Gentiana. 



GENTIANACEiE. 



107 



Valleys of the Adirondack mountains, Essex county. Fl. Early in August. I have fol- 

 lowed Hooker and Grisebach in referring this plant to G. Saponaria of Linnasus, though I 

 still think it scarcely distinct from G. Pneumonanthe. I have never met with the broad-leaved 

 forms described by these learned botanists. 



2. Gentiana Andrewsii, Griseb. Andrews's Gentian. 



Stem ascending ; leaves ovate-lanceolate, acuminate, rough on the margin ; flowers ag- 

 gregated, nearly sessile, bracteate ; lobes of the calyx shorter than the tube, ciliolate-rough ; 

 corolla clavate, with the orifice connivent, the plicae somewhat 2-lobed and cut, larger than the 

 nearly obliterated lobes of the corolla ; anthers connate ; seeds broadly winged. Griseb. I. c. 

 G. Saponaria, Frail. Gent. p. 32, ex Griseb. Gent. p. 287 ; Bart. fl. N. Am. t. 79 ; Torr. 

 fl. I. p. 286 ; Bigel. fl. Bost. p. 105 ; Beck, bol. p. 239 ; Darlingt. fl. Cest. p. 165. 



Root biennial? Stem 12-18 inches high, erect, simple, smooth. Leaves about three 

 inches long and an inch or more in breadth, 3-nerved, very smooth except on the margin, 

 which is a little rough. Flowers crowded in a terminal fascicle or head, with one or two in 

 axils of the upper pairs of leaves. Segments of the calyx ovate-lanceolate, about half the 

 length of the tube, minutely ciliate. Corolla about an inch and a half long, tubular-ventricose, 

 nearly closed at the orifice, bright blue, sometimes pale ; the primary lobes very short or 

 almost wanting, and the secondary ones or inner folds broad, semiovate. Anthers sagittate. 

 Stigmas oblong-lanceolate, at length diverging or recurved. Capsule stipitate. Seeds oblong, 

 with a distinct broad thick opake wing, which is obtuse at one end and rather acute at the 

 other. 



Loiv grounds and moist woods ; frequent. September - October. The expanded corolla, 

 represented in our plate 80, fig. 3, was incorrectly drawn with the primary lobes laciniate. 

 They are sometimes, particularly in withered flowers, slightly 1- or 2-toothed. The secondary 

 lobes or plicae can easily be distinguished by their being opposite the stamens, whereas the 

 primary ones alternate with them. 



3. Gentiana ochroleuca, Frail. Ochroleucous Gentian. 



Stem ascending; leaves ovate -lanceolate and obovate, rough on the margin; flowers 

 aggregated, sessile, bracteate ; lobes of the calyx unequal, as long as the tube ; corolla 

 (ochroleucous) with the lobes acute ; intermediate plicas entire, acute, very short ; anthers 

 distinct ; seeds not winged. Griseb. in HooJt.fl. Bor.-Am. 2. p. 56, and Gent. p. 288 ; Frail. 

 Gent p. 35 ; Bot. mag. t. 1531 ; Pursh, fl. 1. p. 185 ; Ell. sk. I. p. 340 ; Torr.fl. 1. p. 286 ; 

 Beck, bot. p. 239 ; Darlingt. fl. Cest. p. 165. G. Saponaria, Miclix. fl. 1. p. 176 (ex Griseb.). 



Leaves most frequently obovate, but often broadest at the base, or cordate -lanceolate. 

 Corolla variable (Griseb). 



On Long Island (Dr. Eddy) ; Yates county (Dr. Sartwell). I have no specimens of this 

 species from within our limits, and suspect that what has been taken for it is one of the forms 

 of G. Andrewsii.
