unifoliolate leaves. Flowers small, 0.87 to i inch broad, petals 

 one half as wide as long. Fruit globular, black, sweet and pulpy ; 

 drupelets rather large, more than 0.12 inch in diameter, i to 10. 

 Flowers late in June, fruits late in August. 



Type station, Alstead, N. H. Abundant over the large Bel- 

 lows Pasture on Signal Hill, two miles north of Forester's Mill. 

 On open land in dry ground. This is the only place I have 

 found where this dewberry grows, though a friend brought it to 

 me from a neighboring pasture. I first found it July 16, 1902, 

 and have collected it several times. Like Riilnis Jiispidns L., it is 

 a slender plant and tips well ; but that species is 3-foliolate and 

 has thick, shining, broad, short-pointed, cuneate-dentate leaflets 

 which survive the winter, and hispid bristles rather than weak 

 prickles, hugs the ground and branches freely, and in many 

 other ways is nearly the opposite of this species. 



The second dewberry is also of the Hispidiis group and has a 

 considerable resemblance to Rnhus jaccns. It is named and 

 described as follows : 



Rubus cubitans sp. nov. 



Plants prostrate, glabrous, nearly destitute of prickles, bristles 

 or glands, 5-foliolate, with thin, narrow, pointed leaflets, not sur- 

 viving the winter. 



Xeiv allies. — Stems slender, prostrate. 2 to 5 feet long, terete, 

 red, glabrous and glandless. Prickles {c\\\ weak, set at random, 

 slanting backward. Leaves small, 5-foliolate, glabrous, bright 

 green on the upper surface, a little lighter on the lower. Leaf- 

 lets narrow-oval, long-pointed, wedge-shaped at the base, finely 

 and doubly serrate-dentate. Petiole and petiolules slender, 

 grooved above, with slender, hooked prickles, the petiolule of the 

 middle leaflet about 0.5 inch long, those of the side ones short 

 and the basal leaflets sessile. 



Old canes. — Stems killed back but little. Second year's 

 growth entirely of leafy, erect branches or stemlets 4—6 inches 

 long, tipped with inflorescence, one from the axil of each old 

 leaf Axis of branches zigzag, terete, slender ; prickles very few 

 and very weak. Leaves 3-foliolate, the leaflets broad-oval, 

 rounded at the end, in color, serration and texture similar to 

 those on the new canes. Inflorescence a broad raceme 2 inches 

 long with 8—12 long, slender pedicels, glabrous, with occasional 

 weak bristles and glanded hairs, subtended by rather large bracts.
