Description

Vegetative characteristics

Maesa species grow as an evergreen, woody plants: mostly shrubs, rarely small trees or vines. Spikes are never present. In the leaves, sepals and petals Sekretionsgänge are well developed.

The alternate and spirally arranged or distichous on the branches of deciduous leaves are simple and stalked. The leaf margins are smooth, toothed or serrated. The Blattnervatur is even recognized by dried leaves usually little. Stipules absent.

Generative features

They are usually axillary, simple or branched, racemose or eared inflorescences with small bracts. Directly above two cover sheets sit the flowers. The five petals are usually unisexual or hermaphrodite and have a double perianth. If the flowers are unisexual, the plants are monoecious getrenntgeschlechtig ( monoecious ). The five sepals are fused funnel-shaped and with the ovary and the calyx is also available on the fruit. The five white or yellowish petals are fused bell-shaped. It's just a circle with five free stamens with short stamens present. Two to five carpels are a syncarp, usually under permanent or semi- inferior ovary adherent to apotropen ovules. Nectaries are located on the ovary. The stamp is longer than the stamens, with a capitate or three-to five-lobed stigma.

Are formed stone fruits or berries; they are surrounded by the calyx. The berries contain many small, angular seeds.

The chromosome rates are n = 10

Systematics and distribution

They are widely used in the Paläotropis. Areas are located for example in Africa, the Indian subcontinent with China ( 29 species ) and Southeast Asia to Japan, on the Malay Archipelago and northeastern Australia.

Botanical history

After APG III, the family of Primulaceae has been substantially expanded and some families that the earlier in the order of Primulales Lindl. summarized were classified as subfamilies. The genus Maesa formed last own family Maesaceae and today the subfamily. For some authors, the genus Maesa was classified into the family of Myrsinaceae. The Tribe Maeseae in 1834 by Alphonse Louis Pierre de Candolle in Pyrame Trans Linn. Soc. London, 17, 132 first published. The first publication of the subfamily was performed in 1844 by Alphonse Louis Pierre de Candolle in Pyrame Prodr. , 8, 76 The Maesaceae family was only in 2000 by Arne Anderberg, Bertil Ståhl & Mari Källersjö in Maesaceae, a new family in the order Ericales primuloid sl in Taxon, 49, pp. 183-187 situated. The botanist Pehr Forsskål was first aware of the type species of Maesa lanceolata, as he traveled through the present-day Yemen, described in 1775 in Flora Aegyptiaco Arabica, pp. 66 and thus erstveröffenlichte the generic name Maesa. Synonyms for Maesa Forssk. are: Baeobotrys J.R.Forst. & G.Forst. and Doraena Thunb ..
