growth, and * * * in the earliest stages examined there 



were always two foliar tubercles, one of which speedily overpassed 



the other, so that ultimately all traces of the second leaf were 



obliterated. The monophyllous sheath of this pine therefore 



owes its pecuUarity to the generally arrested development of 



one of its two original leaves."

Plants of Nantucket. — Maria L. Owen. (Pamph., 8vo,, pp. 87, 



1888.) 



This addition to the list of local plant catalogues is a model 

 for all of its kind. Its appearance is a credit to the printer, and 

 the contents bear every evidence of careful field work and pams- 

 taking compilation by the author. Its value does not alone con- 

 sist in an accurate list of the plants, but also in the many notes, 

 memoranda and local names which are interspersed throughout, 

 giving just the authentic information that will be appreciated by 

 the botanist of the future, when many of the plants now noted 

 have become exterminated. Due credit is given to all who tiave 

 assisted in the work, either voluntarily or unwittingly, and the 

 modesty of the author is not its least pleasing feature. Indeed, 

 almost the last words in the cataloP"ue are words of regret that it

could not be made more complete by a record of the lichenes 

 and fungi. Four hundred and seventy native and one hundred 

 and sixteen introduced species of flowering plants are named, 

 besides fifty varieties, both native and introduced. Twenty 

 species of Pteridophyta are enumerated. The species of Marine 

 Algae number one hundred and ten, of which two are said to be 

 ''new to America'' and four " not in Farlow's Manual" The 

 Characeae number ten species, but only six Mosses and two 

 Hepatics are mentioned, and doubtless many additions could be 

 made to these latter two orders, in spite of the fact that we are 

 told "The Island does not seem to be rich in these orders." 



Any review of the flora of Nantucket would necessarily be 

 incomplete without at least a brief mention of its exceedingly 

 interesting introduced species. Many of them have never been 

 naturalized elsewhere in America, and fortunately they seem to 

 have fallen amongst good friends. Thus in regard to Erica 

 cinerea, L. : '* The place is also known now to several persons
