92 BRYOLOGY OF NEW ZEALAND. 
C. arboricola in the nerve, having both ventral and dorsal stereid bands. 
Pom the latter it is known at once by the large inflated alar cells, as well as 
" by the larger, longer leaves, which (except the comal, floral ones) do not end 
in the distinct white hair-point which is a marked character of that plant. 
The capsules are aggregated in dense heads, as in many species of Cam- 
polonde It is found also in southern and equatorial South America. Cardot, 
—— following Paris, gives also the Auckland Islands, but I am inclined 
to think this is an error derived from the citation of “ Auckl and, Knight, 
in ae Handbook. There are no Australasian specimens in the British 
Museum collection except those gathered by Colenso and Knight in New 
Zealand, nor are there any at Kew beyond the New Zealand plants, 
among which there is a single specimen from the South Island—viz., 
“ Otago, Hector.” 
The nerve-section actually consists of a row of “ Deuter” cells, with 
fairly developed band of dorsal stereids, but on the ventral surface a 
single series of superficial cells almost equal to the “ Deuter” cells, and 
only a very few stereids interposed between these two series, so that the 
general appearance is more like that of Hucampylopus than typical 
Thysanomitrium, 
DicRANODONTIUM Bruch & Schimp., Bry. Eur., fasc. 41, 1847. 
Stems slender, leaves setaceous from a wider, usually short base ; nerve 
broad and flat with een of Campylopus (Palinocraspis) : ; basal areola- 
tion rectangular, usually with a more or less distinct border of extremely 
narrow cells ; alar cells Pao, inflated. Capsule symmetrical, on a curved 
es calyptra usually naked at base; peristome-teeth cleft to base into 
wo subequal subulate divisions, remotely articulate 
“a Baie : North America; with two or ee species in the 
Southern Hemisphere (South Africa, New Guinea, Tasmania). A genus 
mostly of the north temperate regions. The two species isieed to this 
genus in the “ Handbook of the New Zealand Flora ” do not properly belong 
here, but to Campylopodium.
