412 ICOSANDRIA-POLYGYNIA. Rubus. 



Root rather woody. Herb of a light green, slightly downy or 

 hairy, not hoary, throwing out a few very long, round, trail- 

 ing runners, either naked or leafy, taking root at the extremity, 

 where they, in the following spring, send u}d one or two simple 

 herbaceous flowering stems, from 3 to 6 inches high, which are 

 angular, slightly hairy, and often armed with a few small, weak, 

 spreading prickles. These stems bear 2 or 3 alternate, long- 

 stalked, ternate, serrated or notched leaves, not unlike those of 

 a Strawberry, the mode of growth of the two plants being also 

 very similar. Stipulas elliptic-oblong. Panicle terminal, corym- 

 bose, simple, downy, seldom a little prickly, of 3 or 4 upright, 

 small, greenhh-whlte Jlowers. Cut. angular at the basej its 

 segments oblong, downy within, externally somewhat hairy, 

 but not at all prickly or glandular ; spreading in Xhe^Jlower; in- 

 flexed, but not closely, in the fruit ; which consists of 1, 2, or 

 3 large crimson grains, agreeably acid, but not perfumed. 

 Seeds large, tumid, pitted, and elegantly wrinkled. 



By the above description, it is evident that this species can never 

 be confounded with any variety of the Dew-berry.
