176 " ' Rhodora [September 



Rubus Arundelanus, n. sp. Plants very pubescent with occasional 

 stalked glands on the inflorescence, the stems nearly terete, hard, 

 recurving and tipping. Leaves thick, the margins somewhat plicate; 

 those on old canes very irregular in form. 



New canes. Stems thick, glandless and glabrous, very smooth, 

 nearly terete, reddish green, hard, erect, 2 to 4 feet high, recurving, 

 often tipping, frequently branched. Prickles rather slender, strong, 

 straight, slanted slightly backward, I to ^% in. long, 5 to 10 to the inch 

 of stem, set in lines on the angles of the stem or pith. Leaves 5 to 7 

 in. long and wide, 5-foliate, thick; light yellow-green with numerous 

 hairs and rough on the upper surface, lighter with copious long pubes- 

 cence and very velvety beneath. Ijcaflets broad-oval or rhomboidal, 

 overlapping, outline wavy or slightly incised, margins somewhat 

 plicate, taper-pointed, dentate or serrate-dentate, the teeth narrow 

 and long with long points, the central tooth of the shallow lobes very 

 long; the middle leaflet very broad, often short-ovate approaching 

 orbicular, with sometimes a tendency to divide into three leaflets, 

 broadly rounded sometimes nearly cordate at the base; the side ones 

 broad-oval, oblique-angled at the base; the basal ones oval, broadly 

 cuneate. Petiole and petiolules large, faintly grooved, very hairy- 

 pubescent, glandless, prickles strong often large, recurved; the peti- 

 olule of the middle leaflet generally less than an inch long, the side 

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



Old canes. Stems reddish green, strong, hard to cut, prickles intact. 

 New growth consisting of leafy branches from 3 to 10 in. long tipped 

 with inflorescence, or rarely a pure leaf branch, regularly graded, the 

 slu)rt ones terminal, generally one from each old leaf-axil. Axis of 

 branches straight or often zigzag, angled, copiously pubescent with 

 occasional stalked glands; prickles numerous, rather large, strong 

 and somewhat hooked; leaves 3-foliate, the upper unifoliate, thick; 

 light yellow-green with some hairs on the upper surface, lighter and 

 very pubescent beneath; leaflets varying greatly in size and shape, 

 often very broad, irregularly and shallowly incised, coarsely dentate 

 or serrate toward the base, the unifoliate narrow or often broad and 

 deeply incised. Liflorescence on a short axis, cymose-corvmbose or 

 cymose-racemose; pedicels very pubescent with occasionally a stalked 

 gland, 6 or 8 set at a small angle or erect, and an erect one from the 

 axil of each lower leaf, subtended by unifoliate leaves and narrow 

 bracts, or some by nothing. Flowers appearing about July 1 large, 

 1\ to 1^ in. broad; petals broadly oval, one-half as wide as long; 

 sepals broad, very pubescent, mucronate or acuminate. Fruit ripen- 

 ing about Aug. 10 and continuing in fruit about two weeks, globose, 

 i in. in diameter, diaipelets large, j^ in. in diameter.
