Aucuba is a genus of three to ten species of flowering plants, now placed in the family Garryaceae, although formerly classified in the Aucubaceae or Cornaceae.

Contents

Aucuba species are native to eastern Asia, from the eastern Himalayas east to China, Korea, and Japan. [1] The name is a latinization of Japanese Aokiba. [2] They are evergreen shrubs or small trees 2–13 m tall, similar in appearance to the laurels of the genus Laurus , having glossy, leathery leaves, and are among the shrubs that are mistakenly called laurels in gardens. [3]

The leaves are opposite, broad lanceolate, 8–25 cm long and 2–7 cm broad, with a few large teeth on the margin near the apex of the leaf. Aucubas are dioecious, having separate male and female plants. Flowers are small, 4–8 mm diameter, each with four purplish-brown petals; 10-30 are in loose cymes. Fruit are red drupes about 1 cm in diameter. [4]

Species with leaves of variegated color

Three species (A. chinensis, A. himalaica, A. japonica) have traditionally been accepted, but more recently Flora of China [4] and Plants of the World Online [1] accept ten species:

  1. Aucuba albopunctifolia Southern China. Shrub to 2–6 m tall.
  2. Aucuba chinensis – Southern China, Taiwan, Myanmar, northern Vietnam. Shrub to 3–6 m tall.

<span class="mw-page-title-main">Privet</span> Genus of flowering plants in the family Oleaceae

A privet is a flowering plant in the genus Ligustrum. The genus contains about 50 species of erect, deciduous or evergreen shrubs, sometimes forming small or medium-sized trees, native to Europe, north Africa, Asia, many introduced and naturalised in Australasia, where only one species, Ligustrum australianum, extends as a native into Queensland. Some species have become widely naturalized or invasive where introduced. Privet was originally the name for the European semi-evergreen shrub Ligustrum vulgare, and later also for the more reliably evergreen Ligustrum ovalifolium and its hybrid Ligustrum × ibolium used extensively for privacy hedging, though now the name is applied to all members of the genus. The generic name was applied by Pliny the Elder to L. vulgare. It is often suggested that the name privet is related to private, but the OED states that there is no evidence to support this.
