ymy — in the Compositae there are more synonyms than accepted 

 species — there are many interpretations with which other stu- 

 dents will not agree. I suspect, for example, that Carduus pul- 

 cherrimus Rydb. is not a close ally of C. Hookerianus erioceph- 

 alus (Gray) A. Nelson, to which it is referred; that Arnica 

 gracilis of the new Manual may not he. Arnica gracilis Rydb., 

 and that Artemisia coloradensis is much nearer to A. ludovia 

 ana than to A. Wrightii^ of which it is made a variety. 



When a book like this appears, we first look to pee if the 

 rare species which we have stumbled upon are included, and 

 whether some of the newly described species have passed mus- 

 ter and taken their place in the ranks of the veterans — or, per- 

 haps, as Professor Nelson would say, whether they have been 

 taken from the ranks of probationers, and admitted to lull mem- 

 bership. 



While these observations may be considered as kindly crit- 

 icisms, there are many excellent features in the book — the good 

 descriptions, the keys to the genera and species, the date and 

 place of publication — representing no light labor, which no one 

 will overlook. 



Professor Nelson is the honored teacher of biology in the 

 University of Wyoming, one of the men who has grown with 

 the opportunities of the west, and who has made time to do 

 more than his work of teaching.

THE NORTH AMERICAN LUPINES— I 

 By A. A. Hkli.kr 



As a preface to this series of papers, it ma\ be well to state 

 that thev are offered preparatory to an illustrated monograph of 

 North American species of the genus. This is a task that ma\ 

 not be undertaken lightly. Thus far we have had two revisions 

 ofthe genus, both bv men who knew little of the plants in the 

 field. Of the two, Agardh's "Synopsis Generis Lupini," pub* 

 lished in r835, still remains the one to which we must look foi
