tent, stigma biiamellate broad, capsule elliptic 
2valve unilocular, polysperme, seeds scrobicu- 
late inserted on 4 large placentas. Perennial , 
ramose , flowers axil, pedunculate — I now add 
another beautiful N, G. to the Gentianides : it 
is next to Swertia and Narketis , but with the 
calix and corolla of Sabatia &c. My Narke- 
tis fl. tel. 477 based on various sp. of pentan- 
drous Swertias included even several G. this, 
another my Synallodia japonica , with 2 sta- 
mens united, formed by Swertia rotata of Thun- 
berg ; and Gentiana pratensis with very une- 
qual calix and no appendages ? perhaps another 
Leimanisa R. the name of this applies to the 
large biiamellate stigma, it shows beautifully 
the opposition of stamens essential to the Gen- 
tianides. 
9 7. Bilamista grandiflora Raf. Gentiana 
do Coll. herb, ramose 2-3dichotome, branches 
fastigiate terete rugose, leaves ovatoblong acute 
trinerve ; peduncles axilary and terminal rigid 
angular, calix segments subulate, corolla thrice 
as long, segments obovate obtuse — fine robust 
plant of Red river Louisiana and Arkanzas,ses- 
quipedal, leaves biuncial, flowers white ? (ful- 
vous in dry specimen and leaves blackened) 
very large 2 or 3 inches wide, nearly marces- 
cent and persistent like the style ; capsule large 
very peculiar black rugose, seeds numerous 
minute dotted: the glandular appendages are 
minute somewhat crested and at sinusses in- 
stead of segments. 
I have not yet exhausted the N. G. and sp. 
of this family, there are still others blended in 
Swertia , Exacum , Chironia . . . and many un- 
noticed sp. of Sabatia , Pleienta , Xolemia . . *
