### Kalappia Kosterm.

Type species: K. celebica Kostermans.

Habit and leaf form. Trees; unarmed.

Phyllotaxy distichous. The leaves compound; pinnate; imparipinnate. The leaflets elliptic, few per leaf (about 3–7); alternate; symmetrical or nearly so; pinnately veined, with a predominant ‘midrib’. Stipules absent or early caducous or very inconspicuous in mature leaves; membranous. Stipels absent.

Inflorescence and floral morphology. The inflorescences axillary; branched; supposedly of cymose units; panicles. Bracts absent at anthesis (caducous). Bracteoles present; absent at anthesis.

The flowers hermaphrodite; not pentamerous throughout; departing from pentamery in the androecium. Hypanthium absent, the androecium hypogynous. The perianth comprising distinct calyx and corolla. Calyx 5; not Swartzieae type; polysepalous; more or less regular (the sepals subequal); members imbricate. Corolla present; slightly irregular (the ovate petals slightly unequal); 5; without greatly reduced members; polypetalous. Petals clawed, or clawed to sessile; imbricate; imbricate-ascending. Disk absent. The androecium comprising 7–9 members; members all free of one another; members markedly unequal; including staminodia. The staminodia 2–4; oppositipetalous. Fertile stamens 4–5 (oppositisepalous). Anthers attached at the base of the connective (shorter than filaments, and directed inwards at ninety degrees); dehiscing via pores or short slits. Ovary sessile or subsessile; free. Stigma not dilated (or only minutely so). Ovules few (3–5).

Fruit, seed and seedling. Fruit 1–3 seeded, a follicle; not drupaceous; winged longitudinally; narrowly, 1 winged (along only one suture); flat, the valves thin not becoming woody. Seeds flat, disk-like; with a straight or slightly oblique radicle.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, distributions of character states within any set of taxa, geographical distribution, and classification. See also Guidelines for using data taken from Web publications.
