Description

''Aphloia theiformis'' is an
evergreen In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, whic ...
shrub or small tree reaching up to high. Young branches are hairless, brown in colour, have stripes along their length and wings extending from the nodes, narrowing downwards and carries alternately set leaves in two rows. The blades of the leaves are elliptic in shape, long, wide, with a pointy or rounded tip, a (broad) wedge-shaped foot and a saw-toothed edge, particularly in from below midlength to the tip. There are some ten pairs of inconspicuous, papery and hairless side veins. The leaf stalks (or petioles) are long. The flowers are with one, two or three together in the axils of the leaves on up to long greenish stalks (or

When ripe, the ovary develops into a fleshy white berry of about in diameter with the stigma still present, that contains about ten roundish, slightly compressed seeds of 2½–3 mm (0.10–0.14 in).
