MOSSES OF NEW ZEALAND. 435 
marginem versus quadratis vel subquadratis, parum majoribus, juxta costam 
tantum in paucis serichus paullo elongatis breviter oblongis. Flos masculus 
capituliformis, terminalis; bracteæ extern foliis similes sed breviores, 
interne breviter late ovate, subacute, vel suborbiculares, eymbiformes, 
enerves ; antheridia clavata, breviter stipitata. Cetera ignota. 
Hab. Mt. Cook district, South I., 2500-5000 ft. ; leg. Michell (No. 66). 
Named after Dr. Michell, who was associated with Mr. Murray in collecting 
mosses on frequent occasions. 
A distinct species, uearly allied to A. australis, F. Muell., from Australia, 
but differing from that in the simple, slender, laxly foliate stems and the 
leaves which are obtuse and broud at the apex, not in any way tapering or 
acute, In A. australis the lower leaves expecially taper gradually to a sub- 
acute point, and are strongly incurved at the apex and often subeucullate, 
It is also very close to A. e/ntoniensis, R. Br. ter., of which no specimen 
appears to exist in Brown’s herbarium, and which unfortunately I have not 
been able to see. The figures, however (Trans. N.Z. Inst. xxv. p. 276, 
1892), show a very distinctly narrower nerve, and the lower leaves at least 
are acute, whilst, from the deseription, the plant is differently coloured (pale 
above, dark below), and the lower leaves are linear-lanceolate and acute ; 
no reference is made to the cells. The uniformly short, broad and broadly- 
pointed leaves in our plant seem to distinguish it at once from all the 
hitherto described species of this group, though the two species referred to 
approach it closely in the form of the upper leaves. 
АХОВЕЖА AQUATILIS, В. Br. ter., is а far larger, very robust plant, with 
longer leaves having acute points. A. lanceolata, К. Br. ter., is more robust, 
with acute leaves, narrower nerve, and very dense areolation.

Dirricnum AUSTRALE, Mitt. Mauriceville, Wairarapa, North T., 1909 
(Gray, Nox. 62, 82), c.fr. The specimens of this species in Herb. Hook. at 
Kew show a great variation in the dentation of the subula, from sharply 
spinulose to entire or subentire.
