I. The Long-cluster Blackberries 

 Buhiis nigrobaccns 



The form which has somehow come to represent in 

 our minds the type of the species to which most of our 

 blackberries belong is designated by Professor Bailey 

 (Cornell Univ. Expt. Sta. Bull. 99:428) as the "Long- 

 cluster blackberry." This is the commonest form of 

 the wild blackberry found in low lands throughout the 

 eastern states. The berries are long and cylindrical or 

 thimble -shaped, with dull black drupelets, rather small 

 and closely packed on the receptacle. Each berry is 

 borne on a long, slender stem, which stands out some- 

 times almost at right angles to the main stem, and the 

 clusters are long, open and leafless. The leaflets are 

 rather long -stalked, evenly and finely serrate, and gen- 

 erally with a very long tapering point. 



Probably the best known representative of this class 

 in cultivation is the Taylor, though the Ancient Briton 

 aud the Early Cluster also belong here. 



As a matter of convenience, all varieties which it is 

 impossible to definitely classify at present are mentioned 

 here, though many of them, doubtless, belong else-
