with wiry decumbent stems spreading to form loose mats up to 30cm across or more, by 10-20cm tall. Leaves almost scale-like, densely overlapping, 3mm or more long, white downy. Flowers about 6mm across, bright yellow, summer. New Brunswick to North Carolina, west to the Great Lakes, in sand dunes and sandy woods (pine barrens). H.t. var. intermedia covers plants which are more or less halfway between H. tomentosa and H. ericoides. Some botanists see all three species described here as one variable species, and this seems to be a more sensible approach to the genus.
