Bitterwood Tree
Picrasma
A genus of deciduous trees and shrubs known for their extremely bitter bark and medicinal …
Endemic to coastal and insular environments of East Asia, this deciduous woody taxon represents a rare variety of Biond's hackberry. It thrives in temperate forest zones, adapting well to sandy and rocky soils affected by maritime winds.
This variety plays a vital role in coastal forest ecosystems. It provides canopy cover and stabilizes soil in vulnerable island habitats.
This deciduous tree grows to moderate heights, featuring a greyish-brown bark and slender branchlets. The foliage consists of ovate to oblong-lanceolate leaves with serrated margins in the upper portion.
Its fruits are small, globose drupes that develop in the leaf axils, turning a distinct orange or reddish-orange color upon maturity in late summer or autumn.
Spring
Local ecosystems benefit from this tree as it serves as a windbreak in coastal and island areas. The wood, although less commercially significant, is tough and is occasionally used for minor agricultural tools or fuelwood.
Additionally, the small drupes are consumed by native avian species, assisting in seed dispersal across island landscapes.
This variety belongs to the complex species group of Celtis biondii, which is widely distributed across China, Japan, and the Korean Peninsula. Its adaptation to island conditions makes it a subject of interest for biogeographical studies.
