them to rank as a distinct order. The Parnassise, which in many 

 respects approach the Hypericacese, but the flowers of which are, 

 as indicated in former editions of the Manual, sometimes clearly 

 perigynous, and the Grossulariae are removed by the author to 

 Saxifragaceae. The Halorageae, formerly regarded as a sub-order 

 of Onagraceae, he now considers to have characters sufficient to 

 constitute an ordt%\ Under Liliacese, as here extended and re- 

 arranged, are included the Trillidese, Melanthiese, and Uvularieae. 



Among the genera there are not many changes to note. 

 Atragine, distinguished by the presence of petals which gradually 

 merge into stamens, is included in Clematis. Iodanthus and 

 Turritis are referred to Arabis, and Alsine, Mcehringia, and 

 Honkenya, also considered by some authors, as well as in former 

 editions, as genera, and of which the last named has considerable 

 claims to generic distinction, are comprised in Arenaria, Further, 

 among endogens, the older genus Habenaria, distinguished from 

 Orchis by its naked and exposed separate glands or viscid disks, 

 is revived in this edition, and the Gymnadenia and Platanthera of 

 former editions referred to it. Whilst on the subject of genera, 

 it may be added that it admits of grave doubt whether an author 

 when changing a species from one genus to another should wholly 

 suppress the name of the original describer. 



Mr. Paine's new Water Lily, Nyrnphcea tuberosa, from Oneida 

 Lake and other parts of the Union, and which has been recently 

 observed near Belleville by Mr. Macoun, is fully described. 

 Arabis petrcea Lam., which occurs on the Canadian side of Lake 

 Superior, appears now as a Uuited States plant, having been 

 found on Willoughby Mountain by Mr. Horace Mann. Oxytro- 

 pls campestris DC, it will interest Quebec and New Brunswick 

 botanists, is to be looked for about the Maine boundary line. 

 The other species, 0. Lamberii Pursh, an interesting local plant 

 of the Province of Quebec, is another noticeable addition to Dr. 

 Gray's work. Such are also Parnassia parviflora DC, one of 

 our Anticosti plants, which has been observed on the north-west 

 shore of Lake Michigan, and Sedum Rhodiola DC, a rather 

 boreal plant of Anticosti, Labrador, and Newfoundland, which has 

 been met with in Maine and, curiously enough, in Pennsylvania 

 on cliffs of the Delaware Biver above Easton. Among other 

 recent additions of interest to the flora of tne Northern United 

 States there may be mentioned, as species previously known to 

 occur in either Quebec or Ontario, Matricaria inodora Linn, a
