82 TASMANIAN BRYOPHYTA, 



Aplozia alj)iiia^ Rod. — Stem weak slender, often 2-3 

 cm., green. Leaves mostly distant rotund, concave, nearly- 

 transverse, mostly 0.7 mm.; cells 17 ^,. ; bracts similar 

 tt> and about the size of the other leaves, free from the 

 perianth. Perianth fusiform tapering to a shortly 3-lobed 

 or nearly entire mouth, dorsal surface with an obtuse keel, 

 ventral surface with a broad deep groove, 2 mm. long. 

 Stunted forms have a shorter perianth with a wider 3-lobed 

 mouth and often a shortly bifid bracteole. 



Mt. Wellington Plateau. Cradle Mt. 



Forma stiiiulata. — In dense cushions, more robust, 

 branches often stoloniferous. Underleaves present, oblong, 

 rudimentary to half as long as the leaves. 



Cradle Mt. 



Aplozia lacerata, Rod. — Stems short in cushions, but 

 often hidden amongst moss or buried in humus bearing 

 only a few leaves in the upper portion, tender and pale, 

 sage-green. Leaves almost transverse oblong to nearly 

 rotund, concave 0.7 mm. ; cells 27 fj,.^ walls thin. Bracts 

 much longer than the leaves, narrow oblong, apex slightly 

 fimbriate, bracteole nearly as long as the bracts, ovate 

 obtuse, all adnate to the base of the perianth. Perianth 

 cylindric with three shallow plaits little longer than the 

 bracts, mouth nanrow to little constricted, deeply 3-lobed, 

 Icbes narrow laciniate. 



Mt. Wellington Plateau. 



Sphenolobus (Lindb.), St. 



Plants usually small, decumbent to erect; branches 

 few from the ventral angles of the leaves. Leaves small, 

 transversely inserted, 2-lobed or nearly entire, base de- 

 eiirrent or sheathing; cells rotund; underleaves absent or 

 rudimentary. Perianth terminal, ovate to cylindric, more 

 or less contracted at the apex. 



Very close to Loj)1iozia, but the leaves more concave 

 and transversely inserted. 



Sphenolobus perigonialis (TayL), St. — Very slender, 

 usually about 1 cm. long, dark livid green. Leaves oblong, 

 not crowded, decurving above, base broad stem-clasping, 

 apex to J bifid, lobes broad obtuse, 0.6 mm. long; cells 

 14 /i., cuticle irregularly nodulose. Bracts usually broad, 

 shortly 3-lobed 1.3 mm.; perianth broadly oblong", 2 mm., 

 3-5 plicate, mouth contracted with 3-5 short irregular lobes, 

 but perianth varies much in length, and is often quite 

 cylindric, with a very small contracted mouth.
