Restionaceae

The delimitation of the family as it is now generally accepted has been liable to changes. Moreover, representatives of other families have occasionally been confused with Restionaceae. In habit Restionaceae are very like Cyperaceae, specially Rhynchosporoideae, and grow in similar habitats. They can be distinguished from the latter by open leaf-sheaths, the pendent, apically inserted ovules, and the absence of peculiar ‘cone-cells’ in the epidermis (‘Kegel-Zellen’, cf. KÜKENTHAL in Fedde, Rep. 53, 1944, 89).
