The Centrolepidaceae are a small family of plants belonging to the order of the sweet grass-like (Poales). The species of the Centrolepidaceae have their areas in temperate to tropical areas in Southeast Asia , Australasia and South America .
description
The species of the Centrolepidaceae are small, grass or moss-like, annual or perennial herbaceous plants ; in annual species the leaves are concentrated at the base of the plant (basal). The alternate and spirally arranged leaves on the stem are simple, sessile, parallel-veined and with entire margins.
They are single sexed ( monoecious ). The inflorescences are pseudanthia , in which many female and male flowers are combined, or there are purely male and purely female inflorescences; the flowers are rarely solitary. The flowers are unisexual or rarely hermaphroditic. Bracts are missing. The male flowers contain only one fertile stamen . The female flowers have one or many free, upper carpels and an equal number of styles. Pollination takes place by the wind ( anemophilia ).
Several small follicles are grouped into a capsule-like collective fruit. The tiny seeds contain starch .
Systematics
The Centrolepidaceae family was established by Stephan Ladislaus Endlicher . The species of the Hanguanaceae family were spun off in 1975 so that the Centrolepidaceae family is monophyletic .
There are only about three (to five) genera with about eleven to 40 species in the Centrolepidaceae family:
-
Aphelia
R.Br. ( Syn . : Brizula Hieron. ). Note: In zoology, Aphelia Huebner 1825 is a genus of the tortrices (Tortricidae). The approximately six plant species are distributed from southwest to southeast Australia , including Tasmania:
- Aphelia brizula F. Muell.
- Aphelia cyperoides R.Br.
- Aphelia drummondii (Hieron.) Benth. (Syn .: Brizula drummondii Hieron. )
- Aphelia gracilis Sond. (Syn .: Brizula gracilis (Sond.) Hieron. )
- Aphelia nutans Benth. (Syn .: Brizula nutans (Benth.) AWHill )
- Aphelia pumilio F. Muell. ex Sond.
- Centrolepis Labill. (Syn .: Alepyrum Hieron. , Alepyrum R.Br. , Devauxia R.Br. nom. Superfl., Pseudalepyrum Dandy ): The approximately 25 species are from the southern Chinese province of Hainan (a species) via Cambodia , Vietnam , Thailand , Indonesia , Malaysia , the Philippines , Papua New Guinea , Australia, New Zealand up to the Pacific Islands.
-
Gaimardia Gaudich. : There are about four species in a disjoint area in the southern hemisphere:
- Gaimardia amblyphylla W.M.Curtis : She comes to Tasmania before.
- Gaimardia australis Gaud. : It is the only species of family found in southern (Antarctic) South America in the Magellan region and the Falkland Islands .
- Gaimardia fitzgeraldii F. Muell. & Rodw. : It occurs only in western Tasmania .
- Gaimardia setacea Hook. f. : It occurs on Mt. Wichmann in New Guinea, in Tasmania on New Zealand's South Island.
