Abstract
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 differentiated, inflated alar cells, rudimentary double costae, 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 {Pulchrinodus} becomes known, the genus is tentatively placed within the Pterobryaceae (sensu lato). However, 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 Caledonia, south-western Tasmania, and in the North and South Islands of New Zealand.
