Restionaceae
Alternative names: Not Applicable
Description:
Rush-like perennials; leaves reduced to brown sheathing bracts, imbricate at the base of and distant along the stem, split on one side and not tubular (unlike Cyperaceae).
Flowers unisexual and mostly dioecious, or rarely bisexual, arranged in spikelets or panicles, rarely solitary, each flower in the axil of a rigid glume; perianth of 6 or fewer scale-like segments, rarely 0; male flowers usually with 3 stamens opposite the inner perianth-segments; anthers 1-celled, oblong and dorsifixed (in S.Aust. genera), introrse by longitudinal slits, a rudimentary ovary occasionally present in the centre of the flower; female flowers with a 1-3-celled ovary, and 1-3 slender styles or branches; staminodes present in some species; ovule I in each cell, pendulous, orthotropous.
Fruit a capsule or nut; seed albuminous.
Distribution:
|
30 genera and more than 250 species almost limited to South Africa, Australia and New Zealand. (Evans & Johnson (1966) Contr. N.S.W. natn. Herb., Fl. ser. no. 25).
