Distribution
A small genus of five species from Australia, New Caledonia to Malesia; two species are recorded from New Guinea: Deplanchea glabra Steenis and D. tetraphylla (R.Br.) F.Muell.
Morphology General Habit
Trees 1.5–25 m tall, stems thick with pithy branches
Morphology Leaves
Leaves simple, in whorls of 3–4, at the end of the branches, margins entire; not drying black
Morphology Reproductive morphology Inflorescences
Inflorescence terminal, few flowered thyrses; calyx campanulate, 5-lobed, tearing into 2–5 irregular lobes unequal in size; corolla yellow, tubular to campanulate, 5-lobed, imbricate in bud, lobes ciliate; stamens 4, didynamous, exserted, 5 staminodes rarely present, inserted above the base of tube
Morphology Reproductive morphology Fruits
Fruit ellipsoid, a flat follicle with very hard, glabrous, boat-shaped valves, septum flattened, lens shaped, thick
Morphology Reproductive morphology Seeds
Seeds roundish with a very thin hyaline wing all around.
Ecology
Common in dry areas and open grasslands and gallery forest, very rare in rain forest, between 0–700(–1200) m.
Recognition
Deplanchea can be recognised by the simple leaves which are placed in whorls at the tip of the branches, which is unusual for the family because most genera have compound leaves; the flowers have conspicuous yellow corollas.
