Abutilon

Abutilon pictum

Abutilon (usually called Schönmalven ) refers to a genus of flowering plants of the mallow family ( Malvaceae ), which comprises about 200 species. Some species from numerous varieties were grown as ornamental plants.

Most of the species are native to South America and are evergreen. Some are located in the cooler mountain forests of Chile and are deciduous.

Description

Vegetative characteristics

Abutilon species are mostly woody plants: subshrubs, shrubs or small trees, of which the vast number is always green. The vegetative parts of the plant are hairy. The change-constant leaves are divided into petiole and leaf blade. The leaf blade is simple, rarely lobed (Abutilon pictum ) and pinnately with heart- shaped base. The leaf edges are serrated notched up. Stipules fall off early.

Generative features

The flowers are arranged singly or in pairs in the leaf axils or in few-flowered inflorescences. The hermaphroditic, flowers are radial symmetry fünfzählig. There is no by- cup available. The five green sepals are fused bell-shaped. The top five yellow to orange, rarely red ( often darker in the center ) petals are fused at the base and usually form a bell, rarely a tube ( Abutilon pictum ). Some of the species show with their flowers form an adaptation to pollination by hummingbirds. For them, the drooping flowers have an inflated calyx on a bell of five overlapping petals. In the subfamily Malvoideae the many stamens are fused into a tube surrounding the stamp, the so-called Columna. There are five to many carpels are fused to a five-to vielfächerigen ovary. The carpel are two to nine ovules available. There are five to pen many branches available.

The often blackish when ripe carpels are nearly spherical to hemispherical and decay usually in five to many partial fruits that have a leathery pericarp. The kidney-shaped seeds are glabrous or slightly hairy fluffy.
