is a petal-lacking perennial that inhabits forests in mountainous
regions. Stems grow crawling on the ground to set a pair of opposite
phyllotaxis leaves at the terminal. The leaves are oval
heart-shaped, 4-8cm long, with short white hairs on both sides. This
species set single-purple-brown, 1.5cm-in-diameter flowers at the
bases; the sepals bend backward outside at the halfway point to
adhere to their own lower portions. Bloom time: March-May.
