Description

Appearance and leaves

Wendlandia species are evergreen, woody plants that grow as shrubs or small trees. They are unarmed. The branches are sometimes somewhat flattened.

The mostly opposite or rarely in threes arranged in whorls leaves are divided into petiole and leaf blade. The leaf stalks can sometimes be very short, then the leaves are almost sessile. They usually do not have Domatien. The base of the petioles is divided. The simple leaf blades are usually ovate or oblong. The leaf margins are often serrated and the venation is often not visible on the underside of leaves. The durable up early falling as a whole or by fragmentation stipules are triangular or deciduous leaf-like, upright and flat to folded lengthwise or spread to back with all your curved or sometimes two-piece top.

Inflorescences and flowers

The terminal, zymösen, thyrsoiden or schirmrispigen inflorescences usually contain many flowers. There may be Blütenstandsschäfte. In a two to three inflorescence bracts are present. There may be a flower stems. Usually the flowers of a copy or even a population appear simultaneously open.

The strong in some species, with most something fragrant hermaphrodite flowers are zygomorphic and rarely four, usually fünfzählig double perianth. The lasting flowers cup ( hypanthium ) is relatively small and almost spherical. The rarely four, usually five nearly equal sepals are fused and the Goblet ends with four or five recognizable, oblong- obtuse calyx teeth. The petals are often white, whitish to yellow or red, pink to purple. The rarely four, usually five petals are tubes, funnel, stem plate or short bell-shaped overgrown. The corolla tube is inside glabrous or pubescent and often recurved at anthesis at the top. The rarely four, usually five corolla lobes are imbricate overlapping in the flower bud and during anthesis strongly recurved to be rolled down. There are rarely four, usually five stamens present; they are about the same length as the crown or they project beyond these. The short-to well-developed stamens are inserted near the mouth of the crown. The two - or rarely insulated draft tube ovary contains many ovules on a shield-shaped or small spherical placenta. The thin stylus usually ends in a club-shaped, two columns or two-piece scar that rises above the crown ( at Wendlandia pendula the scar is incised ).

Fruit and seeds

The more or less spherical capsule fruits are surrounded by tough sepals and contain many seeds. The parchment-like or woody, usually two, rarely dreifächerigen fruit capsules open lokulizid mostly on the upper portion with two flaps fruit and rarely split septizid thereafter. The relatively small seeds are flattened horizontally with membranous, net-like grooved seed coat ( testa) and fleshy endosperm. The seeds sometimes have narrow, barely discernible wings.

Sets of chromosomes

The basic chromosome number is in the few species studied mostly x = 11, it is diploidy ago, so 2n = 22 In Wendlandia notoniana basic chromosome number is x = 12

Systematics and distribution

The genus Wendlandia in 1830 by Friedrich Gottlieb Bartling in Augustin- de Candolle Pyrame: placed Prodromus systematis Naturalis Regni Vegetabilis, Volume 4, pp. 411.
