Abstract

For a clearer understanding of Riccardia obtusa S.W.Arnell, it is here described and illustrated in greater detail than in Arnell’s (1952) initial publication of his new species. Subsequently, with minor alterations. Arnell (1963) repeated his treatment of R. obtusa in Hepaticae of South Africa. Wigginton & Grolle (1996) have, however, remarked that this species needs to be clarified, along with the other two Amellian species of Riccardia, namely R. capensis and R. rhodesiae, which will betreated in detail in future papers.
