Cryptocarya agathophylla (known in Madagascar as ravintsara and sometimes called clove nutmeg) is a member of the laurel family, Lauraceae, and originates in Madagascar.
Malagasy names include tavolobelelo,[1] havozo, hazomanitra and tavolomanitra. The former genus name Ravensara is a latinization of the Malagasy word ravintsara.[3]
Description
[edit]Cryptocarya agathophylla is a small to medium-sized tree, growing up to 15 meters high.[1] The leaves and twigs of C. agathophylla have a mildly camphorous aroma similar to eucalyptus.
Range and habitat
[edit]Cryptocarya agathophylla is endemic to Madagascar. It grows in humid and subhumid lowland forests and lower montane forests and secondary vegetation between 10 and 1,300 meters elevation.[1]
It is known from 11 locations in the central and eastern parts of Bongolava, Vatovavy Analanjirofo and Alaotra-Mangoro regions. Its estimated extent of occurrence (EOO) is 116,739 km2, the minimum area of occupancy (AOO) is 56 km2.[1]
Conservation and threats
[edit]The species' population is decreasing, and its conservation status is Near Threatened. It is threatened by habitat loss, principally from shifting agriculture, and also from logging, mining, and grazing.[1]
Essential oil
[edit]The essential oil of C. agathophylla is used as a fragrance material in the perfumery industry, and as an antiseptic, anti-viral, antibacterial, expectorant, anti-infective in natural and folk medicine.[4] Primary aromatic components are:[citation needed]
