Maianthemum dilatatum (A. W. Wood) A. Nelson & J. F. Macbride (Bot. Gaz. 61: 30. 1916), from Japan, Mongolia, E Russia, and NW North America, probably occurs in China. In Russia and Japan, M. dilatatum is sympatric with M. bifolium and, in Japan, there occur intermediate forms which may have derived from hybridization between the two species (Kawano, pers. obs.). Such plants in the Russian Far East have been called M. intermedium Voroschilov (Izv. Glavn. Bot. Sada RSFSR 38, 50. 1960) and may also occur in China.

Maianthemum bifolium
provided by wikipedia EN
Maianthemum bifolium (false lily of the valley or May lily[1]) is often a localized common rhizomatous flowering plant, native from western Europe (including Britain[2]) east to Siberia, China and Japan.[3]
Non-flowering stems usually have only one waxy leaf, but on flowering plants there is one basal leaf that withers away before flowering, and two stem leaves produced alternately up the 10–20 cm tall stems, which are topped off with many star-shaped white flowers. The leaves are heart to triangular, 3–8 cm long and 2–5 cm broad, with small fine hairs on the veins. The flowers have four tepals, four stamens and have two chambers in the pistil; flowering is in mid spring to early summer. This species, along with Maianthemum canadense and Maianthemum dilatatum are the only four-tepaled species. One to two seeds are produced in round berries that are speckled red when immature and redden with age. This species is found in the wild growing in open forests and on damp soils in grassy ditches and thickets.
