Mangifera caesia var. verticillata (C.B. Robinson) Mukherji

M. kemanga Blume is closely related to M. caesia, with which it is united by some botanists (e.g. in Flora Malesiana). It should, however, be considered as a species distinct from M. caesia. It can be recognized by its subsessile leaves with narrowly decurrent margins; its panicles which are longer (up to 75 cm long), more open and contain fewer flowers; its fruits which are dull yellow-brown at maturity, gibbous at the base and scurfy. Natural hybrids between M. kemanga and M. caesia, showing intermediate characteristics, are found in orchards in East Kalimantan.

M. kemanga are restricted to the wet tropical lowlands, generally below 400 m (rarely up to 800 m). It require a rainfall which is evenly distributed through the year. It also stand inundation well and are commonly cultivated on periodically inundated riverbanks in East Kalimantan. It is rather rare in forests and found more frequently in periodically inundated areas and marshes.

Kemang is commonly cultivated in western Java, especially near Bogor, but less frequently in Borneo where binjai dominates.

It is propagated from seed, an indication that the agronomy of the crops has received little attention. Presumably grafting on seedling stock would be possible, in particular through inarching potted, decapitated rootstocks into twigs of mother trees. Grafting on Mangifera indica L. has been attempted without success, probably because this species is not closely related.

Mature trees require much space, 12-16 m each way. No particulars about husbandry or yield levels have been published.

No particulars about pests and diseases have been published.

Food: Kemang fruit is eaten fresh when ripe, or used for home-made juice. It is used unripe to make 'rujak', a dish of sliced green fruit covered with a spicy sauce. Occasionally a dish is made from fresh, grated seeds, with fermented soya beans and spices. The Sundanese in western Java commonly eat the young leaves in 'lalab', a dish of fresh leafy vegetables.
