Combretocarpus rotundatus is a tree in the Anisophylleaceae family from Borneo , Sumatra, and southern Malaya . It is the only species in the Combretocarpus genus.
description
Combretocarpus rotundatus grows as an evergreen tree around 25–40 meters high. The trunk diameter reaches 80-100 centimeters. The gray to brown bark is cracked and there may be smaller board or, more rarely, stilt roots and pneumatophores .
The simple, short-stalked and alternate, leathery leaves are ovate to elliptical, rounded or obovate. The petiole is about 8-15 millimeters long. They are about 6-13 centimeters long and with entire margins and rounded to rounded at the tip. The stipules are missing. The young leaves are reddish.
There are axillary and traubig- panicles formed short inflorescences. The small, hermaphrodite and stalked, yellow flowers are usually threefold with mostly double inflorescence , the petals can also be missing. The outside scaly calyx is cup-shaped with lobed and recessed, egg-shaped, somewhat ciliate lobes and the short to minimal petals are mostly fringed or lobed to elongated, ribbon-shaped. There are 6–8 stamens with filamentous stamens. The multi-chambered ovary is subordinate with three awl styles with threadlike scars . There is a lobed disc .
Usually three-winged and single-seeded wing nuts (Samara) are formed. They are about 1.5-2 centimeters long and 2-3 centimeters wide with the paper-like wings.
Taxonomy
The first description of Basionyms Macro Solen rotundatus was in 1860 (Publ. 1861) by Friedrich Anton Wilhelm Miquel in Flora van Nederlandsch Indie, Eerste Bijvoegsel, Suppl. 346. The reallocation in the 1865 by Joseph Dalton Hooker in G.Bentham & JDHooker, Gen. Pl. 1: 683 established genus Combretocarpus to Combretocarpus rotundatus was made in 1929 by Benedictus Hubertus Danser in Bull. Jard. Bot. Buitenzorg, sér. 3, 10: 345. A synonym is Combretocarpus motleyi Hook.f.
use
The rather heavy, moderately resistant wood is known as perepat danat or keruntum . The wood is not to be confused with that of Sonneratia alba, which is also called Perepat.
