1906] Blanchard, — Two new Species of Rubus 95 



TWO XE\Y SPECIES OF RUBUS FROM VERMOxNT AND 

 NEW HAMPSHIRE. 



W. H. Blanchard. 



Of the new species of Rubus, here described, both belong to the 

 high blackberry series. The first is a rather small and delicate sjiecies, 

 glabrous and glandless, with dark green leaves, small, early fruit, and 

 slender, strong, and often numerous prickles. The second is note- 

 worthy for its large and abundant fruit which is of excellent flavor. 

 The sjiecies may be characterized as follows: — 



Rubus elegantulus, n. sp. Plants from two to four feet high, very 

 erect and pretty. 



New canes. Stems very erect, 2 to 4 feet high, glabrous, red, well 

 angled and furrowed, rather small. Prickles on the angles only, slen- 

 der with a slight backward slant, strong and waspish to handle, about 

 12 to the inch of stem on typical ])lants but often less. Leaves thin, 

 small, 5-foliate, dark green above and slightly lighter below, perfectly 

 glabrous, or sometimes slightly hairy above and pubescent below, but 

 not appreciably so to the touch or to the unaided eye. Leaflets oval, 

 long taper-pointed; outline entire, finely and d<nibly serrate-dentate, the 

 middle one rather broad with rounded base and twice as long as wide, 

 the others wedge-shaped at the base and narrow. Petiole and petiol- 

 ules grooved above with three rows of hooked, slender, short and 

 strong prickles, the petiolule of the middle leaflet f of an inch long, 

 those of the side leaflets less than half as long, the basal leaflets sessile. 

 . Old canes. Erect as ever, prickles but little impaired, the cane pyr- 

 amidal in shape as in all true high blackberries. Growth of second or 

 bearing year consisting of leafy branches below ; above of racemes leafv 

 at the base with a straight axis, not a leafy branch tipped with a raceme, 

 one from each old leaf axil, or in many cases from two to four leafless 

 racemes. Inflorescence with a fine pubescence or none; peduncle 

 slender, pedicels very slender generally set at a great angle to the axis, 

 10- to IG-flowered, bracts small. True branches small, 6 to 10 in. 

 long, zigzag, nearly terete, glabrous, prickles hooked; leaves 3-foliate 

 at the base, leaflets broad and short-pointed; terminal ones 5-foliate 

 like those on new canes, all similar in color, texture and serration to 

 those on new canes. Leaves on racemes proper more coarsely serrate-
