A synopsis of the New Zealand species of Schistidium (Grimmiaceae; Musci), with observations on a little known species of Racomitrium

Abstract

A synopsis of the New Zealand representatives of Schistidium is presented, treating S. apocarpum, S. rivulare var. rivulare, and S. rivulare var. subflexifolium stat. et comb. nov. The var. subflexifolium is based upon Grimmia subflexifolium Mull. Hal., an alpine and apparently endemic taxon which has been ignored since its description in 1898. The distribution, ecology, and affinities of Racomitrium curiosissimum, a recently described but little documented South I. endemic, are outlined.
