96 Rhodora [May 



tlentcite, 3-foliate, ii few .soinetiines unifoliate, small on the upper ones, 

 larger on those below. Flowers 1 to 1^ in. broad, ])etals long-oval at 

 least twice as long as wide with no apparent claw. Fruit nearly 

 globular, i to | in. in diameter, or on strong plants oylindric and larger, 

 sweet, drupelets black and rather larger than those of R. nigrobaccii..i, 

 Bailey. Flowers early in June and fruits early in August, productive. 



Type stations: Signal Hill and its northern borders in Alstead, 

 Cheshire County, N. H., being midway between Alstead Center 

 and Beryl Mt., Acworth; Thompsonburg in Londonderry, Athens, 

 Stratton and Windham in Windham County, Vt. Range as now 

 known to me; Southwestern New Hamjishire and Southeastern 

 Vermont. Elevated situations in open places on dry ground. Num- 

 erous specimens have been deposited by me in the Cray Herbarium 

 and in that of the N. Y. Botanical Garden. 



This pretty species which seems to be distinct from anything yet 

 described, I first found July 4, 1902, in Athens, Vt., on Bemis Hill and 

 I have watched it each season since. It grows in elevated situations 

 not occurring in the towns bordering on the Connecticut River. To 

 be specific, I have found it often abundant in Athens, Grafton, Jamaica 

 Londonderry, Stratton, Wardsboro and Windham, Vt., and in Acworth, 

 Alstead and Langdon, N. H., an east and west range of forty miles. 

 It blossoms and fruits the earliest of all blackberries in the localities 

 in which it grows. 



It is readily distinguishable from the other high blackberries by its 

 prim appearance, early fruiting and numerous slender prickles; from 

 the recurving class by its narrow leaflets and erect and furrowed stem ; 

 and from the setosus class by its strong prickles, lack of glandular hairs 

 and all the other characteristics mentioned in this paragraph. 



Rubus pergratus, n. sj). Large, erect plants more or less pubes- 

 cent, and nearly, or quite glandless, producing an abundance of large, 

 short-cylindrical, very edible fruit. 



New canes. Stems erect, 3 to fi feet high, large and strong, red and 

 glabrous, angled and furrowe<l. Prickles few, short, about ^ in. long, 

 strong, stout, 2 to 8 to the inch of stem, set at nearly a right angle to it 

 and on its angles only. Leaves of good size, often large, 5-foliate, 

 dark yellow-green and nearly glabrous on the upj)er surface, lighter 

 on the lower surface and pubescent. Leaves long-stalked, oval, often 

 broad-oval, the middle one sometimes ovate or nearly orbicular and a 

 trifle cordate, outline entire, finely often doubly serrate or serrate-
