Lemma Micromorphology and the Systematics of Siberian species of Stipa
26 June 2015
Olonova, Marina; Barkworth, Mary; Gudkova, PolinaWe investigated the lemma micromorphology of 17, primarily Siberian, species of Stipa using scanning electron microscopy. All the species had variants of the micromorphology considered typical for Stipa but each had a unique combination of characteristics, enabling its identification to species solely on the basis of its lemma micromorphology. Phenetic analysis revealed little correlation between the observed variation and the current sectional treatment of the species. The data support exclusion of Stipa borysthenica from Stipa pennata. A key to the species is provided.
