Soc. Bot. 45: 477-510. ph. 28, 29. 1922.) — A brief introduction discusses the 
opportunity for the study of "discontinuous distribution" afforded by the New 
Guinea flora, and its decidedly endemic character. The Wollaston Mosses com- 
prise some 35 different forms, the following being proposed as new: Bryum papua- 
num Dix., Hymenodontopsis rhizogonioides Dix., Breutelia longicapsularis Dix., 
PogonaUim Klossii Dix., Dawsonia crispifolia Dix., D. limhata Dix., Chaetomttrium 
laevisetum Dix., C. perlaeve Dix., Thuidium scahribracteatum Dix., Ectropothecium 
dentigerum Dix., E. aurem Dix., E. laxirete Dix., Trichostelium capillarisetum Dix., 
Hypnodendron parvum Dix. ; and the following new combinations : Thysanomitrium 
Blumii (D. & M.) Dix., Plagiotheciopsis oblonga (Broth.) Broth., Sematophyllum 
leptocarpon cylindricum (R. & H.) Dix.; the new subgenus Leiocarpos is also 
proposed in Hypnodendron. Further, a key and discussion is given for all New 
Guinea species of Dawsonia, with an abundance of critical notes on other species. 
The circumstances attending the publication of Herzog's Hymenodontopsis are 
also mentioned. — The second part of the article lists 48 species of mosses from 
the Port Moresby District, Brit. New Guinea, with many notes and synonyms. 
CampylopMS suhcomosus Dix., Leucobryum cyathifolium Dix., Syrrhopodon duri- 
golensis Dix., ?Rhizogonium orbicular e Dix., Pterobryella papuensis Dix., Acantho- 
cladium Clarkii Dix., Trichosteleum grosso-mamillosum (C. Mull.) Par. ined., 
T. sematophylloides Dix., Sematophyllum flagelliferum Dix., S. roseum Dix., are 
proposed as new, and Leucobryum candidum speirostichum (C. Mull.) Dix., as 
a new combination. 
H. N. Dixon. — Rhacopilopsis trinitensis Britt. & Dixon. (Journ. Bot. 60: 
86-88. 1922.) — A careful study of original material shows that Hypnum trini- 
tense C. M. is the same as Ectropothecium trinitense Mitt., Hypnum chlorizans 
VVelw. & Duby, and Hypnum Pechuelii C. M. The original descriptions of Mueller 
and Mitten, as far as fruiting plants went, seem to have been based on mixed 
material; no constant differences were to be found between the African plants 
described by Mueller under Hypnum sect. Dimorphella, and the Trinidad- 
Guiana material. 
H. N. Dixon. — Some new Genera of Mosses. (Journ. Bot. 60: loi-iio. 
PL 564. 1922.) — The article describes and figures seven species, each representa- 
tive of an undescribed genus; there is also a key to the genera of Funariaceae, 
bringing up to date that given by Brotherus in Engler & Prantl. The new genera 
and species are, family names being in parentheses: Nanobryum Dummeri Dix. 
(Dicranaceae) from Uganda and Cape Province, Chionoloma induratum (Mitt.) 
Dix. (Pottiaceae-Trichostomeae) from Burmah, Beddomiella funarioides Dixon 
(Pottiaceae-Pottieae) from Nilgheri Mts., (Edipodiella austrahs (Wager & Dix.) 
Dixon (QEdipodiaceae) from Natal, Chamaebryum pottioides Ther. & Dix. 
(Funariaceae) from Cape Town, Physcomitrellopsis africana Broth. & Wager 
(Funariaceae) from Natal, Dimorphocladon bornense Dixon (Hookeriaceae) from 
Sarawak.
