MOSSES OF NEW ZEALAND. 455 
Th. pumilum from Tasmania, where it was gathered on Mt. Wellington by 
Mr. W. A. Walker, in 1890, and at Russell’s Falls, Russell’s Falls R., 
Upper Derwent R., in 1909, sent me by Mr. J. A. Wheldon. 
LEMBOPHYLLACEÆ. 
CAMPTOCHÆTE RAMULOSA (Mitt.), Jaeg. Mt. Cook district (Murray, 
No. 70). 
C. ANGUSTATA (Mitt.), Jaeg. Mt. Cook district (Murray, No. 100). I 
place this here with some hesitation. It agrees with а plant, collected by 
Knight, in Lindberg’s Herbarium, and also with specimens in. Bescherelle's 
Herbarium ; but it has not (nor have they) the flattened secondary stems 
deseribed by Mitten and Brotherus. 
LEwBoPHYLLUM DIVULSUM (Hook. f. & Wils.), Lindb. Waitakarei Hills 
(Murray, No. 10). On wood, Mt. Cook district (Murray, No. 93), сЇт. This 
form has the leaves usually nerveless, though some leaves show a trace of 
nerve. "The presence of а short single nerve in this species is usually held 
to be a crucial character ; but it is not always reliable. I have had similar 
forms with the leaves more or less regularly nerveless sent me from 
Gippsland, Australia, leg. J. R. Murdoch, comm. G. Webster. In. Wilson's 
MS. notes in his herbarium on the type specimen (“ Gunn, 1686, Van Diemen's 
Land, Z. dirulsum, MSS.) he has sketched three leaves, one showing the 
single nerve, the other two nerveless, with the note: © fol. minutissime 
serrulata ..... ; sometimes nerveless ; often faintly nerved halfway.” 
HOOKERLIACE.T. 
DISTICHOPHYLLUM PULCHELLUM (Hook. f. & Wils.), Mitt. Waitakarei Hills 
(Murray, No. 22), с.т. Hooker and Wilson in the * Handbook’ erroneously 
describe the seta as rough above. 
PTrERYGOPHYLLUM DENTATUM (Hook. f. & Wils.). Mt. Cook district 
(Murray, No. 131). А few fragments only. The distribution is generally 
Antarctic, but it has not been previously recorded from New Zealand. It is 
doubtfully distinct, however, from P. nigellum *. 
* There seems no adequate reason for dropping the name dentatum under which the 
species was first published (Hookeria dentata, Hook. f. & Wils. in Lond. Journ. of Bot. 
1844, p. 550). It is not clear why the name should have been altered to denticulata, That 
dentata was not a lapsus calami is evident from the original description: “ foliis . . . . grosse 
dentatis," ete. It is referred to also in Fl. N. Z. ii. pp. 124-5 as “ H. dentata, Hook. f. & 
Wils.” Whatever the cause, dentata was the original name under which the species was 
published, and under which it should stand.
