate base), and sometimes shorter pedicels. 
— — Pubescence stellular, or simple and rigid, or nearly none: leaves from oval to lan- 
ceolate-lincar and tapering into the petiole. 
11. P. viscosa L. Cinereous or when young almost canescent with short stellate 
or 2 or 8-forked pubescence: stems ascending or spreading from slender creeping sub- 
terranean shoots: leaves ovate or oval, varying to oblong or obovate, entire or 
undulate: corolla greenish-yellow, with a more or less dark eye: fruiting calyx glo- 
bose-ovate: berry yellow or orange.—In sands on or near the Atlantic coast, and 
represented along the Texan coast by var. SPATHUL.EFOLIA Gray, with spatulate or 
oblong-lanceolate leaves gradually tapering into the petiole (P. pubescens Eng. & 
Gray, Pl. Lindh. P. lanceolata, var. spathulefolia Torr, Mex. Bound.). 
12. P. lanceolata Michx. More or less hirsute-pubescent with short stiff mostly 
simple hairs, varying to nearly glabrous: stems from rather stout subterranean 
shoots, angled, somewhat rigid: leaves oblong-ovate to narrowly lanceolate, sparingly 
auguiate-toothed to wndulate or entire: corolla ochroleucous, with a more or less 
dark eye: calyx commonly hirsute, in fruit pyramidal-ovate: berry reddish. (P. 
Pennsylvanica Gray, Man., in part, not L.)—Dry open ground and bottoms, through- 
out Texas. Associated with var. Lasvicgata Gray, which is glabrous or almost so 
throughout, or with some very short hairs on young parts. In wet woods, in east- 
ern Texas, represented by var. uirra Gray, with much of the hirsute-pubescence of 
the leaves 2 or 3-forked, as also are some of the abundant villous-hispid hairs of the 
stem. 
6. MARGARANTHUS Schlecht. 
Resembles an annual Physalis on a small seale, except in the globu- 
lar (livid or violet-tinged) corolla: the small berry wholly ineluded in 
the globular and vesicular fruiting calyx, rather dry, 20 to 30-seeded. 
1. M. solanaceus Schlecht. Nearly glabrous, crect, divergently branched: 
leaves membranaceous, ovate and ovate-lanceolate, entire or somewhat repand, 
oceasionally 1 or 2-toothed, 2.5 to 5 cm. long, slender-petioled: pedicels short, re- 
curving: corolla barely 4mm, long, and globular-conical fruiting calyx 8 to 12 mm. 
long.—Southern and western borders of Texas. 
7, LYCIUM L. (MATRIMONY-VINE.) 
Shrubby mostly spiny plants, with alternate and entire small leaves, 
mostly axillary small flowers, 3 to 5-toothed or cleft calyx not enlarg- 
ing and persistent at base of berry, funnelform or salverform 5-lobed 
corolla, 5 stamens with anthers opening lengthwise, slender style with 
capitate stigma, and small 2-celled red or reddish berries. 
1. L. pallidum Miers. Glabrous: leaves pale, spatulate and oblanceolate, 2.5 to 
5em. long: pedicels about equaling the deeply 5-cleft calyx: corolla funnelform, 
nearly 25 mm. long, greenish tinged with purple, with broad and rounded lobes: 
filaments exserted.—Southwestern border of Texas. 
2. L. puberulum Gray. Leaves obovate and oblong-spatulate, 6 to 12 mm. long, 
minutely and densely puberulent: flowers solitary and sessile in the fascicles of 
leaves: corolla tubular-funnelform, 8 to 10 mm. long, white, with the triangular-
