Utania

See text Utania is a genus of flowering plants belonging to the gentian family (Gentianaceae), the tribe Potalieae, and the subtribe Potaliinae.

Small to medium trees, usually 1-3m tall, but occasionally up to 30m.

Features that distinguish this genus from other Gentianaceae include an architecture with continuous stem or trunk growth; branches that grow plagiotropic (inclined away from the vertical, inclined towards the horizontal) with a leaf arrangement that is distichous ("two rowed", where leaves are arranged in two vertical columns on opposite sides of the stem); non-resinous terminal vegetative buds; and an inflorescence that is pendulous and has a structure that is an elongate panicle with branching that is cymose (several pairs of branching, condensed, distinctly shorter than rachis), white flowers; the dried fruit (pale to dark brown at maturity) have a surface that is firm and smooth, with the epidermis not detaching from the pericarp.

[3][4] Shared with some other genera, Utania has fruit that do not produce any latex and polygonal seeds.
