Revision of the American Species of Epilobium occurring North 
of Mexico. William Trelease. (2d Ann. Rep. Missouri Bot. 
Gard. 69-117; 48 plates. Reprint issued April 22d, 1891). 
Professor Trelease has made a critical study of the species of 
this difficult genus, extending over more than two years. He 
has found that the greatest confusion prevails in the local floras 
and herbaria of this country as to the species, and bases his work 
on Haussknecht’s “‘ Monographie der Gattung Zpzlobium,” pub- 
lished in 1884, although he has not been able to recognize in 
American material all the species maintained by that author and 
finds several undescribed ones to add. 
Copious references to literature on the biologic features of the 
genus are given in the introduction. 38 species are then described 
at length, the following as new: £. clavatum, from Washington 
to Wyoming and Utah; &. wrsinum, Parish, California to Wash- 
ington; £. delicatum, Oregon, besides several new varieties. 
Original names are upheld, and authors cited in parenthesis if the 
rank of a species has been changed to variety; there is one ap- 
_ parent exception, however, in E. oliganthum, Michx., (1803) being 
oF _ referred as a variety to Z. /ineare, Muhl (1813). The plates il-
