Abstract The genus Pulchrinodus is established for the species long known as Eucamptodon inflatus. Based upon the presence of pseudoparaphyllia, incrassate and porose leaf cells, strongly differen- tiated, inflated alar cells, rudimentary double cos- tae, diplolepideous-type axillary hairs, an unbranched habit, stems with numerous arrested branch primordia, and rudimentary, well spaced leaves at the base, a well developed stem central strand, and near absence of rhizoids, Pulchrinodus is placed in the Leucodontales (sensu Buck & Vitt 1986). Until such time as the sporophyte of Pul- chrinodus becomes known, the genus is tentatively placed within the Pterobryaceae (sensu lato). How- ever, its acrocarpous habit, antheridial splash cups, and unusually long-stalked antheridia are features not found in other members of the Pterobryaceae. Pulchrinodus inflatus occurs in southern New Cale- donia, south-western Tasmania, and in the North and South Islands of New Zealand.
