 I have often received from Massachusetts, and other parts of 

 New-England, a Ribes, which appears to be a variety of the 

 preceding. The following are its characters : — 



Subaxillary spines solitary. Leaves on slender villous petioles, 

 canescent-villous or pubescent, somewhat 5-lobed, with the 

 lobes rather obtuse and incisely toothed. Racemes loose, 

 3 — 5 -flowered ; fiedicels long, flexuous ; bracts short, dentate- 

 ciliate. Segments of the calyjc erect, lanceolate, acute. Pe- 

 tals short, ovate. Style hairy at the base, a little exserted, 

 2 — 3-cleft. Berries ovate, purplish-brown, aculeate-hispid. 



This may possibly be R. Cynosdad, but the subaxillary 

 spikes are solitary.
