44 VALERIA NACE^. Valeriana. 



corolla almost filiform, half-inch and more long, several times longer than the throat and 

 Ijmb. — n. i. 18; Nutt. Gen. i. 20; Torr. & Gray, 1. c. — Alluvial river-banks, Pennsylvania 

 to Illinois, Missouri, and Tennessee ; first coll. by Michaux. 



* * * Sarmentose-climbing or diffuse, with fibrous roots, glabrous: flowers very numerous in 

 diffuse and compound paniculate cymes: bracts very small: corolla minute, seldom over a line 

 long. 



V. SOrbifolia, IIBK. A diffuse form of the Mexican species: stem weak, 2 or 3 feet long, 

 springing from an annually produced small oblong tuber: leaves pinnate (except sometimes 

 the radical), 5-l."}-foliolate; Icafiets from rounded-ovate to oblong-lanceolate, coarsely ser- 

 rate, or even laciniate : cymes loosely flowered in an elongated and naked (often foot long) 

 terminal panicle. — Nov. Gen. & Spec. iii. 332. — Canon in the Huachuca Mountains, S. Ari- 

 zona, Lemmon, in a form with only 5 to 7 unusually large and broad leaflets, some almost 

 2 inches long, from rounded-ovate to oblong. (Mex.) 



V. SCandens, L- Hoot unknown : stem sarmeutose and feebly twining, branching : leaves 

 long-petioled ; cauline 3-foliolate, with leaflets from deltoid- to oblong-ovate, acuminate, 

 entire or repaud, rarely with a few teeth, or lowest leaves simple and cordate: panicles 

 effuse, axillary and terminal, elongated, the ultimate branches with the sessile flowers spi- 

 cately disposed. — Spec. ed. 2, i. 47 ; Willd. Spec. i. 180 ; DC. 1. c. ; Torr. & Gra}-, Fl. ii, 47. 

 — Thickets in S. Florida, climbing several feet high. ( W. lud. to Brazil.) 



2. VALiERIANELiLA, Tourn. Cokn Salad. (Diminutive of Valeri- 

 ana.) — Annuals, commonly winter-annuals (of the northern temperate zone), 

 mostly low or slender and erect, ours glabrous or nearly so, except the fruit : 

 leaves similar in all the species, from obovate to oblong and spatulate, entire or 

 upper ones occasionally incised or toothed, radical rosulate, cauline sessile or even 

 somewhat connate at base : flowers variously glomerate-cymose, the corolla from 

 white to rose-color or rarely bluish. As in some species of Valeriana., so in some 

 of these, the hermaphrodite flowers in diiferent individuals are dimorphous as to 

 size of corolla and exsertion of stamens and style, yet not as in heterogone dimor- 

 phism. — VailL, llaller, &c. ; Gray, Proc. Am. Acad. xix. 81. Valerianella &

§ 1. Valerianella proper. Corolla with nearly regular 5-parted limb, fun- 

 nelform or more open throat with or without a small saccate gibbosity at its base 

 anteriorly, and a short proper tube : stamens 3 : fruit with the two empty cells 

 manifest, or often enlai'ged and closed, sometimes at length confluent into one 

 and rarely bursting : calyx-limb in American species none, or a mere tooth or 

 oblique border : stem dichotomous above ; the branches or pedunculiform branch- 

 lets terminated by corymbosely disposed glomerate cymes or cymules of small 

 flowers. — Vahria7iella.M(£.nc\x ; Dufresne, Hist. Valcr. 56 ; Krok, Monogr. Valer.

* Introduced species: corolla bluish : a gibbous corkv mass at the back of the fertile cell of the fruit. 

 V. olit6ria. Poll. Fruit flattish and obliqucl}^ roundish-rhomboidal : empty cells as large 

 as fertile one and its corky back, contiguous, the thin p.artitiou between them at length 

 breaking up. — Hist. PI. Palat. i. 30; Moench, 1. c; Dufresne, Valer. 56, t. 3, f. 8; Krok,
