Cultivar 'Boissieri'
Origin Iran

The Field Elm cultivar Ulmus minor 'Boissieri' Grudz., (Persian: نارون برگ‌ریز or نارون گل‌پشه‌ای), found in Iran and identified by Irina Grudzinskaya as the species U. boissieri in 1977.[1][2] The tree is endemic to the Zagros forests, with Quercus brantii, Celtis australis, Platanus orientalis, Fraxinus sp., and Cerasus mehaleb.[3][4] The tree is also found in the provinces of Kermanshah (Qasr-e Shirin, Bisotun) and Kerman.[5]

Richens however, treated U. boissieri as Ulmus minor.[6]

By the proposed rule that known or suspected clones of U. minor, once cultivated and named, should be treated as cultivars, the tree would be designated U. minor 'Boissieri'.[7]

Description

'Boissieri' is easily distinguished by its small leaves and fruits. The ovate, toothed leaves are 1.5 – 3 cm long, 1.2 – 2 cm broad, typically asymmetric at the base, the upper surfaces glabrous. The leaf veins number from 8 to 12; the petiole 2 – 3 mm long. The perfect apetalous wind-pollinated flowers are minute; the suborbiculate samarae 7 – 9 mm in diameter, with the seed located in the centre.

Pests and diseases

Not known.

Cultivation
