description
Pseudosindora palustris grows as a tree up to 30–40 meters high. The trunk diameter can reach 180 centimeters. The bark is easily cracked.
The short stalked, short leaves are alternately (unpaired) pinnate with 3 to 6 leaflets . The short-stalked, rounded, pointed to pointed, bald, leathery leaflets are ovate to elliptical and have entire margins. They are about 5-14 centimeters long with a brownish leaflet stalk about 5 millimeters long. There are smaller, sloping stipules . The first pair of leaves on young plants is opposite, later they are alternate.
The short, slightly rusty hairy and paniculate , axillary or terminal inflorescences are up to 11 centimeters long. The grouped flowers with a simple perimeter are petiolate, the petals are missing. The inside hairy, 5 millimeters long, whitish, petaloid and leathery sepals are laid back and slightly boat-shaped. The 10 free stamens are alternately longer or shorter. The upper permanent ovary is stalked, with a slightly (to) bent stylus with smaller capitate scar .
There are pointed, leathery and 4.5–6 cm long, elliptical legumes with few seeds. The 1–2 seeds are 2.4–2.7 centimeters long and ellipsoid, glossy dark brown or blackish and encompassed by a two-lobed, fleshy, large and reddish aril .
