形態特徵

Rhizome short, elongate, bearing leaves and flowers at regular intervals.
Petiole-like shoots with several nodes, simple, flexible; nodes occasionally rooting. Petioles 1-2.5 cm long; leaves few per node; blades orbicular-rounded, 1-6 cm across, deeply cordate at base with narrow sinuses, purple on abaxial surface.
Flowers 2-10 per node, 5-merous. Pedicels 3-6 cm. Calyx deeply 5 lobed; lobes narrowly lanceolate. 3-5 mm long. Corolla white with a yellow throat, campanulate. Corolla tube 7-8 mm long, lobes 5, oblong, with flexous, membranous wings on the margins and a similar median longitudinal crest within. Stamens as many as petals, inserted at the sinuses of the corolla, each with a small tufts of glandular bairs. Pistil bottle-shaped, with 5 hypogynous disc glands, orbicular, cililolate at tips wilh papillose hairs.
Capsule oblong, 3 mm in diameter, 1-6-seeded. Seeds globose, ca. 2 mm in diameter, densely covered with many short papillose projections.
Chromosome number 2n = 18. <li>The present species has long been named under Nymphoides cristota (Roxb.) O. Kuntze. Sivarajan and Joseph (1993), Toyokuni and Yamazaki (1993), and Cook (1996) treated N. cristata as a synonym of N. hydrophylla, but Ho & Ornduff (1995) and Yang et al.(2001) could distinguish them and N. cristata is also distributed in Taiwan. Whether these two entities should represent distinct species are open to debate. Since the Taiwanese materials can fit N. hydrophylla by Sivarajan and Joseph's publication, here we tentatively treat them as the same species.</li>
