    A systematic study of the genus Pseudopentameris (Arundinoideae: Poaceae)
    (1995) Barker, N P
    The genus Pseudopentameris Conert is examined morphologically and anatomically. A phenetic study of the morphologica ly  variable species  P. macrantha indicates that two taxa should be recognised. One of these.  P. caespitosa N.P. Barker, is described as new. In addition, the study supports the inclusion of  Pentameris obtusifolia in  Pseudopentameris. The genus Pseudopentameris is re-delimited to accommodate the new taxa, and a key to species is provided. Details of the cytology, phylogeny and conservation status of taxa in the genus are also discussed.

    External fruit morphology of southern African Arundineae (Arundinoideae: Poaceae)
    (1994) Barker, N P
    Fruits of a number of taxa of all indigenous southern African arundinoid genera were examined by means of SEM. Size, shape, compression, surface sculpturing, embryo anti hilum features were recorded and fruits of all genera are illustrated. Results are compared to existing descriptions. The genera are placed in five informal groups according to similarities noted in the fruits.
