Blitum

Ähriger strawberry spinach ( Blitum capitatum )

Blitum is a plant genus of the subfamily Chenopodioideae in the family of Amaranthaceae ( Amaranthaceae ). It is closely related to the genus spinach. Some of their species were counted by 2012 to the goose feet ( Chenopodium ) and to the genus Monolepis.

Description

Blitum species are annual or perennial herbaceous plants without aromatic fragrance. Its surface is bare, sometimes covered by bubble hair and sticky young. The most numerous stems grow upright, ascending or spread out and are not or only slightly branched.

The alternate, simple, petiolate leaves form a rosette close to the ground often long- stalked leaves. The thin or slightly succulent leaf blade may be triangular, triangular - shaped pike, triangular - lanceolate or spatulate shaped leaf margin is smooth or serrated.

The flowers usually sit in compact, knäueligen partial inflorescences, which are arranged to sham- aged men inflorescences. Bracts are either missing or they are small and leaf-like. The hermaphrodite or purely female flowers possess ( a ) three to five herbaceous, ungekielte bracts, which are either fused together only at the base, or to about the middle. Occasionally, the perianth also missing. In hermaphrodite flowers, a circle with one to five stamens is present. The carpels are fused into a superior ovaries with two to four scars.

At the time the fruit perianth enclosing the fruit and is either fleshy or dry and hard. The membranous pericarp adheres to the seed coat. The vertically oriented seed is broad ovoid to spherical with dark brown or black seed coat.

Occurrence

The species of the genus Blitum come in Asia, Europe, North Africa, America and Australia (see disseminating information on the species list ).

System

The genus Blitum was erected in 1753 by Carl Linnaeus in Species Plantarum, Volume 2, page 4. The type species is Blitum capitatum L. Later, the species have long been asked to Chenopodium and regarded as a subgenus subgenus Chenopodium Blitum. After molecular genetic studies, they are rather related to Spinacia and do not belong to Chenopodium. Therefore, they were of Fuentes - Bazan et al. (2012 ) separated as a distinct genus Blitum and grouped together with Spinacia in the tribe Anserineae.
