Anopyxis klaineana is a tree in the rhizophore family from central to western Africa . It is the only species in the genus Anopyxis .
description
Anopyxis klaineana grows as an evergreen tree up to 40–50 meters high. The trunk diameter reaches up to 100-120 centimeters. Most of the time only small roots are formed, but only rarely smaller buttress roots . The brown-gray bark is slightly furrowed.
The simple, short-stalked, leathery and bare leaves are usually arranged in three to four whorls. The leaf stalk, which is flattened on the top, is 0.5–2 inches long. The leaves are entire and obovate to oblong, elliptical. They are about 6-13 inches long and 2.5-5.5 inches wide. At the top they are rounded to pointed or rounded. The linear to awl, somewhat hairy stipules are quite durable.
The flowers are arranged in more or less rusty hairy, short zymous groups, axillary or terminal. The green-whitish, hermaphrodite and short-stalked, small flowers are five-fold with a double flower envelope . The short, cup-shaped, greenish calyx is on the outside and in the middle, short, fine-haired, with 5 triangular to egg-shaped, expansive tips about 6 millimeters long. The fine and narrow petals, finely hairy in the upper part, up to 9 millimeters long, are spatula, spoon-shaped and short-pointed. The 10 stamens are fused tubular with the upright, almost sedentary anthers at the top. The dense beige hairy fünfkammerige ovary is upper constant, with relatively short, bare stylus with smaller capitate scar .
Egg-shaped, about 3–4 centimeters in size, five-lobed and fine, grayish hairy, septicidal, slightly ribbed capsule fruits with a permanent calyx are formed. They contain about 10 unilaterally winged, flattened, wedge-shaped and 8 millimeter large, red-brown seeds, the wing attached to a minimal stalk is up to 1.6-2 centimeters long and about 4 millimeters wide.
The number of chromosomes is 2n = 64.
Taxonomy
The first description of the Basionym Macarisia klaineana was in 1898 by Jean Baptiste Louis Pierre in Bull. Mens. Soc. Linn. Paris, ns, 1: 75. The division into the newly established genus Anopyxis took place in 1900 by Adolf Engler in HGAEngler & KAEPrantl, Nat. Plant family, Nachtr. 2: 49. Other synonyms are Pynaertia ealaensis De Wild. , Pynaertia occidentalis A. Chev. , Anopyxis ealaensis (De Wild.) Sprague and Anopyxis occidentalis (A.Chev.) A.Chev.
