 3 to 5, involucre of 4 leaves.

 italica Raf. Chlora imperfol. L. fol. sess. ova- 

 is oppositis. Very distinct Genus. Thus all 

 theChloras were of different Genera! I chang- 

 ed the name because too similar to CJdoris 

 and Chloranthus. 



After such an evidence of indispensable re- 

 form in 3 Genera of old in this Centuria alone, 

 it will appear that those Genera Polygonum, 

 Gentiana and Chironia were without any real 

 peculiar characters, the species merely held to- 

 gether by no one knows what, except a kind 

 of fascies or appearance. The Gentians now 

 very numerous, amounting perhaps to 150 spe- 

 cies, may be all reduced to the reformed genera, 

 by a little care, and I may even do it hereafter. 

 But there are several anomalous species types 

 of subgenera. The G. pratensis probably a 

 Narketis has a very unequal calix. The G. au- 

 riculata has also a similar calix with 2 sepals 

 cordate ; it has 4 or 5 parts to the campanulate 

 corolla, and 4 or 5 stamens. Is it a Genus? 

 Dicardlotis Raf near Pogohlephis.
