 branches cylindrical, the younger ones marked with the ring-like 

 scars of the leaf -sheaths, and silky with long upward-pointing 

 yellowish hairs ; the growing extremities and young leaves densely 

 golden-silky. Leaves abundant, closely placed, alternate, 10 or 12 

 inches long when full grown, pinnate with 3 to 6 pairs of opposite 

 leaflets and an odd one, and, usually alternating with these, pairs 

 of very small leaflets ; petiole very broadly winged by the adnate 

 stipules, which are dilated at the base to form a broad sheath 

 embracing the stem, and terminate in short blunt ears ; larger leaf- 

 lets ovate- or lanceolate-oblong, 3 or 4 inches long, sessile and 

 unequally rounded at the base, acuminate at the apex, usually 

 overlapping, strongly and rather bluntly serrate, densely silky on 

 both surfaces when young, but becoming glabrous, except on the 

 veins below, and along the margin which remains strongly fringed.
