Root with short spreading suckers. Shrub slender, with but little 

 branched stems, from eight to twelve feet long, the root shoots strong, 

 arched. Prickles strongly hooked, short, with a much dilated spread- 

 ing base, scattered on the stems, but mostly in pairs beneath the leaves 

 of the branches. Leaves with the common footstalk downy, sometimes 

 glandular, and bearing several slender prickles on the under side. 

 Stipules pale, thin, linear, with spreading points, the margins mostly 

 downy, often glandular, and serrated. Leaflets five to seven, ovate, 

 elliptic, or lanceolate, the margins simply, rarely doubly serrated, 

 bright green, and shining above, sometimes an opaque green, paler 

 beneath, smooth, except the mid-ribs on the under side being more or 

 less hairy, and sometimes a few scattered on the upper. Flowers rarely 

 solitary, generally numerous, in terminal bunches. Peduncles long, 

 slender, more or less numerously clothed with glands, or short selte, 

 of a glaucous reddish colour, as well as the lanceolate bracteas. Calyx 

 with a globose or oblong tube, smooth, rarely gland ulous or hairy, the 

 segments short, broadly lanceolate, with narrow tapering point, and 

 entire, or with a few slender narrow pinnae on the margin, smooth, or 

 uith a few glands, downy within, reflexed and deciduous before the 

 fruit is ripe. Petals obcordate, a delicate pale pink, yellow at the 

 base, sometimes white. Styles united into a column, usually pro- 

 truded, as long as the stamens, but sometimes almost included, smooth. 

 Stigmas forming a conical head. Fruit oblong, or globular, pulpy, 

 and of an orange red when ripe, smooth, crowned by the persistent 

 styles and the enlarged conical disk, of a pleasant flavour. 



Habitat.— Hedges and thickets, especially in the South of England, 

 and near Cork, Ireland. — Mr. Drummond.
