» Description

Camellia rusticana Honda. First published in Biosphaera 1: 100 (1947). Sealy (1958), Rev. Gen. Camellia p.179 as C. japonica subsp. rusticana (Honda) Kitamura: Differs from C. japonica by shorter petioles, 5-8 mm. long and often pubescent on the upper side; by involucre of floral perules shorter, 1.5-1.7 cm. rarely 2 cm. high, inner perules smaller 1.2-1.5 cm. long and 1-1.6 cm. wide, perules from glabrous (slightly pubescent only at apex) in some flowers to densely appressed silky-pubescent with wide glabrous margins in other flowers; by petals less highly adnate to the androecium, usually for 4-6 mm. but sometimes for 7-10 mm., and wide-spreading; and by the shorter androecium, 1.7-2.3 cm. long, with filaments united among themselves for only 2-3 mm. above the union with the petals.  Distribution: JAPAN. Honsu : Yatsuo village, 17 km. S.W. of Toyama city (137° 7' E, 36° 55' N.), S.Kirino 162 (K, M); Muronaki village, 19 km. S.W. of Toyama city, S. Kirino 163 (K, M); Otaka Mt., Hosori village, 20 km. N.E. of Toyama city, L. A. Charette 1932m; Zaosan, Kitakanbaragun, Echigo Prov., M.Togasi, JVSM. 200 (K).

The leaf has a shorter petiole, about 5 millimetres long, with fine hairs (pubescent) at the base. The bracteoles and sepals are smooth (glabrous) on the outside. The color of the flowers ranges from red through rose to pink, flowering in April to May. 

In Japan it is known by the common name "yuki-tsubaki" (snow camellia) as it naturally occurs in areas of heavy snowfall at altitudes ranging from 1,100 metres down to 120 metres on sloping land under deciduous beech trees in the mountain regions to the north of the main island of Honshu and facing the Sea of Japan. In December heavy drifts of snow come in from the north, covering the plants to a depth of up to 2.4 metres. The bushes remain covered by snow from December till the end of March when the snow melts in early Spring and the camellias start flowering.
