Plants form small, compact mats from a multi-branched woody base (caudex). Plants are not stoloniferous (horizontal stems along ground surface).
Compactly arranged; narrow to linear and sometimes broadest in the upper half; with dense, silky hairs.
Plants have either all female (pistillate) or all male (staminate) flowers (= dioecious). A single head containing several flowers terminates the leafy stems. Staminate heads 5-7 mm. high and appear blackish-green; pistillate heads 10-15 mm high and appear brown to reddish-brown.
