some degree of variation, and a greater length is perhaps generally 
associated with a lesser thickness, the differences are exceedingly 
slight, and I have certainly seen no seta which could fairly be 
deseribed as ‘‘ crassa.’ 
The serrulation of the leaves offers no distinctive character, but 
all degrees may be found from a fair degree of denticulation to 
perfectly entire; the margin of the leaf is equally elusive, it being 
frequently recurved in Bp aed on the same stem where the ee 
are plane-margined. 
e perichaetial leaves vary considerably, and I had hoped to 
find some distinctive character the sah since in the present genus 
these may be a very safe guide in the determination o species 
where other characters afford little heli: I have, however, found the 
different forms entirely unassociated with any other of ‘the distin- 
guishing characters suggested above. The bracts may be shortly 
and broadly Sage aaa or gradually narrowly acuminate, or quickly 
attenuated from a wide, sheathing base to a subfiliform, denticulate 
subula; but hee are never very longly and finely acuminate or 
subpiliferous, nor very widely spreading. 
In all probability other Australian plants such as R. calliferum 
Hampe & Geheeb, and R. callidioides Hampe & C. M., are referable 
here, aie I have not studied them closely. 
H, mundulum H. f. & W. certainly belongs here; it is a fairly 
robust sloht with the oid capsules of a deep purp lish-brown , but in 
other respects exhibits no difference from moenum except in 
respect of the lid, aeined ae gine than he capsule.’’ I have 
examined all the plants in Hooker’s and Wilson’s herbaria, and I 
find only four lids, two eahaderatly shorter than the caps sule and 
with Tathet stout bea ks, and one of tact otnameied the same length 
as the capsule, and also r ather stout. These Gy form figured 
in the Fl. N.Z. Wilson has the following MS. **"H. may be

remains whether it is deserving varietal rank. should certainly
