Russia Flora: Plant: Up to 50 cm tall, usually growing on water body bottoms, rarely terrestrial (dwarf forms up to 20 cm tall); leaves arranged in basal rosette, usually with long petioles and leaf blades floating on water surface, deeply cordate, obtuse at apex; terrestrial forms with shorter petioles. Inflorescence: Panicle-like, on ± long leafless stems (scapes), with scale-like leaves and bracts at base of branches and pedicels. Flowers: Perianth of 6 segments. Sepals almost orbicular, greenish; petals broadly ovate, white. Stamens 6. Carpels 6-10, on almost flat receptacle. Fruit: Drupelets, 2.5-3.3 mm long (excluding style). (Table XXXI). Flowering in July-August. Protected.

Distribution: Lower Zeya (near Dep River mouth), Ussuri (Fig. 99). Found along water bodies, in marshes.

General distribution: Japanese-Chinese, South Asian. Described from Nepal.

Note: Differs from European C. parnassifolia (Bassi) Parl. in larger fruits and more obtuse leaf blade apex. However, in leaf blade shape, Far Eastern populations are intermediate between C. parnassifolia and South Asian populations of C. reniformis, and possibly belong to a yet undescribed third, East Asian species of this genus.
