C. Miller in the — Muse. Fr., p. 263, under Dicranum -(§ Microcam- 
pylopus), cites D. nudum Ham from Australia, “die aber auch auf Neu- 
seeland vorzukommen ocianes A specimen labelled “65. New Zealand ” 
occurs in Hampe’s herbarium, without collector’s name. The position of 
the plant appears to me very uncertain; I have examined the type care- 
eels not that of Dicranodontium ; the sixteen teeth are distant, lingulate- 
lanceolate, flat and undivided for the pose part of their length, only 
divided for a short distance in the upper part ; they are bright orange with 
deep red-brown trabeculae, faintly papillose below, distinctly vertically 
striolate above. The capsules are not estrumose as descri y Hampe, 
but when in good condition show a slight but distinet struma. It appears, 
therefore, to belong either to Campylopus or anum, and the curved 
seta would seem to place it here, perhaps, as C. Miiller ranks it, with the 
eungene, 5 wcrocampylopus 
I do not know of any other station for it beyond the original (unknown) 
locality. 
EXCLUDED SPECIES. 
C. xanthophyllus Mont., Middle Island, Akaroa, Raoul; Dusky Bay 
Lyall (cf. Fl. N.Z., ui, 68), 1 is better dropped. The authors are very doubtful 
about the det ermination ; there are no specimens in Hooker’s herbarium 
. xanthophyllus Mont. (1845) is referable to C. truncatus C. M. (1844), and 
a South American species.

This plant, which as far as I know has been chiefly found in the North 
Island, principally near Auckland, has much the appearance of a tall, 
rather robust Campylopus. When in fruit the longly fringed calyptra, and 
the narrow, smooth, symmetrical capsule, will readily identify it. Sterile 
plants differ from all the New Zealand species of Campylopus except
