Description

Schizolaena exinvolucrata grows as a tree up to 15 metres (50 ft) tall. Its leaves measure up to 8 cm (3 in) long. The peduncle and sepals are glabrous. It has a fleshy, glabrous involucre.[3] The involucre is thought to attract lemurs, bats and birds who in turn disperse the tree's seeds.[1]

Distribution and habitat

Schizolaena exinvolucrata is known only from the eastern regions of Atsimo-Atsinanana, Vatovavy-Fitovinany, Alaotra-Mangoro, Analanjirofo, Atsinanana and Anosy. Its habitat is humid and subhumid forests from sea-level to 1,000 m (3,300 ft) altitude.[2]

Threats

Schizolaena exinvolucrata is threatened by deforestation due to shifting patterns of agriculture. Four of the tree's subpopulations (of 13) are within protected areas.[1]
