leaves. Capsule oblong, suberect, substrumose ; operculum with a beak as 
long as the capsule. Male inflorescence nestling amongst the fibrils of the stein. 
— D. bracliypelma, C. Muell. in Bot. Zeit. 1851. 550. 
Var. 0. rigid urn, FI. N. Z. Stem stouter ; leaves less crowded, more rigid, spreading, 
subfalcate. 
Common throughout the islands and in Lord Auckland’s group. (Tasmania, Aus- 
tralia, Polynesia, Chile.) 
Of D. dickotomnm, Bridel, said by Montagne in Vov. au Pole Sud, 297, to have been 
brought by llombron from Lord Auckland’s group, I know nothing. It is a Bourbon 
species. 
12. DICRANODONTIUM, Brid. 
Erect, tufted, usually terrestrial, dioecious mosses. Leaves imbricating all 
round tiie stems, with broad sheathing bases and a broad nerve. Fruitstalk 
terminal, curved when moist. Capsule pendulous or decurved, owing to the 
curvature of the fruitstalk, equal or unequal, striate or plicate ; teeth 16, 
linear-lanceolate, remotely articulate, 2-fid to below the middle or to the base, 
divisions unequal, subulate ; annulus narrow, persistent. Operculum oblique, 
subulate. Calyptra cucullate, smooth, not fringed at the base. 
A small genus, chiefly insular and tropical, similar in habit and characters to Campylopus, 
but differing from that genus in wanting the lamellate leaves and fringed base to the calyp- 
tra, and from Dicranum in the teeth and pendulous capsule. Mitten refers the species to 
Leptotriclium , Hampe. 
Leaf suddenly contracted from a broad base 1. D. flexipes. 
Leaf linear-lanceolate 2. JD. lineare. 
1. D. flexipes. Mitten, mss. — D. proscriptum, FI. N. Z. ii. 67, not of 
Hornschuch. Stems slender, simple, ^ in. long. Leaves falcate, secund, 
vellow-green, brown when old, base sheathing, then rigid setaceous or capil- 
lary, quite entire or serrulate about the middle ; nerve stout. FVuitstalk 
curved when moist, straight when dry. Capsule elliptic, substriate when dry; 
annulus large. Inflorescence dioecious. 
Var. 0. Taller; leaves lax, squarrose, broader and more sheathing below. 
Var. y. Stem short ; leaves crowded, falcate. 
Northern Island : Bay of Islands, etc., J. I). H., Colenso, etc. Mr. Mitten points out 
that this differs from the D. proscriptum of St. Helena in the gibbous capsule, small struma, 
and less suddenly subulate leaves. 
J- D. lineare, Mitten, mss. Stems very short, tufted, less than i in. 
high. Leaves pale-green, soft, spreading, linear-lanceolate ; nerve con- 
tinuous, keeled ; margins serrulate ; perichaetial elliptic-ovate, convolute. 
Fruitstalk as long as the perichaetial leaves. Capsule curved, ovoid, subequal, 
subapophysate, with 8 furrows when dry ; teeth slender, yellow, broad ; 
operculum conic-subulate, half as long as the capsule. Inflorescence monoe- 
cious. 
Middle Island: Canterbury, Travers. Distinguished from all others by the cauline 
leaves not subulate from dilated bases, by the minutely serrulate leaves aud defined nerve.
