250 TASMANIAN BRYOPHYTA, 



R.S. TAS. 



falcate, external surface strongly papillose, cells rotund 

 strongly incrassate 6>, nerveless. Perichaetials much 

 longer. Capsule exserted, with a broad pale band at the 

 base. 



Very common on mountains. 



Andrcaea acuminata Mitt. 

 Syn : Andreaea erubescens CM. 



Ked-brown in dense cushions. Stems 1 cm. in dry, to 3 

 cm. in shaded jilaces. Leaves crowded, base broad, sheath- 

 ing, colourless, lamina geniculate at the base ; patent, in 

 curved above, ovate, acuminate, concave 0.5-0.7 mm. the 

 wings at junction of base and lamina crenate and much 

 incurved, external surface bearing short obtuse papillae ; 

 nerveless; cells rotund, strongly incrassate 5-6/* Perichae- 

 tials much longer. Capsule immersed. 



Differs from A. ijetro'phila in the broader leaf. 



Common on mountains. 



Andreaea tenei^a CM! 



Stems very slender with many branches in the upper 

 part or in dry situations shorter and pulvinate, greenish- 

 brown, at least towards the apex. Leaves patent, genicu- 

 late from a sheathing base, incurved towards the apex» 

 narrow lanceolate, acute, margin involute, 0.7 mm., nerve- 

 lees, external surface obtusely papillose; cells some rotund 

 others oblong, 8 — 8 x 16/ii, long rectangular in the centre 

 base. Perichaetials slender 1.5-2.5 mm. Capsule included 

 or exserted with a broad white base. 



Besides habit the leaf-structure is very distinct. 



Summit of Mt. Wellington. 



Andreaea eximia CM. 



Stems short, black, the lower part nearly bare, the leaves 

 clustered at the apex. Leaves linear from a narrow sheath- 

 ing base, acute or with a colourless apex, 1-1.5 mm. ; cells 

 rotund, translucent, the papillae bold. Perichaetials not 

 much longer with a very broad base and a short acuminate 

 apex. Capsule small, with a broad pale base shortly or 

 not at all exserted. 



The narrow nearly flat dark leaves clustered at the top 

 of the short stem sufficiently distinguishes the species. 



Very common at a high altitude. 



Andreaea amblyophylla CM. 



Stems short, dichotomously branched, seldom exceeding 

 1 cm., dark red, but the tips usually red or yellowish-brown.
