The Plant World 



The only non=technical periodical devoted exclusively to this branch of biology 

 and dealing with all phases of plant life. 



PROSPECTUS FOR THE NEW YEAR. 



Each issue of Volmne lY, commencing in January, 1901, will be 

 enlarged by four additional pages, and the special features of the vol- 

 ume will be as follows : a department of notes and suggestions for 

 teachers ; articles descriptive of the various groups among the lower 

 plants, illustrated by luU page plates ; series of articles by prominent 

 botanists recounting their collecting experiences in such countries as 

 Cuba, Porto Rico, Alaska, etc. ; discussions of important economic 

 plants ; book reviews, and general items. The eight-page supplement, 

 devoted to a systematic account of all known families of flowering 

 plants, which has been such a valuable feature of the past volume, will 

 l3e continued and even more freely illustrated. Many of our subscrib- 

 ers have voluntarily testified to their appreciation of The Plaot? "Woeld, 

 but the words of Professor Charles E. Bessey, of the University of Ne- 

 braska, are particularly gratifying to us, and should be remembered by 

 everyone who contemplates taking a botanical periodical. He says, 

 " The PlajSTT Woeld has made a place for itself, and I cannot afford to 

 be without it." 



The Asa Ghray Bulletin, a journal now in its eighth volume, dis- 

 continued publication with the December issue, and will henceforth be 

 merged in The Plajstt Woeld. Mr. Cornelius L. Shear, formerly an edi- 

 tor of the Bulletin, has joined the editorial board of The Plant Woeld, 

 and will have charge of the cryptogamic articles and the teachers' de- 

 partment. Former readers of the Bulletin will gain much by subscrib- 

 ing to The Plaict Woeld for 1901. 



Subscription $1.00 per year. 



Sample copy free on receipt of a one cent stamp. 



We still have on hand a limited number of Volumes I and 11. It 

 is important that you should complete your set. We have not in- 

 creased the price on these volumes, and they will be sent postpaid for 

 81.00 each. We have also acquired the entire stock of back numbers of 

 the Asa Ghriy Bulletin, prices of which will be furnished on application.
