﻿102 Dixon: New and rare Australasian 



showing a few other minor differences from M. rigescens, e. g., 

 the branches more slender and rigid, the leaves a little longer and 

 narrower, the operculum with a longer subula.

Habitat: Evans Flat, Tuapeka County, Otago, New Zealand,

A species of somewhat doubtful position in the genus; the leaf- 

 structure, the rudimentary cilia, and perhaps the exothecium 

 tissue, would place it in Eupohlia, while on the other hand the 

 high basal membrane and well-developed processes of the inner 

 peristome seem to refer it to Lamprophyllum. In any case it is 

 nearly related to P. leptocarpa (v. d. B. & Lac.) Fleisch., and as this 

 is usually ranked under Eupohlia I place the present species there. 

 The plane-margined leaves, the inflorescence and peristome, both 

 inner and outer papillose, distinguish it from the above-named 

 and other species. Among the New Zealand species there are 

 none very closely allied, P. nutans being perhaps superficially
