B. DiVARiCATA {Mitten). Dioica, caule elongato inferne tomentoso 

 subsimplici, foHis e basi brevi caulem araplectente cellulis hyalinis 

 pluribus ad angulos marginum congestis divaricatis lanceolatis plicatis 

 papulosis margine serrulatis nervo tenui excurrente mucronatis sic- 

 citate subflaccidis, perichaetialibus ovatis integerrimis nervo angus- 

 tissimo, theca in pedimculo elongaio horizontali oblongo-ovali coUo 

 pyriformi attenuate, operculo conico, peristomio normali, 



Hab. New Zealand, Colenso, Dr. J. D. Hooker, Knight, Lyall, Sinclair ; 

 Tasmania, Cheshunt, Mr. Archer. 

 Resembles the larger states of -B. pendula, but differs in its divaricated 



leaves, which have, when dry, a subflaccid appearance, a differently 



formed base, and the stems almost simple. 



B. pendula, which has been much misunderstood, varies greatly in its 

 size, being sometimes not larger than the usual states of Philonotis 

 fontana, as in the original specimens gathered by Menzies, at others as 

 large as B. gigantea, Schwsegrichen's figure 161 having been taken from 

 this state ; but the capsule is not erect. The Hypnum elongatum. Hook, 

 fil. et Wils. in Crypt. Antarct. t. 60, is certainly of this genus, and may 

 be a form of B. pendula. Hypnum consimile. Hook. fil. et Wils. in Crypt. 

 Antarct. t. 60, is also to be referred to Breutelia. 



B. Sieberi, of which some specimens have been gathered by Mr. Old- 

 field, may be thus characterized : — 



B. Sieberi, Hornsch. in Muse. Sieber. No. 12. Dioica, caule procum- 

 bente suberectove ramuhs brevibus fasciculatis ramoso innovante 

 iterumque ramoso inferne dense radiculoso, foliis hand nitidis e basi 

 brevi erectiuscula ad insertionem contracta patentibus lanceolatis 

 estriatis nervo angusto in acumen setaceo-pungens excurrente mar- 

 ginibus serrulatis inferne recurvis cellulis omnibus elongatis an- 

 gustis papillosis, perichaetialibus conformibus, theca in pedunculo 

 rubro unciali apice flexura angusta pendula ovali plicata, operculo 

 depresso conico, peristomio parvo normali ? flore masculo foliis qua- 

 druple latioribus late ovatis patulis nervo superne evanido. 

 Hab. Tasmania, Mount Wellington, Dr. J. D. Hooker and Mr. Oldfield ; 

 New Holland, Sieber. 



Stems in all the Tasmanian specimens scarcely exceeding an inch in 

 height; colour of the foliage yellowish-green, without gloss; leaves 

 narrow; cells in the upper portion elongated, everywhere distinctly 

 papillose ; alary cells few, indistinct. In all the allied species the cells 

 of the upper portion of the leaf are shortened. 



B. PLICATA {Mitten). B. divaricates simillima, foliis siccitate curvatis 

 e basi erecta plicata divergentibus lanceolatis nervo percurrente mar- 

 ginibus arete serrulatis cellulis basi angustis elong-atis pellucidis 

 utrinque ad latera seriebus pluribus hjalinis superioribus quadrato-
