The two series for 1900, in my regular distributions, will be from above regions: 

 Series I. in a single lot, Series II. by centuries ; the latter will be the first eastern sets 

 distributed from Dr. Greene's determinations. The 1899 series from southwest Col- 

 orado and northwest New Mexico, contain many extensions of range, new determina- 

 tions, and several hundred new species. Fungi, Mosses and Lichens will be sold 

 separately. 



Exchanges will be made only for plants of west North America, West Indies, Ontario and South 

 America, and for papers not in my library. Regular subscribers need not reply to this ad ; sets will be 

 reserved for them as usual. All others should address at once
