N ROBOT. 
by Ware in 1821, Stem 2 or 3 inches high, 
leaves half inch long, head large, flowers green- 
ish. I have a var of P. lutea near this same 
size and habit, but with few leaves narrower, 
heads depressed, flowers realy bright yellow 7 , 
wings broader obovate acuminate : it will be 
my var pauci folia, and they all evince a ten- 
dency to deviate from P. lutea. 
GENTIANIDES. 
This lovely family of plants was in otter con- 
fusion, as I have proved in rectifying it, in 0. 
tellur. 435 to 500, where many N. G. and sp. 
are established. I have also restored the G. 
Anthop^gon, Pneumonanthe, Dasistepha, Ci- 
minaliSjCicendia, Tretorhiza Slc of former bo- 
tanists, neglected by the linnean blenders. I 
there gave also some new N. Amer. sp. and I 
still mean to give hereafter their complete mo- 
nograph, our species have been increased late- 
ly by myself and Hooker to 50 or 60, while 
Linneus had only half a dozen of this continent, 
I now must merely add some other interesting 
novelties.

this fine G. discovered by Muhlenberg since 1790,

omitted or mistaken for a variety by our botan- 
ists (myself included) but now restored and fix-

branches, leaves uncial, narrower than in A .
