must, therefore, be revisions. These species are provisionally accepted in The Cherries of New York 

 under the belief that botany and horticulture are best served by giving names freely so that all forms 

 to which reference may need to be made may thus be better identified. 



The botanical student of Cerasus is referred to Schneider's comprehensive discussion of Prunus in 

 his Handbuch der Lattbholzkunde 1:589-637. 1906 and 2:973-993; also Koehne's monographs of Cerasus, 

 Sargent, C. S., Plantae Wilsonianae Pt. 2: 197-271. 1912. Profitable though it might be, space does not 

 permit in The Cherries of New York a botanical discussion of other than the species cultivated for their 

 fruits.
