Distribution

Asia-Tropical: Borneo present; Malaya (Peninsular Malaysia present); Philippines (Philippines present); Sumatera (Sumatera present), Palawan present, W. Java present
Malesia: Sumatra, Malay Peninsula, W. Java, Borneo, Philippines (Palawan: MERRILL 806, sterile). .

Uses

The roots and fruits are known as poisonous; leaves and stems have medicinal properties.
According to HEYNE the branches are resistant to humidity and therefore used as binding material under water.

Notes

Most records from the Philippines concern the related A. crassa.
Juvenile forms are often found creeping on open places, on tree trunks and rocks, and are provided with typical lobed or lunate leaves with more or less peltate blade-base; A. vespertilio is a juvenile from with lunate leaves.
Occasionally 4-merous ♂ flowers are found; once a ♀ flower with a 4-carpellate pistil; once a ♀ flower with 8 staminodes. A. quadrifida is based on a specimen in which part of the flowers have 4 calyx lobes.
Modecca cordifolia and M. obtusa date both from 1826. M. obtusa was listed first in the synonymy of A. cordifolia by KOORDERS, 1912.
Often galled flowers or slightly deformed flowers with an insect larva within are found.
