gray, distinctly platy, plates scaly.

dark gray, deeply furrowed, ridges long, scaly-plated.

nearly whorled, spreading-ascending;

twigs slender, pale red-brown, rusty puberulent and slightly glandular (rarely glabrous), aging purple-brown or gray, smooth.

spreading-ascending, often contorted;

twigs stout to slender, orange-brown, aging darker brown, rough.
