Description

The tree was said to have particularly deep-green leaves.

Cultivation

A possible specimen survives at Wakehurst Place in England, where it is kept cut low as part of a hedge to spare it the attentions of the bark beetles which act as vectors of Dutch elm disease. The tree is not known to have been introduced to North America or Australasia, nor is it known to be in commerce.
