FAMILIA SCHISANDRACEAE PDF

See Article History Schisandraceae, family of three genera and some 90 species of flowering plants of the primitive order Austrobaileyales. The family consists of mostly tropical and subtropical woody plants. All have radially symmetrical, mainly beetle-pollinated flowers that lack differentiation between the outer and inner floral whorls sepals and petals. The family is botanically significant in having features showing characteristics of ancient gymnosperm groups, such as wood with primitive vessels water-conducting cells. Brian Arthur The genera Schisandra, with about 25 species, and Kadsura, with 22 species, are mostly climbing vines with separate male and female flowers that are often found on separate plants.

The family is botanically significant in having features showing characteristics of ancient gymnosperm groups, such as wood with primitive vessels water-conducting cells. Brian Arthur The genera Schisandra, with about 25 species, and Kadsura, with 22 species, are mostly climbing vines with separate male and female flowers that are often found on separate plants.

The fruits produce one to five seeds each. A few species are occasionally cultivated as ornamentals—for example, the magnolia vine, or five-flavour berry Schisandra chinensis , for its fragrant white or pink flowers and attractive fruits, and kadsura vine Kadsura japonica , for its clusters of scarlet-coloured fruits. The genus Illicium, with 42 species, was formerly placed in the now-defunct family Illiciaceae.

It consists of shrubs and trees having evergreen, aromatic leaves and bisexual flowers, the inner petals of which grade gradually into stamens male pollen-producing structures. The female portion of the flower consists of 7 to 15 carpels ovule-bearing structures , usually in a single whorl. At maturity the flower produces a characteristic woody fruit composed of a ring of several joined podlike follicles, each of which splits open along one seam to release a single seed.

The star anise Illicium verum , named for this characteristic fruit, is a shrub, the dried fruits of which are the source of oil of star anise, a volatile, aromatic oil used for flavouring candies, liqueurs, and perfumes. Learn More in these related Britannica articles:.

The Families of Angiosperms

Pollination[ edit ] Schisandaceae are pollinated predominantly by nocturnal gall midges that lay their eggs in the male and female flowers in Schisandraceae species with unisexual flowers or the male-stage and female-stage flowers in species with bisexual flowers. The larvae of these midges develop in the floral tissue once it has dropped to the ground, feeding on floral exudates not ovules or pollen. Botanical Journal of the Linnean Society.
