Leaf anatomy of the South African Danthonieae (Poaceae). XIV. <i>Pentameris dregeana</i>

Leaf anatomy of the South African Danthonieae (Poaceae). XIV. <i>Pentameris dregeana</i>

Transverse sections and abaxial epidermal scrapes of leaf blades of Pentameris dregeana Stapf, both of herbarium specimens and of freshly fixed material, were examined by light microscopy. The anatomical structure was found to be basically uniform in a representative sample. A few somewhat atypical...

XIV. <i>Pentameris dregeana</i>R. P. Ellis0Botanical Research Institute.

The anatomical structure was found to be basically uniform in a representative sample. A few somewhat atypical specimens, how'ever, showed epidermal similarities with  Pentaschistis colorata (Steud.)
