- Abstract
An isolectotype specimen of Eustichia africana deposited in the herbarium LW (Lviv, Ukraine) is discussed and illustrated here. The LW isolectotype of Eustichia africana is found to be the most complete (largest in terms of the number of plant fragments) original collection among initial syntypes (now the lectotype at PRE and numerous isolectotypes) of this taxon distributed in Rehmann's exsiccatae (and kept in W, PC, PRE, etc). A detailed description and illustration of the LW isolectotype specimen are provided. The special investigation of LW specimens of Fissidens eustichium found to confirm species status of Eustichia africana, which is different from E. longirostris (Brid.) Brid. to which sometimes E. africana was included as synonym since 1923 (while Fissidens eustichium Rehmann nom. nud. was included as synonym [to the latter taxon (= E. longirostris)] since 1894). Thus, the name and the accepted status of species Eustichia africana are resurrected.
