plant is apparently common in Illinois and southward in the 

 Mississippi region. The cams usually lack the recurved and 

 willowy habit of B. nigrobaccus, and the absence of the villous 

 pubescence is marked. The leaflets arc often canescent below, 

 ami usually a little more coarsely toothed than in B. nigrobaccus. 

 In cultivation, the ]>Iant has given us Early Harvest, Brnnton 

 Early, Earliest of All, and perhaps Bangor; and the plant which 

 is cultivated as the Dorchester belongs to this species, bul 1 do 



not know it' it is the plant which was originally introduced 



under that name.

A form with very short and large-flowered clusters, the floral

 Mississippi. It has given mi cultivated varieties, mi far as I 

 know. ( Fig. W.

This plant has the general habit of B. nigrobaccus, but Is 

 lisguished by its long and Blender petioles, mostly narrow 

 long acuminate leaves, long stipules, and especially by its lack of 

 pubescence and i absence of thorns. It is apparently a 



well-marked Bpecies, growing throughout the country in the 

 higher elei in North Carolina northward.
