cluded the Genriana quinguefolia of the various works of 
Linnaus, and the Gentiana quingueflora of WiLLDENow, 
Lamarck, and SprenceL; because reference is by them 
made to Flora Danica, and because the leaves are generally 
described as ovate or oblong, and the stem simple. I have . 
abstained from quoting Grentiana amarelloides of Micuaux, 
because he describes his plant as smaller than G. ama- 
rella, with oval leaves; small, lateral as well as terminal 
flowers, of pale yellow colour ; and having the segments of 
the limb lanceolate. In all these respects does our plant 
differ. I have quoted with doubt Exuiorr, Torrey, and 
Breck, on account of references they make, and because 
some parts of their descriptions neither accord with native 
nor cultivated specimens ; yet I think they must allude to 
the plant now described. In the other writers quoted, the 
references are, I think, sometimes mistaken, but the cha- 
racters are corrected. 
Descr. Root annual, dichotomously branched. Stem 
(nine to twenty inches high) single, erect, square, winged, 
branched ; branches decussating, spreading. Leaves stem- 
clasping, deltoideo-cordate, glabrous on both sides, palest 
below, three to five-nerved and obscurely reticulate, entire 
in the margin, slightly crisped, nerves prominent below. 
Flowers clustered at the extremity of the stem and branches, 
generally from three to five together, pedicellate, or if 
single in the axils of the leaves, it is only from the degene- 
ration of the branches ; pedicels erect. Calyx small, green, 
quinquefid, segments lanceolate, slightly spreading. Corolla 
(before expansion of the limb ten lines long, three lines in 
its greatest diameter in cultivated specimens, in native spe- 
cimens often smaller) pale lilac: tube (seven lines and a 
half long) clavate ; limb five-parted, segments ovate, aris- 
tate ; throat naked. Stamens as long as the tube ; filaments 
adhering to the corolla as far as their middle, to which point 
they enlarge, and then gradually contract upwards, chan- 
nelled on their inner surface, unconnected with each other : 
anthers small, leaden coloured, bursting on their outer sur- 
face; pollen pale, its granules nearly spherical. Pistil as 
long as the stamens : Stigmas small, acute : Germen linear- 
lanceolate, greenish-leaden-coloured. Graham.

Botanists, from whom I have received many specimens, and
