Utricularia cymbantha Ex Oliv.

Very small, annual, suspended aquatic. Rhizoids absent. Stolons capillary, branched, up to 10 cm long or longer, c. 0.2 mm thick, glabrous. Leaves very numerous at internodes of 1-2 mm, forked from the base into two, equal or unequal, curved, capillary, apically minutely setulose segments, the segments either both 0.5-0.8 mm long or with one much longer, up to 2.5 mm. Traps numerous, in the angle between the leaf segments and also laterally near the apex of the longer segments, ovoid, 1-1.5 mm long, stalked, the mouth lateral with two dorsal, branched, setiform appendages and further ventral, shorter, simple setae, the internal glands 1-3-or rarely a few 4-armed, the arms mostly short, pyriform, apiculate, 2-4 times as long as wide, the arms of both the bifids and quadrifids widely divergent with an included angle of 80° to 90°; all the vegetative parts and the peduncle, pedicels and bract ± densely covered with minute sessile glands. Inflorescence erect, emergent, 0.4-1.5 cm long, arising at variable intervals along the stolons; peduncle filiform, terete, 0.2-0.3 mm thick. Scales absent. Bracts basifixed, narrowly ovate, c. 1 mm long, membranous, nerveless; bracteoles absent. Flower apparently always solitary; pedicels capillary, terete, up to 8 mm long, erect in flower, strongly decurved in fruit. Calyx lobes subequal, c. 1 mm long, membranous, nerveless, the upper lobe broadly ovate, the lower lobe circular, both with the apex rounded. Corolla 3-5 mm long, white or cream; upper lip transversely oblong, with apex rounded or emarginate; lower lip limb approximately circular or subreniform, concave when viewed from outside, the apex rounded, or emarginate; palate ill-defined; spur saccate, approximately hemispherical, the inner surface (and the central part of the lower lip limb) ± densely beset with minute rosette-shaped sessile glands. Filaments curved, c. 1 mm long, the anther thecae confluent. Ovary ovoid, ovules 3 or 4; style filiform, distinct; stigma lower lip elliptic with apex rounded or emarginate, ciliate, the upper lip ± obsolete. Capsule ovoid, c. 1.5 mm long, the wall membranous, apparently indehiscent. Seeds 2 or 3, lenticular, circular, c. 0.7 mm wide including a narrow, irregularly minutely denticulate wing, the testa cells irregular, small, ± isodiametric on the distal surface, elongate on the proximal surface, the anticlines ± straight, raised, thickened and somewhat irregularly rope-like, the periclinal walls tabular, microscopically rugose with distinct transverse ridges.
