AUSTRAL HEPATICAE 34. THE SPOROPHYTE OF NEOGROLLEA HODGS. AND THE TAXONOMIC POSITION OF NEOGROLLEACEAE (SCHUST.) ENGEL & BRAGGINS COMB. & STAT. NOV.

抄録

  Current classification of the New Zealand hepatic Neogrollea notabilis Hodgs. in Lepidoziaceae and in Suborder Lepidoziineae is discussed. Recent discovery of the gynoecium and sporophyte, together with detailed morphological studies of the gametophyte, show that Neogrollea is beyond the circumscription of the Lepidoziaceae. The genus is therefore placed in a new family, Neogrolleaceae. The new family possesses a number of characters that will exclude it from Suborder Lepidoziineae, and a new suborder, Subord. Neogrollineae, is created for it. Placement of the Neogrollineae as the basalmost perianth-bearing member of Jungermanniales is discussed and proposed.
