A small shrub usually 3-5 feet high ; branches slender erect-patent, 

 straight or somewhat curved at their base, covered with a crowd of stellate 

 hairs with long multicellular pedicels, castaneo-brown when young, changing 

 to grayish white as they become old by the development of corky bark. 

 Scales at the base of young shoots arranged in four longitudinal rows; 

 lowest pairs shortly ovate, upper ones lanceolate, both being acuminate, 

 rigid and hirsute on the back, persistent : uppermost pairs linear lanceolate, 

 membranaceous, of a brown color, hirsute on the back with ascending 

 hairs, deciduous. Floral branches very short, growing out from the axillary 

 buds of the branches of the last year, with or without a pair of leaflets 

 at their base. Leafy branches 2-4 inches long with 3.-4 pairs of leaves. 

 Leaves at the time of flowering about 1 inch long, those at the time of 

 maturation of fruit more than twice as long. Petiole about -J inch long, 

 channeled on the upper surface, with scattered 3-4-rayed stellate hairs all 

 over. Blade more than twice as long as the breadth, ovate-lanceolate or 

 oblong-ovate, rounded or shortly cuneate at the base, acute or acuminate, 

 densely serrulate at the margin except the cuspidate apex, with scattered 3-4 



id stellate hairs on both surfaces; the form of stellate hairs of the 

 upper surface being regular and that of the under surface often being 

 irregular. Peduncle terminal to the very short lateral, unifloral, -J inch 

 with 1-3 subulate bracts. Calyx * inch high, tubular portion 

 powdery with minute stellate hairs; limbs glabrous, almost equal in length 

 Lube r longer, triangular or subulate, persistent. Petals about 3
