An efarinose species, shallow rooted, leaves oblong to broadly ovate, 1.5-3.5cm long, pilose above and below, apex rounded, base cordate (rarely subrounded) and with a densely pilose petiole 2-5cm (longer than blade). Scapes 2.5-5.5cm sparsely pilose with 2-6 pink flowers. Calyx campanulate, glabrous, parted to middle, lobes narrow-triangular, margin hydathode-apiculate. Capsule operculate.
