description
Walsura pinnata grows as an evergreen tree to over 20 meters high, it should be up to 37 meters high, or as a shrub up to about 4 meters high. The trunk diameter reaches up to over 60-75 centimeters.
The alternate and stalked leaves are unpaired pinnate with up to 7 leaflets and the 20-30 cm long rachis is thickened at the leaflet base, or the leaves are reduced, with only one leaflet (unifoliolate). The almost bare leaf stalk is up to 10 centimeters long. The entire, egg-shaped to elliptical or obovate and almost glabrous, short-stalked, slightly leathery leaflets are pointed to tails or pointed. The leaflets of the pinnate leaves are about 8-25 centimeters long. The leaflet stalks, with pulvini at the tip, the lateral leaflets are up to 1.5 centimeters long, those of the terminal leaflets up to 3.5 centimeters. The unifoliate leaves are up to 9 centimeters long. There may be glands on the leaflets.
Axillary and fine-haired panicles , thyrses are formed at the branch ends. The small, hermaphrodite or only male, almost sessile to short stalked and five-fold flowers are white with a double flower envelope . The very small, almost free, triangular sepals up to 2 millimeters long are hairy on the outside. The narrow, egg-shaped to elongated, 3–4 millimeter long petals are somewhat fine-haired on the outside. The 10 short stamens are fused in the lower part in a tube, with the double-pointed, somewhat hairy, free and flat stamens on top. The anthers are attached inside, between the tips. The multi-chambered, mostly hairy ovary of hermaphrodite flowers is upper constant, the short stylus has a kopfige scar . There is one discus each.
Up to 1.5–3 centimeters in size, reddish and mostly single-seeded, ellipsoidal to rounded, slightly hairy, somewhat leathery berries are formed. The seeds have a whitish aril .
