Exormotheca bulbigena sp. nov. (Hepaticae, Marchantiales) and its relation to E. holstii in southern Africa

Abstract

A new species Exormotheca bulbigena is described from southern Africa and its relation to E. hostii Steph, is discussed. Morphologically these species are very similar and can be distinguished only when fertile. The chromosome numbers, however, n = 32 for E. bulbigena and n = 18 for E, holstii, distinguish sterile living plants.
