Sutera is a genus within the family of figworts in the order of Lippenblütlerartigen ( Lamiales ).

Description

Sutera grow independently upright to creeping or hanging as annual to perennial herbaceous plants or subshrubs to small shrubs. Some species are aromatic scented. The hairy parts of plants may be glandular or smooth. The opposite or nearly opposite constantly arranged leaves are petiolate to sessile with serrated, wavy to lobed, rarely smooth margin.

The flowers are individually together in the leaf axils or in terminal, racemose, or aged men zymösen inflorescences on Blütenstandsschäften. The bracts are deciduous leaves similar but smaller. The hermaphrodite flowers are zygomorphic and fünfzählig double perianth. The five sepals are fused and double lip. The five petals are fused Roehrig, the corolla tube may be longer or shorter than the calyx. The five Kronlappen are rarely short of two parts. There are only four stamens present, which sometimes extend beyond the corolla tube, the corolla tube. The thread-like stamens arise in the corolla tube. The ovary is zweifächerig. The thin stylus does not project beyond the corolla tube. The scar is very short and slightly bifurcated.

The septizide capsule fruit is zweiklappig and contains many seeds. The small, gray-blue or ocher-colored seeds have a textured surface.

Dissemination

The genus Sutera was first published in 1807 by Albrecht Wilhelm Roth Botanical comments and corrections, p 172.

Previously, the genus containing about 130 species. However, it was not monophyletic, but their two subgenera Sutera and Chaenostoma proved to be monophyletic, the subgenera to genera with the reactivation of the genus Chaenostoma Benth. Were, some species are now in the genus Jamesbrittenia Kuntze.

Formerly included the ornamental plant Bacopa ( Chaenostoma cordatum, Syn: Sutera cordata, Sutera diffusus ) to this genus, whose white varieties are referred to as " The Snow Maiden " in the plant trade.
