There has been little effected in taking up old generic names, but 
we note that Mr. Hitchcock adopts Castalia for Nymphea and 
Homalocenchrus for Leersia. The catalogue is a most important 
contribution to geographical botany, and should stimulate bot- 
anists all over the country to produce others of equal merit.

Catalogue of Canadian Plants.—Part V. Acrogens. John 
Macoun. (8vo, pp. 249-428, Montreal, 1890). 
This part completes the second volume of Prof. Macoun’s 
great Catalogue, containing the Pteridophyta (the Filices and 
Ophioglossacee contributed by Dr. Burgess), included in Nos. 
2956-3054. The greater part of the present fascicle is taken up 
with additions and notes on Parts I-IV. a very considerable 
number of Flowering Plants being added. Of these Avadis Col- 
umbiana, Macoun, and Ruppia lacustris, Macoun, are described 
as new ; the latter is however antedated by Dr. Watson’s name 
R. occidentalis, applied to the same plant. Mr. Macoun de- 
scribes also two new varieties of Carex canescens. Prof. Scrib- 
ner has studied the Graminez, new varieties and species being 
indicated in the genera Alopecurus, Stipa, Agrostis and Festuca. 
Mr. Arthur Bennett has examined the Potamogetons, and several 
novelties are listed. Part VI. of the Catalogue, including Char- 
acez, Musci and Hepatice is announced for the present year. 
We congratulate Prof. Macoun on the very successful progress 
his work. He is contributing more at the present time to our 
knowledge of North American Botany than any one else, and
