Menispermaceae
Menispermaceae (botanical Latin: 'moonseed family' from Greek ''mene'' 'crescent moon' and ''sperma'' 'seed') is a family of flowering plants. The alkaloid tubocurarine, a neuromuscular blocker and the active ingredient in the 'tube curare' form of the dart poison curare, is derived from the South American liana '' Chondrodendron tomentosum''. Several other South American genera belonging to the family have been used to prepare the 'pot' and 'calabash' forms of curare. The family contains 68 genera with some 440 species, which are distributed throughout low-lying tropical areas with some species present in temperate and arid regions. Description * Twining woody climbing plants, winding anti-clockwise ('' Stephania'' winds clockwise) or vines, rarely upright shrubs or small trees, more rarely still herbaceous plants or epiphytes (''Stephania cyanantha''), perennial or deciduous, with simple to uni-serrate hairs. * Alternate spiral leaves, simple, whole, dentate, lobed to palm ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
