Abeliophyllum distichum ( English : White Forsythia ), also known as snow forsythia in German , is the only type of Abeliophyllum , a monotypical plant genus in the olive family (Oleaceae). This endemic species of the Korean Peninsula is endangered in some natural locations. In the past, many ofthese habitats were destroyed by their admirers. The generic name probably honors the English doctor and botanist Clarke Abel (1789 - 1826). According to Lee and Park (1982), the species isclosely relatedto Fontanesia , but based on the ITS sequences it is more likely to belong to the forsythia (K. Kim 1998).
description
Abeliophyllum distichum is a deciduous shrub with square trunks and reaches heights of 1 meter or more. The opposite arranged leaves are divided into a petiole and a leaf blade. The petiole is 5 to 6 mm long. The simple leaf blade is 6 to 10 cm long and 3 to 4.5 cm wide and lanceolate to ovate-elongated. Both the top and bottom of the leaf are hairy.
The flowering time is in the spring before the first new leaves appear. The lateral, racemose inflorescences have a dark purple inflorescence axis ( Rhachis ). The fragrant flowers are four-fold. The four white or pale pink petals are about 1 cm long. The wing nut , which is 2 to 3 cm in diameter, contains one seed per seed pocket.
The number of chromosomes is 2n = 28.
distribution and habitat
Abeliophyllum distichum occurs only at seven localities in central South Korea , one occurrence in North Korea is unconfirmed. Abeliophyllum distichum is disjointly distributed, each subpopulation consists of 40 to 200 individuals.
It occurs in rocky areas with dry surfaces and moist subsoils, often under Japanese red pine , myrtle-leaved oak or Japanese chestnut oak .
use
Abeliophyllum distichum is widely grown as an ornamental plant because of its white, fragrant flowers .
