Quite distinct from all the species except the succeeding in the slender 
stems and rigid habit, with straight branches, minute leaves, straight, erect, 
and rigidly appressed when dry, the small elliptic capsule and hairy calyptra. 
Widely distributed over the North and South Islands, Tasmania, and 
Australia. I follow Brotherus in keeping the Australasian plant separate 
from the original M. microphyllum of South Africa, but I have not compared 
them critically, and do not know on what he bases the distinction. 
2. Macromitrium recurvulum C. M. in Hedwig, vol. 37, p. 143 (1898) 
(nec M. recurvulum Card. in Rev. Bryol., 28, p. 113 (1901) ). 
A very pretty little plant, of which I have a small specimen sent me, 
mixed with M. eucalyptorum, from Kopuaranga, Wairarapa, North Island, 
by Mr. W. Gray. The leaves are marke ly squarrose when moist and 
quite distinctly recurved at the apex when dry ; the seta is shorter and the 
capsule smaller ; otherwise it does not appear to differ from M. eucalyptorum. 
It has, I believe, not been recorded elsewhere since the original gathering 
by Beckett in the Waimakariri Gorge, South Island.

3. Macromitrium orthophyllum Mitt. in Journ. Linn. Soc., Bot., vol. 4, 
p. 79 (1859) ; Handb. N.Z. FI., p. 430. 
A very distinct species, robust, and known at once by the large leaves 
scarcely altered when dry, erect and appressed, or sometimes slightly 
twisted in a spiral. The seta is stout, about 1 cm. long; the capsule 
rather lerge, about 2 mm. long,* elliptic, becoming plicate after maturity. 
Calyptra naked, ofter split more highly on one side. 
Only North Island localities are given in the Handbook, but I have it 
from several stations in the South Island.

elliptic capsule, and large naked calyptra will generally aid in determining it. 
A widely distributed plant in New Zealand. 
*The measurements of the capsule are given without including the lid.
