In 1862, a tree was introduced to France, supposed to be a kind of Ailanthus. It has now been found to be of a different genus, and is Cedrala sinensis.

Quercus Andersoni, a new species of oak from the Sikkim Himalaya, was the subject of a paper by Dr. G. King at the last meeting of the Lin-nsean Society. It is the "Katoos" of the Nepau-lese, and one of the very finest of Indian forest trees. It is closely related to Q. spicata, but is met with at higher altitudes.
