I have seen no other records from the South Hand. ‘th the North Island

e New Zealand plant was first recorded as es obtusifolius Hook., but 
of late years has been generally known as Z. neglectus. I have failed to 
ascertain any -published ground for separating it ee the Indian species. 
The name neglectus as a vali publication rests upon C. Mueller’s description 
in Hedwig., vol. 37, p. 133. There he describes it without reference to 
Z. ous, and indeed without reference to the New Zealand plants 
recorded un that name in the Handh. N.Z. Fl., &c. He bases it on a 
specimen OZ. ieee s Hpe. in sched. 1868; Nova Seelandia, sine loco 
natali ; ight.” The characters he gives are entirely consonant with 
Z. obtustfolius Hook., except that he describes the peristome as single. 
The New Zealand plant, however, has the peristome constantly ae 
and there is no reason to suspect that this particular specimen differs 
that respect from the ordinary plants 
I have examined Hampe’s herbarium to see oT that author throws any 
light on the question; the only specimen of Z. neglectus there is a New 
Zealand plant without collector’s name, on the iabel of which Basing has
