Although small, the rich pink-purple flowers of maurandella antirrhiniflora
are quite easily noticed owing to the contrast with the larger, dark green leaves. The plant is a vine, with thin, twining stems that form tangled clumps, often attached to adjacent bushes for support. Leaves are also quite distinctive; broadly triangular, with bases that extend backwards, either side of the stalk. The long edges are slightly incurved in the middle. Stems and leaves are smooth and hairless.
Flowers are formed of a green, five-lobed calyx, and a tubular corolla (up to 3/4 of an inch long), opening to an upper lip divided into two closely-spaced lobes and lower lip of three more separated lobes. The lower lip is slightly raised at the center to form one side of the narrow, elongated opening at the throat. This central hump is white with purple flecks, and hairy. Flowers are borne singly at the leaf nodes. Calyx lobes are separate. The corolla tube contains four stamens, which are included, not protruding.
