64 TASMANIAN BRYOrHYTA, 



Anevra fasmanica, St. — Rather small, decumbent, sel- 

 dom exceeding 1 cm., fiat, much divided into short 

 branches, 1-2 mm. wide, rarely suberect, and with ex- 

 panded tips, very narrow, almost terete at the base, apex 

 obtuse in section plano-convex, 8 cells thick in the middle, 

 margin acute, but not winged, surface coarsely papillate. 

 Calyptra large, broadly cylindric, coarsely papillose. Cor- 

 licular cells 20 fx., medullaries 60 ^. 



Slopes of Mount Wellington. 



Aneura crecta, St. — Procumbent, widely spreading, 

 vaguely branched, yellowish-green or more or less brown, 

 1-2 cm. long, numerous branches, ascending or erect, about 

 5-10 mm. long, flat or concave, simple or seldom branched. 

 1-2 mm. wide, with obtuse apices, about 5 cells thick in 

 the middle ; dorsal cortical cells hexagonal and brown 

 walled, ventrals longer, marginal cells often colourless, 

 rectangular, but variable. Cortical cells 40 ^., medullaries 

 very large. 



Very common. 



Aneura coclileata, Hf. et T. — Medium size, densely 

 pulvinate, the branches erect, and usually stronglv con- 

 cave at the tips. Branches simple, or with few lobes, erect, • 

 2-3 mm. wide, broader and concave at the apex, 4-5 cells 

 thick in the middle, margin acute, with one or two series 

 of large quadrate hyaline cells, cortical cells rather large, 

 those of the ventral surface of very irregular shape. 

 Calyptra ohlong, 2 mm., coarsely papillate. 



Slopes of Mt. Wellington. New Zealand. 



f. Iirhcno/J<^s. — Branches more lobed, flatter, and less 

 erect. 



Mt. Wellington. 



Aneura alcicorne. Mitt. — Small, slender in dense, pul- 

 vinate masses or singly amongst moss, pale green or when 

 exposed very dark, with green tips. Ascending, linear, or 

 almost terete, to 1 cm long, 0.3-0.6 mm. diameter, 

 branches few, short or lono-, similar, biconvex, with obtuse 

 margins, cortical cells, little smaller than the medullaries. 

 Calyptra half-way up the branch, clavate 3 mm. long. 



Small forms are very similar to A. r/racil/.'i, but the 

 margins are obtuse, and the apex of the calyptra without 

 the ring of pilose hairs of that species.
