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 stems erect from decumbent base, branched proximally, 10–45 cm, softly pubescent, eglandular with straight hairs; nonflowering shoots, when present, produced proximally, decumbent, rooting at nodes, branched, 5–20 cm, often subglabrous with alternating lines of eglandular hairs; small axillary tufts of leaves usually absent.
