be referred there; and in any case, apart from this character, the other 
characters given for P. australasicum would not appear by themselves to 
justify its separation from АР. fortile. The specimens in Hampe's Herbarium 
show capsules almost or quite smooth ; but there is a suspicion of a rib about 
some, and I should doubt whether it is really distinct from P. tortile in this 
character if more material were studied. But without further knowledge 
I do not feel able to give an opinion ах to whether there is more than one 
New Zealand species of this group.
