Rhizome sometimes with a metallic blue-gray color, 0.5-1 cm in diam., irregularly thickened. Root system sometimes with many finely branched upright roots. Leaves green to brown, very variable, narrowly linear to lanceolate, 10-70 × 0.2-4 cm, smooth to undulate to bullate, margin entire to finely, irregularly denticulate; broader leaf blades mostly with conspicuous lateral veins. Generally, two ecological leaf forms occur: 1) plants that grow submerged for most of year, thus developing long flaccid-lax submerged leaves (sometimes also developing shorter, stiffer emergent leaves); 2) plants that develop short terete leaves during rainy season and, when water level decreases, form normal emergent leaves at anthesis. Spathe outside greenish to brownish, 10-40(-60) cm; kettle 1-2.5 cm, inside somewhat constricted below male flowers, inside ± reddish (especially distally) and with alveolae (depressions in wall) in distal part; flap closing kettle sometimes ± purple spotted; tube slightly to somewhat twisted, 5-30(-45) cm; limb ± spirally twisted, yellowish to grayish, with short to long, purple to reddish markings, sometimes markings almost completely covering surface, or few and faint, or absent, (1.5-)3-8(-12) cm; collar not present. Spadix: female flowers 4-6, with horizontal to vertical, round to ovoid stigmas; olfactory bodies ± irregularly lobed with protruding cells; male flowers 90-130, thecae rough from protruding cells. Fruit splitting in a septicidal/septifragal-ceratium-like way, greenish to purplish, narrowly globose, 1-1.5 cm, smooth. Seeds brownish, 5-8 mm, rugose; endosperm present; embryo cone-shaped with an undifferentiated plumule. 2n = 36, 54.

Cryptocoryne crispatula s.l. is here interpreted as one species comprising different ecological races, i.e., leaf forms that are adapted to the water supply and the overall topography of the rivers in which they grow. In rivers with more constant water-bearings, and not too steep a fall, the more aquatic ones occur, viz. the long, narrow-leaved forms with an undulate or bullate leaf blade. In rivers with a seasonal variation in the water-bearings, the more amphibious ones occur, characterized by having shorter, ± smooth leaves. The variation within C. crispatula is very complex, with more than six recognizable forms in mainland Asia, some more readily distinguishable from the next than others. There are transitions between the various forms. The here recognized varieties represent the more distinctive ones, and admittedly specific plants may only with some difficulty be referred unambiguously to a definite variety. The number of varieties accepted is subjective. This is not meant as an excuse for an insufficient treatment but is merely recognition of the complexity of C. crispatula.Cryptocoryne crispatula s.l. is here interpreted as one species comprising different ecological races, i.e., leaf forms that are adapted to the water supply and the overall topography of the rivers in which they grow.
