1906] Blanchard, Some Maine Rubi,— I 155 



bunk Beach, Maine. A very abundant plant in roads, moAvings and 

 pastures in Wells, Kennebunk and Kennebunkport. Also in Bidde- 

 ford and Old Orchard. Open ground and light shade. 



The writer first noticed this plant in 1904 and doubtfully referred 

 it to R. recurvana, but its distinctness soon became evident with more 

 observation. The lack of pubescence and comparative lack of prickles 

 are alone sufficient to distinguish it from that plant, while its tendency 

 to blacken in drying seems to be greater than that of any other black- 

 berry. 



Var. inarmatus, n. var. Plants large-stemmed, glabrous, glandless 

 and nearlv unarmed, H to 2 ft. high, recurving and the long slender 

 end tipping. Leaves 5-foliate, thick, the earlier ones very large. 

 Infiorescence an irregular cyme; flowers very large and showy, from 

 1| to If in. broad, petals wide; fruit globose, \ in. in dameter. 



New canes. Stems erect, l\ to 2^ feet high, thick at the base, 

 brown, soft, recurving with a long, slender prostrate end,_ ti])ping m 

 September, slightly angled, glabrous and glandless. Prickles very 

 few and small, often none, straight, set on the angles of the stem or 

 pith. Leaves thick, those appearing early very large, smaller beyond, 

 vellow-green and glabrous on the u])i)er surface, paler beneath and 

 apparentlv glabrous, but with an aj^pressed pubescence, not ciliate, 

 5-foliate. ' Leaflets broad, short taper-pointed, outline entire, finely 

 antl doubly serrate-dentate; the middle leaflet very broad, often 

 nearly orbicular and approaching cordate; the side ones broad also, 

 rhomboidal, broadly cuneate; the basal ones similar in sha]K> but 

 smaller. Petiole aiul petiolules large, glabrous, yellowish, prickles 

 wanting; the petiolule of the middle leaflet about 1 in. long, the side 

 ones one-fourth as long, and the basal leaflets sessile. 



Old canes. Stems much uearer the ground, reddish brown, soft, 

 iirickles entirelv wanting. Xew growth consisting entirely of leafy fruit 

 branches 4 to" S in. long, or rarely a branch without inflorescence, 

 generally one from each old leaf "axil, fretpiently several. Axis of 

 branch green-vellow, angled, unarmed, finely pubescent, zigzag. 

 Leaves of good size, coarse texture, 3-foliate; some on the infl()res- 

 cence unifoliate; glabrous and yellow-green on the upper surface, 

 light and faintly pubescent beneath. Leaflets narrow-oval, long; 

 pointed at each end, rather coarsely and doubly serrate, nearly dentate 

 toward the point; the unifoliate leaves mostly very broad and deeply 

 2-incised, approaching trifoliate. Petiole short, stout, grooved, un- 

 armed, pubescent, the petiolule similar; the middle leaflet short- 

 stalked, the side ones sessile. Inflorescence cymose approaching 

 racemose, pedicels 4 to G, rather long, slender, glandless, slightly 

 pubescent, subtended by small l)racts. Flowers very large, from 

 If to If in. broad; the petals wide, measuring from \^ in. long by -^^ 

 in. wide to \l in. long by A i". wide; sepals abruptly narrowed to a
