arista, often equal in length to the rest of the leaf. These are very fragile, 
and nearly always broken off in the older leaves, but the younger leaves 
usually show them at the stem-apex, where they appear as a penicillate 
tuft. 
twisted round the stem, but are spirally twisted on their own axis, and 
have their apex strongly enrolled or hooked; they take. in fact, much 
the position of the leaves in M. gracile. They are usually very regularly 
and uniformly twisted, and exhibit a very prett arrangement, often of a 
spiral tendency; but this is owing to the spiral position of the leaves on 
the stem, not to a spiral elt round it 
I have M. retusum from several prac ai in the North Island where it 
was first recorded ; tl have seen it from only one locality in = South 
Island—viz., Pine Hill, Dunedin—whence Mr. Petrie sent it to m

In addition to 2 character mentioned above, this species differs fr 
M. retusum in the leaves nearly erect when moist—-there widely sceeadirip 
—and in the cells esa more distinctly defined. 
No specimen of M. aristatum Mitt. exists at Kew, but Mrs. Britton 
has kindly allowed me to see part of the original gathering (Auckland, ex 
herb. Buchanan), and I have been able to compare this with Lindberg’s 
species, and find the two to be absolutely identical. 
Mr. James Murray collected it in nest also in the vicinity of Auckland. 
I know of ‘no other recent records; Lindberg’s original plant is only 
recorded as “ e Nova Zelandin (Coll. Rails): inter Leptostomum macrocarpum.”

In its usual forms a very pretty species; the long, straight branches 
passing from yellow-green above to bright orange-brown below. The 
leaves are very on all along the branches, which are = thas very
