Meliosma simplicifolia

Credit: Shaukat

Shrubs or trees, rarely climbers. Leaves alternate, simple or imparipinnately compound, exstipulate. Inflorescence terminal or axillary, of few-flowered pedunculate cymes or panicles, rarely a simple raceme. Flowers bisexual or unisexual (plants then polygamo-dioecious), zygomorphic. Sepals (3-)4-5, free or basally connate, imbricate, persistent. Petals (3-)4-5(-6), mostly free, equal or unequal, antisepalous, imbricate. Stamens as many as petals, equal or unequal, antipetalous, all or only 2 larger fertile, the rest staminodial, anthers ovoid-globose, dithecous, with flattened connectives. Disc angular or cupular, dentate or lobed. Carpels 2-3, completely or slightly syncarpous; ovary superior, 2-3-locular, each locule with 2 semi-anatropous ovules on axile placentae; styles 2-3, free or united, stigma simple or 2-3-lobed. Fruit a subglobose drupe, 1-2-locular, 1-seeded, endocarp bony, exocarp fleshy, rarely dry and leathery. Seeds with or without endosperm.

A family of 3 genera and about 160 species; distributed from S.E. Asia to China and Japan and Mexico to Brazil in the new world. Represented in Pakistan by 2 genera, each having a single species.

This interesting family, showing probable connections with several diverse groups, was first established by Blume (Mus. Lugd. Bot. 1:368.1851) who placed it in the immediate neighbourhood of Menispermaceae indicating, at the same time, affinities with Lardizabalaceae. Hooker & Thomson (Fl.Ind. 1:206-207. 1855) believe it to be intermediate between Schizandraceae and Menispermaceae.

Airy Shaw (in Willis, Dict. Fl. Pl. & Ferns ed. 7.711.1966), following End¬licher, has split the family into Meliosmaceae consisting of Meliosma and Ophiocaryon and Sabiaceae with only Sabia.
