Neither rate nor C. Miller was acquainted with the preceding species 
as a New Zealand plant. In his pee on of A. ges C. Miiller 
makes no reference to C. ewphorocladum (or flexipes), compares his 
plant with Campylopodium sigslisenes (H. i & W.), eh 8 a very different 
plant now placed in Campylopus (C. Holomitrium Jaeg.). Consequently 
his description of be present plant takes no account of its differences from 
C. euphorocladum ; in fact, it 1s far more applicable to that species than to 
the one which is bios described! The only point in the diagnosis — 
is more applicable to C. lineare is the sabia of the base as “ paru 
dilatate vaginata.” The same remark applies to Stirton’s description of 
his Gr. Buchanani. I have, however, g are specimens of the original gather- 
ing made by Buchanan, “ Wellington, N.Z., leg. J. Buchanan,” sent me 
by Mr. D. Petrie, from which I Save: been able to ascertain not only the 
distinguishing characters of what is no doubt a good species, but also, with 
scarcely a doubt, its identity with the Dicranodontium lineare Mitt. of the 
Handbook, no specimens of which, unfortunately, are to be found in Mitten’s 
herbarium, or in either of the national collections in London 
The sheathing portion of the leaf is, as pointed out by “Mitten, much 
narrower than in C. ewphorocladum, being ovate-lanceolate rather than 
widely ovate or pboe ate; the subula is rather stouter, and the lamina 
usually (I believe, special extends much higher up in the leaf, frequently 
remaining in 1-3 rows of cells almost to the extreme apex. The upper 
cells are shortly ftlisellng % and the greater part of the margin of the 
subula is distinctly serrulate, while the projecting transverse walls of the 
cells render the surface of the leaf finely scabrous or rugulose. The back of 
the nerve is also somewhat denticulate. 
The inflorescence is, as described by Mitten, autoicous ; not dicicous, 
the perichaetium, the perigonial bracts ovate to ovate-lanceolate, the 
antheridia few and small, — 0-02 mm. long, narrowly clavate; para- 
physes few and inconspicuou

The original locality, in Canterbury (Travers), and Buchanan’s station. 
near Wellington, appear to be the only known records.
