rect, covered with soft to stiff whitish hairs. Stems several, branching from base. Leaf blades 1/3–1/2 in. wide. Basal leaf blades taper to margined petiole, together are 3–8 in. long; stem leaves smaller, sessile, sometimes clasping. Flowers on spreading branches at top. Flowers white or rarely blue, open wide, almost 1/2 in. across. Seed distinguished from H. micrantha by having more prickles on areas between margins.
