BOOK REVIEW 
Flora of Mount Baker 
Local floras are available for altogether too few regions in 
America. It is, therefore, with considerable interest that the ap- 
pearance of one more has been noted under the attractive title of 
“Flora of Mount Baker.”! The authors are to be commended 
upon their high aim, “to provide a ready source from which to 
learn the names and nature of the plants” of this interesting re- 
gion in the extreme northwestern United States. 
The publication contains keys to the families, genera and 
species, and brief descriptions of 334 species and varieties. 
Twenty-one species are illustrated with line drawings. Eleven 
plants, mostly varieties and forms, are described as new. 
It is to be regretted that the authors did not make this flora 
more nearly complete by amplifying their list of species by in- 
cluding more of the records of earlier collectors of the region or 
or by more intensive field work, especially in the “lower for- 
ests,” included in the area covered. To one who has made nu- 
merous collecting trips on Mount Baker and its surrounding 
ranges, during the last twenty years, certain plants of this re- 
gion, as delimited by the authors, appear conspicuous by their 
absence from the “flora.” Users of the flora will probably be 
disappointed not to find in it such common or striking plants of 
the region as the following: the braken fern, Pteridium aquili- 
num pubescens Underw., the most common fern in the “lower 
Woods,” Lycopodium annotinum L., L. Selago L., Erythronium 
montanum Wats., Salix scouleriana Barr., Spergularia rubra (L.) 
; ee Ranunculus bongardi Greene, Achlys triphylla (Smith) 
n Leptaxis menziesii (Pursh) Raf., Physocarpus opulifolius 
leas Spiraea lucida Dougl., Rosa gymnocarpa betel 
aie S e h L., Moneses uniflora (L.) Gray, and ‘m 
urak Saor Hook. Most of the weeds which have become nat- 
i ized in the openings in the lower forests of the region have 
€n omitted, perhaps intentionally.
