1906] Blanchard, — Two new Species of Rubus 97 



dentate, taper-pointed, rounded at the base or the basal leaflets broadly 

 wedge-shaped. Petiole and petiolules stout, grooved above, nearly 

 or quite glabrous, glandless, with a few hooked, strong prickles; the 

 petiolule of the middle leaflet 1 to 1^ in. long, those of the side leaflets 

 over one-half as long, the basal leaflets never sessile. 



Old canes. Still erect, pyramidal, the prickles intact. Second year's 

 growth consisting of nearly leafless racemes at the top of the stem, 

 succeeded downward by racemes leafy at the base, and these in turn 

 succeeded by pure leaf branches. Stems of leaf branches irregularly 

 angled, 8 to 12 in. long, more or less pubescent, even woolly on somie, 

 prickles small and hooked; leaves 3-foliate at the base of each branch, 

 5-foliate beyond, resembling those on the new canes, but broader and 

 more pubescent. Racemed branches or fruit branches with a stout 

 axis, irregularly angled, pubescent or woolly, prickles short and re- 

 curved; leaves 3-foliate and unifoliate; leaflets very broad and pubes- 

 cent, coarsely serrate-tlentate; about 8 to 12 stout pedicels, very 

 pubescent often woolly with sometimes a stalked gland, set at a mod- 

 erate angle to the axis, subtended by small bracts; raceme broadest 

 at its top. Naked racemes similar. Flowers large and showy, 1\ to 

 1^ in. broad, {petals wide, width two thirds of the length, opening the 

 middle of June. Fruit very large short-cylindric, drupelets large and 

 pulpy, sweet; seeds small and unnoticeable. Very productive. Re- 

 sembles some cultivatetl kinds. Ripe early in August. 



Type station Alstead, N. H., one mile east of Signal Hill. Abun- 

 dant there and in the elevated parts of Windham County, Vt. 



Two other stations where I have found it very abundant and perfect 

 are the lower slopes of Glebe Mt., Londonderry and in South Wind- 

 ham, Vt., though I have found it equally perfect in many other places. 

 It shows its characteristics best in open sun while in moist, rich shade 

 where it grows very tall and leafy its distinguishing features are some- 

 what obscured. 



This blackberry which I have been watching since 1902 closely 

 resembles Nome of those now in cultivation. It is called by the people 

 living where it grows the "square blackberry," and the "short black- 

 berry," in distinction from the "long blackberry" and the "sheep-teat" 

 and "sow-teat," three well-known names for R. nigrohaccus, Bailey. 

 In the immediate valley of the Connecticut River where I live, R. 

 nigrohaccus is very abundant and is the only "high" blackberry the 

 people know; but as you get away from the river and into more ele-
