The Torricelliaceae are a family of plants within the order of the umbelliferae (Apiales). The three genera with about ten species have a paleotropic distribution.

description

Vegetative characteristics

They are woody plants: they are shrubs or small trees .

The alternate and spirally arranged leaves on the branches have long stalks. The leaf can be divided in the shape of a hand or undivided. The leaf margins are smooth, serrated or serrated. Stipules are missing.

Generative characteristics

They can be mono or dioecious; the flowers can be unisexual or hermaphroditic. The inflorescences are structured very differently. The radial symmetry flowers are usually small and five-fold. There is only one circle with five stamens . Two to four carpels are a (syncarp) under constant ovary fused with two or three styli.

They form stone fruits .

Systematics and distribution

The two genera Aralidium (also as a separate family Aralidiaceae Philipson & Stone ) and Toricellia were earlier in the family of the Araliaceae Juss. classified; the genus Melanophylla became a separate family Melanophyllaceae Takht. ex Airy Shaw or earlier included in the Cornaceae family.

The Torricelliaceae ( Wangerin ) Hu family was founded in 1934 by Hu Xiansu in Bulletin of the Fan Memorial Institute of Biology: Botany. Volume 5, page 311 prepared. Type genus is Torricellia DC. The generic name Torricellia honors the Italian physicist and mathematician Evangelista Torricelli (1608–1647).

The Torricelliaceae family belongs to the order of Apiales .

The species of the family have their areas in the western Malay Archipelago , in Southeast Asia , in the eastern Himalayas , in western China and on Madagascar .

The Torricelliaceae family contains only three genera with about ten species:

• Aralidium Miq. : It contains only one type:
  • Aralidium pinnatifidum Miq. : It is dioecious separate sexes ( diocesan ) and is common from Malaysia to Indonesia . The number of chromosomes is 2n = 40.
• Melanophylla Baker : The leaves are mostly undivided. The inflorescences are mostly racemose . The flowers are hermaphroditic. The seven to eight species only occur in Madagascar :
  • Melanophylla alnifolia Baker (Syn .: Melanophylla capuronii Keraudren )
  • Melanophylla angustior McPherson & Rabenantoandro
  • Melanophylla aucubifolia Baker (Syn .: Melanophylla humbertiana Keraudren , Melanophylla humblotii Drake )
  • Melanophylla crenata Baker (Syn .: Melanophylla longipetala Keraudren )
  • Melanophylla madagascariensis Keraudren (Syn .: Melanophylla pachypoda Airy Shaw )
  • Melanophylla modestei G.E. Schatz , Lowry & A.-E. Wolf
  • Melanophylla perrieri Keraudren
• Torricellia DC. (Syn .: Toricellia DC. Orth. Var.): The leaves are undivided or divided into hands. They are single-sexed( monoecious ) or dioecious ( dioecious ). The inflorescences are profuse, drooping thyrses . The roughly two (to three) species occur in northeastern India only in Darjiling , Bhutan , Nepal , Sikkim and China:
  • Torricellia angulata Oliver (Syn .: Torricellia intermedia Harms , Torricellia angulata var. Intermedia (Harms ex Diels) Hu ): It occurs from southeastern Tibet to central China. The number of chromosomes is 2n = 24.
  • Torricellia tiliifolia DC. : It occurs from Nepal to western Yunnan . The number of chromosomes is 2n = 24.
