Cabomba schwartzii is a species of aquatic plant in the family Cabombaceae endemic to North Brazil.

Description

Vegetative characteristics

Cabomba schwartzii is an aquatic herb. The length of the stems depends on the water level. The stems have two vascular bundles. The elliptical or orbicular, peltate, petiolate floating leaves are 1.5—3.8 cm long, and 1.0—2.5 cm wide. The adaxial leaf surface is purple. The petiole is 1—3 cm long.

Generative characteristics

The yellow flowers emerge above the water surface. The 2-3 sepals are 6.0–8.0 mm long, and 2.5–3.0 mm wide. The 2-3 petals are 6.5–8.0 mm long, and 2.5–3.0 mm wide. The androecium consists of 2, 3, 4, 5, or 6 stamens. The gynoecium consists of 1, or 2 carpels. The seeds are 1.5–2.2 mm long, and 1–1.2 mm wide.

Taxonomy

Cabomba schwartzii Rataj was published by Karel Rataj in 1977. It was then treated as a synonym of Cabomba aquatica Aubl. by Marian Ørgaard in 1991. It was reestablished by Barbosa et al. in 2018. The type specimen was collected by T. W. Schwartz in Igarapé do Aduja, Rio Itu, Rio Negro, Brazil.
