Abstract
Specific criteria in Astelia and Collospermum are discussed, including those based on the scales of the leaf indumentum. In the wholly Australasian subgenus Tricella names of 13 taxa are typified, and the net result of nomenclatural and taxonomic changes is to increase the number of rccognised species from five to 10: A. fragrans Col.; A. grandis Hook. f. tx Kirk; A. chathamica (Skottsb.) L. B. Moore comb. nov.; A. australiana (J. H. Willis) L. B. Moore comb, nov.; A. nervosa Hook. f. (non Banks et Sol.); A. petriei Ckn.; A. skottsbergii L. B. Moore sp. nov.; A. nivicola Ckn. ex Cheesem. var. nivicola; A. nivicola var. moriceae L. B. Moore var. nov.; A. graminea L. B. Moore sp. nov.; A. psycbrocbaris F. Mucll. In subgenus Astelia A. solandri subsp. hookerana (Kirk) L. B. Moore comb. nov. is equated to subsp. A of Wheeler, and reasons are given for regarding Collospermum spicatum (Col.) Skottsb. as based on juvenile flowering plants of other species. A table shows how the names here adopted can be equated to those used in earlier treatments, and the paper concludes with a synoptic key to the taxa of Astelia and Collospermum recognised in Australasia, and a brief account, supported by maps, of distribution pattterns of the New Zealand asteliads.
