Inflated lady's-slipper

Family: Orchidaceae. It occurs in deciduous and mixed forests, on forest glades in the temperate zones of the European part of Russia, Siberia, the Far East, reaching the Kuril Islands, northeastern China and Japan.

Plants up to 40–45 cm tall. Rhizome somewhat thick, short. Stem erect, slightly pubescent. Leaves 3–5, broadly ovate, acute, sparsely hairy, 15 cm long and 5–7 cm wide. Flowers large, solitary, with large leaf-like bracts. The dorsal sepal is elliptic (narrower than in С. macranthum Sw.), long-acuminate; the lateral sepals are fused into a single two-toothed structure. Petals long, narrow-lanceolate, longer than the lip, drooping. Lip elongate-ovate, somewhat flattened on the sides. The color of the lip, sepals and petals is almost the same — brownish-reddish, pale, sometimes white; the lip has a faint marbled pattern. Blooms in summer. Highly ornamental.
