Description


Dais glaucescens takes the form of a shrub or small tree, growing up to 8 metres (8.7 yd) tall. The trunk can be up to 25 centimetres (9.8 in) in diameter.[4]


Distribution and habitat


Dais glaucescens is native to the central areas of Madagascar. It is found in forests, usually near water, at elevations of roughly 1,000 metres (1,100 yd).[4]


Uses


In Madagascar, the bark of Dais glaucescens is known as "havoa" and is used in the making of Antemoro paper.[5] This practice of using the "beaten-bark technique" has been attributed to the Antemoro people as far back as 1661 by the French governor of Madagascar Étienne de Flacourt.[6]
