 This monograph, which no coastal plain botanist can afford to over- 

 look, combines the substance of several earlier papers on the same 

 subject, with the addition of considerable new matter and illustra- 

 tions. Reviewed by Upham in Am. Geol. 14:115-116. 1894.

 Several other papers by Dr. Merriam are often cited in modern phyto- 

 geographical works, but this one seems to contain the essence of 

 all of them. The fact that one of his ' ' life-zones ' ' coincides approxi- 

 mately with the coastal plain has obscured the true significance of 

 the latter in the minds of many botanists ever since. See Bull.
