hedereæ

Century Dictionary and Cyclopedia

1. That subdivision of the natural order of plants Araliaceæ to which the genus Hedera, the ivy, belongs: called by Bentham and Hooker (1862) a series, and embracing, besides Hedera, six other genera. The group is distinguished from the rest of the order by having the petals valvate and of the same number as the stamens, and the albumen of the seed wrinkled.
