S. nocturna, L., although credited to this country by Torr. & Gray 
and by various subsequent authors, is not represented from America in 
the leading herbaria of the country. Most if not all of the specimens 
referred here are either S. Gallica or S. noctiflora. 
+ + Inflorescence dichotomously racemose. 
S. picnoroma, Ehrh. Tall, more or less hirsute and viscid: root 
annual or biennial: leaves lanceolate or oblanceolate: flowers short 
pedicelled or subsessile, larger than in the preceding, } inch in 
diameter: petals white or roseate, the blade obovate, more or less 
deeply bifid: calyx cylindric in anthesis, becoming ovate in fruit, the 
prominent green nerves strictly simple, hirsute. — Beitr. vii. 143. 
Reichb. 1. c. vi. t. 280.— A European species somewhat intermediate 
between S. Gallica and S. noctiflora ; ballast and waste land, Phil- 
adelphia, Martindale ; Trenton, Volk; Texas, Nealley. The form 
RACEMOSA, Rohrb., S. racemosa, Otth in DC. Prodr. i. 384, with more 
pubescent leaves tending to be clustered about the base has been found 
by Prof. Greene sparingly introduced in fields about Berkeley, Cal. 
Fl. Francis. i. 116. 
+ + + Inflorescence cymose or paniculate, not distinctly racemose: 
++ Calyx equally and conspicuously 20-25-nerved. 
S. multinervia, Wars. Erect, a foot high, pubescent throughout 
and somewhat viscid-glandular above : leaves narrowly oblong oF lin- 
ear, acute: inflorescence cymose with unequal branches: calyx ovate 
in fruit, contracted above, 5 lines long: petals small, purplish, un@P" 
pendaged, not exceeding the subulate spreading calyx teeth: capsule 
narrowly ovate. — Proc. Am. Acad. xxv. 126; Zoe, i. 254.— South- 
botanists are inclined to regard it as an introduced plant, and er 
son, in Erythea, i. 58, erroneously reduces it to S. conoidea, of the 
attenuate calyx teeth, and long-necked flask-shaped capsules. 
++ ++ Calyx 10-nerved. 
= Viscid-pubescent or hirsute. : 
S. noctirtora, L. A coarse species a foot or two in height with 
lanceolate or ovate-lanceolate leaves 2-3 inches long: flowers usually 
few in loose cymes, fragrant: calyx large, in fruit ovoid, white with 
green nerves tending to anastomose: the teeth attenuate : petals bifid “
