A NEW RUBUS FROM CONNECTICUT. 

 W. H. Blanchard. 



Rubus Andre wsianus, n. sp. Plants pubescent with frequently a 

 few stalked glands on the inflorescence and remarkably long, stqut 

 and numerous prickles. Inflorescence ending leafy branches. 



New canes. Stems erect or recurving but never reaching the ground, 

 3 to 5 feet high, stout, often | in. in diameter, reddish on the upper 

 side; branched in rich open places, glabrous, strongly 5-angled and 

 furrowed. Prickles \ of an inch long, 7 to 15 to the inch, straight, 

 perpendicular to the stem and on its angles only. I.,eaves of moderate 

 size, 8 in. long and 7 in. wide, 5-foliate, dark yellow-green above with 

 numerous appressed hairs, lighter below and velvety to the touch with 

 abundant appressed pubescence. Leaflets oval, the middle one some- 

 times slightly cordate; outline entire, finely and doubly serrate-dentate, 

 short taper-pointed, the upper ones rounded at the base, the basal ones 

 cuneate, rather thick, about twice as long as wide, the middle one 

 slightly wider. Petiole and petiolules grooved, stout, glandles, cov- 

 ered with long soft pubescence and numerous strong hooked prickles 

 in three rows continued in one row on the midrib; the petiolule of the 

 middle leaflet about an inch long, those of the side leaflets about one- 

 third as long, and the basal ones sessile. 



Old canes. Erect, not pulled down by snow or weight of foliage 

 or fruit, prickles intact. Second year's growth entirely of leafy 

 branches generally one from each old leaf axil, somewhat zigzag, 

 tipped wdth the inflorescence. Branch stems terete, slightly pubes- 

 cent, prickles straight, slanting backward. Terminal branches 4 to 

 6 in. long with leaves mostly 3-foliate, some unifoliate, and ending in 

 a short raceme pubescent with frequently a few stalked glands inter- 

 mixed, quite regular, an inch long with 8 to 12 flowers on slender 

 pedicels an inch long or less set at a great angle to their axis. Bracts 

 small, never leafy-bracted. Lower branches often 20 inches long, 

 the numerous leaves mostly 3-foliate occasionally 5-foliate, inflores- 

 cence scanty or wanting. Intermediate branches increasing regu- 

 larly in length downwards and the amount of inflorescence on their 

 tips as regularly decreasing. Leaflets oval or ovate, generally 

 rounded at the base, pointed, the middle one stalked; outline
