description
Elaeocarpus angustifolius grows as a mostly semi-evergreen tree up to 35 meters or a little more. The trunk diameter reaches up to over 60–80 (up to 200) centimeters. Buttress roots are usually formed. The relatively smooth bark is brownish-gray and easily cracked with age.
The simple, short-stalked and almost bare leaves are alternate. The petiole is 1–2 inches long. The leaves are whole to serrated or notched at the edge, and are 6-18 centimeters long. They are egg-shaped, lanceolate to lanceolate or obscure-lanceolate and rounded to pointed. The "autumn color" is orange-red. The stipules fall off early.
Axillary, often unilaterally racemose and slightly hairy, small inflorescences are formed. The hermaphroditic, five-fold and white to cream-colored, pendulous, stalked flowers are double- coated . The rickety, eilanzettlichen and slightly hairy sepals are greenish to reddish mottled. The obverse-wedge-shaped, almost bare petals are fine, long-fringed. There are many (25–50) stamens with bristly anthers at the top. The above constant, multilocular ovary is hairy with a bare conical stylus . There is a hairy disc .
Roundish and blue, about 15-24 millimeters large, bald drupes are formed. The multi-seeded (2–5), bony stone core is pitted, more or less sculpted and hard.
Taxonomy
