This, the “ Closed gentian” of the Americans, is one of the . 
handsomest species of the genus; it was long confounded 
with an American close ally, the G. Saponaria of Linneus, 
from which it was first distinguished by Grisebach, who, 
however, does not observe,that the G Saponaria (erroneously 
quoted as G. Catesbei, is De Candolles Prodronus 1. c.), figured 
in this work (t. 1039) is, as far as can be ascertained from the 
imperfect description and very indifferent drawing, referable 
to G. Andrewsii. The chief diagnostic characters between 
these two species are the linear or spathulate calyx lobes of 
G. Saponaria, which equal or exceed the tube, its light blue 
corolla, with distinct lobes, and cleft appendages, and its acute 
narrowly winged seeds. - Of these characters the colour of the 
corolla, and the form and size of the calyx lobes are the only 
ones determinable from the figure at t. 1039, and as these 
accord with those of G. Andrewsii, I have little doubt of the 
plate in question representing a miserable specimen of this 
plant.
