The giant windowpane palm (Beccariophoenix madagascariensis) belongs to Aracaceae (the Palm family). It is a semi-tall evergreen tree that is native to Madagascar. This tree grows in tropical rainforest, and up to a height of 10 m. It is robust, solitary and the trunk is erect. The leaves are fan-shaped, can be 4.5 m long, and crowded atop of the trunk. The male flowers relatively very large, covered with white wax. The female flowers only slightly larger than the male. The fruit is relatively large about 1 cm long, ovate with a short triangular beak, purplish in color, covered in thin wax. The sap is tapped from the trunk to make a sweet drink that is consumed locally. Young leaves of the plant were used for making a special hat known as "Manarano". Their excessive exploitation greatly reduced population levels of this species, almost extincting it.
