Centrolepidaceae

Illustration of two Centrolepis species.

The Centrolepidaceae are a small family of plants that belongs to the order Süßgrasartigen ( Poales ). The types of Centrolepidaceae their areas in temperate to tropical regions in Southeast Asia, Australasia and South America.

Description

The types of Centrolepidaceae are small, grass - or moss-like, annual or perennial herbaceous plants; in annual species the leaves on the plant base ( basal ) are concentrated. The alternate and spirally on the stem arranged leaves are simple, sessile, parallel-veined and entire.

They are monoecious getrenntgeschlechtig ( monoecious ). The inflorescences are Pseudanthien in which many female and male flowers are grouped together, or there is all-male and all-female inflorescences; rarely the flowers are individually. The flowers are unisexual or rarely bisexual. Bracts absent. The male flowers contain only one fertiles stamen. In the female flowers one or many free, upper permanent carpels and the same number of pens are available. Pollination is by wind ( anemophily ).

Several small follicles are combined to form a capsule-like fruit collection. The tiny seeds contain starch.
