Var. impolitum Gepp. var. nov. 



Eamuline leaves not shining, in the dry state less close y 

 appressed than in the type, plicate under pressure, more widely 

 acuminulate. 



PUNGO Andongo.— A yellowish green, creeping, widely casspitose 

 moss, found on rotting old trunks in Barrancos de Catete, and more 

 rarely on the bare ground in the same place ; with opercnlate fr. and 

 very fugacious calyptras, May 1857. No. 84. 



GoLUNGO Alto.— On trunks and branches of Edwardta luridain the 

 forests of Quilombo-Quiacatubia, at an elevation of 2400 ft. ; with old 

 fr. end of Feb. 1855. No. 164. Growing with Macromitrium lyco- 

 podioides on old trunks, especially on Edwardta, in the rocky woody 

 parts of Sobato de Quilombo-Quiacatubia ; July 1856. No. 144. Wel- 

 witsoh says he also gathered the plant at Alto Queta. 



2. E. bicolor Gepp sp. n. 



Plant closely and widely interwoven. Stem creeping, rooting, 

 pinnately branched, with leaves homomallous. Branches numerous, 

 ascending, curved, brunnescent below, flavescent above, terete- 

 julaceous, scarcely polished, obtuse, 3 to 5 mm. long, 0-4 mm. wide 

 when dry, I'O wide when wet. Eamuline leaves appressed when 

 dry, erecto-patent when wet, 0-85 mm. long by 0-375 mm. wide, 

 from a broad cordate base elliptic-ovate acuminate, slightly 

 hollowed, shortly binervate, with margins erect or slightly re- 

 curved, minutely serrulate above middle ; alar cells quadrate 

 numerous, ascending to ^ length of margin, O'Ol to 0'015 mm. 

 diam., with primordial utricle contracted, dense ; upper cells 

 vermiform-elongate (0'05 by 0'006 mm.), smooth, with walls 

 lutescent. 



HuiLLA. — A densely and widely csespitose moss, covering the older 

 tree-trunks on the northern and western sides ; on nearly lifeless bark 

 in the elevated woods of Monino near Lopollo ; without fr. Apr. 1860. 

 No. 8. 



This sterile specimen appears to belong to the present genus. In 

 habit and in leaf-structure it is related to E. subjidaceum Paris, but 

 difEers in the shape of the leaves which are oblong-ovate, half as wide, 

 much less excavate. The leaves approach in shape more nearly to 

 those of E. Schweinfurthi Paris (Index Bryolog. p. 437), but are much 

 less excavate and have much less visibly reflexed margins. 



35. TRACHYPHYLLUM Gepp gen. nov. 



A genus of the family Entodontem, nearest to Erythrodontium 

 and differing in the papillate dorsal surface of the leaves and in 

 the inclined, lopsided theca. It is distinguished from Pterigyn- 

 and/rwm by the very numerous alar cells of its leaves. 



Stem prostrate, more or less pinnate ; branches ascending, 

 julaceous ; leaves appressed (apex patent) when dry, very patent
