Flora of North America species comparison

flowering stems ascending, branched, 15–40 cm; nonflowering stems prostrate proximally, rooting readily, pubescence dense, white-tomentose, eglandular; small axillary tufts of leaves often present.

flowering shoots ascending, often decumbent at base, branched, (15–)25–35(–40) cm, softly pubescent to subglabrous, hairs spreading, straight, concentrated in longitudinal lines toward base, glandular and eglandular; nonflowering leafy shoots often present, straggling, 5–15 cm; small axillary tufts of leaves present.
