Has. On dead Fern-trees: Acher (Gunn, 1625.) 
A very remarkable species.— Capsul E. a large oblate apophysis, pale (as if pulverulent), of firm texture, 
scarcely altered when dry. Seta red. Leaves tinged with red, pale, not crisped when dry.— Whole plant about j 
inch in length. Dioicous ? 
Tribe XVI. BuxBAUMLE. 
Gen. XLIII. BUXBAUMIA, Haller. 
Calyptra cylindrico-campanulata, parva, operculum tegens, fugax, coriacea, interdum latere fissa. Peri- 
stomium duplex: exterius nunc membrana solida irregulariter inciso-emarginata e strato cellularum duplici 
conformata opaca et obscure rufescens, nunc dentes ineequales moniliformi-articulati vallorum instar angust 
solidi; interius membrana albida tenerrima in conum tubulosum producta valde acute-angulato-plicata, 
siccitate leviter tortuosa angulosa. Columella in operculum exserta et cum eodem decidua.—C. Mueller, 
Syn. Musc. i. p. 151. 
1. Buxbaumia Tasmanica (Mitten, in Journ. Linn. Soc. ined.) ; * B. indusiata simillima, foliis 
parvis ciliatis, pedunculo nitido subscabro, theca suberecta ovata superficie superiore planiuscula immargi- 
nata, inferiore convexa, operculo conico." 
Has. Cheshunt, Arcker. 
Closely resembling B. indusiata, but differing in its nearly smooth, shining seta.—Peristome apparently com- 
posed of smooth bladdery cells, scarcely free from the internal membrane.—All the capsules yet seen, although fully 
formed, are too immature to show the perfectly developed peristome, or if the external capsular wall rolls off as in 
B. indusiata.— Mitten, l.c. 
Tribe XVII. PoLYTRICHACEZ. 
Gen. XLIV. POLYTRICHUM, Dill., Linn. 
Peristomium simplex; dentes 32-64, raro 16, breves, ligulati, inflexi, duriusculi, e filis inarticulatis 
duplici lamina dispositis contexti, haud hygroscopici, epiphragma inter apices dentium sustentum. Calyptra 
parva, cuculliformis, plerumgue indumento villoso vestita, interdum nuda,
