The dominant vegetation of the Cape Floristic Region is the fynbos which is typified by the presence of members of the Restionaceae (Cape reeds and grasses), the Proteaceae (Sugarbushes, pincushions and conebushes), Ericaceae (Cape heaths) and a number of other families, including the Asteraceae (Everlastings) and the Bruniaceae.
The Restionaceae is a family of evergreen, rush-like plants which is almost restricted to the southern hemisphere.
The African Restionaceae are relatively diverse in their seed dispersal mechanisms, which could be implicated in the survival of seeds during or after fires.

Restionaceae (Poales) are typical and often dominant elements in the "fynbos" vegetation of the Cape Floristic Region of Southern Africa and the kwongan vegetation of the South Western Floristic Province of Western Australia.
Fossil pollen records provided a minimum age of the common ancestor of Australian and African Restionaceae as 64ñ71 Mya, and this date was used to calibrate a molecular clock.
The substantial morphological and anatomical similarity between the African and Australian Restionaceae appear to preclude morphological innovations as possible explanations for the inter-continental differences.

In particular, Cutler, studying the anatomy of Restionaceae at Kew, noted numerous discrepancies between his findings and the existing classification(18) but was largely restrained from making taxonomic changes because the Australian members were under study by Johnson and Briggs.
In parallel with the morphological study of Restionaceae, DNA sequencing of representative species was begun, with expert advice from John Thomson and Peter Weston and assistance from Simon Gilmore, and later Adam Marchant and Carolyn Porter.

This group basically corresponds to the Order Restionales in Cronquist's (1981) classification, except that he placed the grasses in the Order Cyperales.
Since then it has generally been agreed that the Poaceae belong here, however, and in fact a few authors have removed the Restionaceae instead.
The Angiosperm Phylogeny Group's classification system includes several familes in order Poales that, in other classification systems, constitute separate orders (i.e.

Detailed anatomical investigations presented here show that the apparently similar gynoecia of some African and Australian Restionaceae are indeed the result of convergence.
In the latter case there is frequently a reduction to four tepals, paralleled by reduction in the gynoecium.
The gynoecial information by itself is not adequate to formulate a phylogenetic hypothesis for the Australian Restionaceae, but should provide valuable information for such a project.

It’s called Restionaceae, and looks like sedges or woody grasses, and the family only occurs in the Southern Hemisphere--in South Africa, in Australia, and (barely) in New Zealand.
So when I spent the fall (Southern Hemisphere spring) of 1974 in Western Australia, I decided I would learn the Restionaceae of Australia-then I would know this family.
In flower before me were male plants of a plant I knew had to belong to the family Restionaceae (bottom left and middle).

Abstract: Restionaceae are characterized by Polygonum-type development, a well-developed hypostase, the presence of starch grains in the mature female gametophyte, and a thick nucellus that is uniseriate at the micropylar end.
In general, proliferation of antipodals occurs in South African taxa of Restionaceae but not in Australasian taxa.
The presence of multiplied antipodals is the usual condition in the allied family Poaceae, but the sporadic occurrence of this character in Restionaceae cannot be used to support the view that the two families are sister groups.

 Digging Dog: The Color Encyclopedia of Ornamental Grasses by Rick Darke | Sedges, Rushes, Restios, Cat-tails, and ...
Gardeners usually speak of “ornamental grasses” in the broad sense, including not only the true grasses, but also related families of grasslike plants, such as sedges and rushes.
Following this tradition, this book provides a detailed treatment of the perennial grasses (Poaceae), sedges (Cyperaceae), rushes (Juncaceae), restios (Restionaceae), and cat-tails (Typhaceae) available to modern gardeners, as well as selected bamboos (Poaceae).
Ornamental grasses are a stunningly versatile group, offering myriad possibilities in the garden limited only by the imagination of the designer.
