104 TASMANIA N BRYOPHYTA, 



rent, ventral margin more curved armed with few bold 

 teeth, apex truncate rotund armed with 2-4 bold spines; 

 cells 36 /i., trigones small or none. Underleaf large reni- 

 form very broad, with 6-8 shallow lobes armed with bold 

 spines, lower underleaves small and simpler. 

 Blue Tier. Mt. Field. 



ChilosrypJrus cordifoUus, Rod. — Robust, 4-6 cm. long, 

 densely pulvinate, rigid, yellow. Leaves erecto-homomal- 

 lous, closely imbricate, alternate, rotund, 1 mm. lo-ng, 

 rather broader than long, both bases cordate and free, 

 margin entire, cells towards the margin 16 jx , lower ones 

 33 yit., trigones as large as the cells confluent, surface 

 smooth. Underleaves rotund, concave, imbricate, free, 0.7 

 mm. long, margin entire or with about 6 obtuse angles. 

 No perianths present, but a group of archegonia termina.fc- 

 ing the shoot, thus bearing the character of LopJiocoIea, but 

 habit and leaf structuree is typically of Cliiloscyijhus. 

 Possibly it is this plant that Stephani describes as Lopho- 

 colea tumid a,

Chi/o^ei/ pints sinu(n<i('^ (llool,-.), Necs. — Robust, often 5

 triangular, 3 mm. long, dorsal base free, very decurrent or 

 slightly connate with opposite leaf, margin substrict un- 

 dulate, apex rather acute, ventral margin broadly curved 

 undulate entire ; cells 27 ^,, trigones large convex. Under- 

 leaves very broadly connate with the leaves, short, broadly 

 leniform armed with many irregular spines.
