Bryophyte flora of the Huon Peninsula, Papua New Guinea. LI : Additions and corrections to the Geocalycaceae (Hepaticae)

Abstract

This paper is part of a series dealing with the bryovermicularis (Lehm.) Grolle, which represents a flora of Papua New Guinea. Background informanorthward penetration of a southtemperate species, tion relating to the abbreviated presentation of the collecting localities and geographic ranges is present ed in the first and seventh parts of the series (KopoCLASMATOCOLEA VERMICULARIS (Lehm.) nen & Norris 1983, Norris & Koponen 1985). The Grolle (Fig. 1) published papers of the series are listed in Koponen et al. (1991); subsequent contributions are Enroth Rf B!y°1' LlTcheno1 fTM' ,'9ia -/TM8*rmannia vermi ,, _.. culartsLehm., Lmnaea4:361.1829.—Alicularia vermicularis (1991), Piippo (1991) and Bischler & Pnppo (1991).
