150 Rhodora [August 



5-foliate, noticeably yellow, the leaflets with conspieuously ])laite(l 

 or ruffletl margins. Tipping reatlily. 



Nciv cancf. Stems prostrate, 4 to (5 feet long, greenish, terete, 

 glal)roiis and glandless, often branched, the ends swelling late in 

 August and readily tipping. Prickles long, slender, rather strong, 

 straight with a backward slant, never hooked except near the tipping 

 end, not numerous, 5 to 10 to the inch of stem, not noticeably in lines. 

 Leaves rather large and thick, 5 to () in. long and wide; normally 

 5-foliate but often 3-foliate on early growth; noticeably yellow; light 

 yellow-green and j)erfectly glabrous on the upper surface, lighter 

 below and slightly pubescent, with hairs on the large veins; slightly 

 ciliate. Leaflets oval, outline entire, taper-pointed; deeply, finely, 

 sharply antl somewhat doubly serrate-dentate, the base entire, the 

 margin remarkably wavy-plaited or ruffled; the middle leaflet very 

 broad, frequently nearly orbicular, often 2^ in. wide; the side leaflets 

 one-half as wide as long, cuneate at the base; and the ba.sal ones 

 smaller but having the same ])rop()rtion. Petiole and petiolules 

 rather slender, yellow, s])aringly pubescent, grooved; prickles slender, 

 strong, slightly hookeil; the ])etiolule of the middle leaflet f in. long, 

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



Old canes. But slightly killed back, prickles much broken. Growth 

 of second year consisting of erect branches; occasionally a pure leaf 

 branch, mostly fruit branches, 3 to G in. high, those near the base of 

 the cane longer and more leafy than those nearer the extremity, gen- 

 erally one from each olil leaf axil. Axis zigzag, irregularly angular, 

 yellow, pubescent, glandless; j)rickles few, weak, straight and slender. 

 Leaves very small, 3-foliate, those on the inflorescence unifoliate; in 

 color and texture like those on the okl canes, but more pubescent. 

 Leaflets oval, pointed at both ends, deeply serrate-dentate with in- 

 curved teeth, the margins plaited or ruffled. Petiole and petiolules 

 yellow, pubescent; jirickles slender and few, nearly straight. Inflores- 

 cence a broad raceme, the axis 1 to 1^ in. long with 6 or 8 pedicels set 

 at a great angle to the axis, pubescent but glandless. Flowers rather 

 large, 1^ in. broad; petals oval one-half as wide as long; sepals very 

 pubescent or woolly, mucronate; a]i]>earing about July 1. Fruit 

 short-cylindric, not globose, about f in. high and ^ in. wide with large 

 dru])elets 2^ to 3 sixteenths inches in diameter. Four measured and 

 counted: f in. high by ^ in. wide 2S drupelets; \^ in. by j\ in., 27 

 drupelets; \^ in. by f in., IS drupelets; f in. by | in., 20 drupelets. 

 Very productive; ])icking season from August 1 to August 15. 



Type stations: The railroad depot at Wells Beach and the highway 

 thence to KennelMuik village, Maine. Very abundant in various 

 places in Wells, Kennebunk anfl Kennebunk])ort. Also in North 

 Berwick. Open places, especially in sandy ground. 



The plaited or ruffled margins of the leaves of this plant make it
