striated at maturity and of a clear dark reddish brown, having a light prunose 
bloom about the nodes, and occasionally scattering glandular spines, short and 
black, easily rubbed away; outer bark shedding second year in thin fibrous plates, 
oermanent bark checked coarsely; annual wood dense, sectionsl view showing rays 
numerous, with small pores between; nodes slightly bulging and bent? diaphragm 
1/10" to 1/8" thick, biconcave; bud broad at base, conical, acute, covered closely 
with reddtsh brown scales, beneath which is a layer of pale brown wool protecting 
the bud, whitish wool at summit, medium, pinkish or rosy in expanding, open tipped; 
tendrils intermittent, or occasionally several in succession. once or seldom twice 
forked, long smooth, red when young, brown when mature, persistent, clinging ;

somewhat enlarged at lower end, light brown. 
Leaves: Stipules minute, membranaceous; petiole, half the width of the 
blade in length, striated, usually smooth, with a very narrow pubescent groove on 
upper side, color generally red; blade 5" to 8", sometimes 10" to 11" broad by the
