It appears to be as follows. In 1790 Necker published a ee 
system of plants in which the Mosses and Jungermanniacee consti- 
tuted one pants — Fhe ‘yganophytum, and certain unspecified Hypna 
of Linneus formed a natural species—Pancovia see . Bot. iii. 
p. 328, n. 1739). - However, Necker’s natural or mologie system 
failed to gain acoeptance, But in 1867 Kickx (Flor Crypt. des

review of Dr. Britton’s Illustrated Flora of North America con-

on ‘‘the so-called eames Club Check List” in the Botanical 
Gazette for June last—a paper which, as he truly says, ‘‘ shows 
very conclusively that the icon aa on which the pends is based are 
inconsistent’; and he regrets that ‘‘such names as will be o 
short-lived and idee add Pecafuzion to the tangle of synonymy ”’ 
have been Mr. Fernald himself contributes examples showing 
that the “ Roshestar code” has not been followed in the Illustrated 
Flora, which, however, “in spite of _ inaccuracies and incon-
