136 TA,SMA]SIAN BRYOPHYTA, 



FISSIDENS BREVIFOLIUS, Hf. et W. 



Small, green, seldom exceeding o m.m. Leaves gen- 

 erally 7-10 pairs, erecto-patent, oblong-, straight, apiculate, 

 with a narrow border from only on the lower part of the 

 sheath to extending partly up th& lamina, 0.7 m.m. long, 

 the sheath usiually | the length; nerve bold, vanishing 

 abruptly in the apex ; margin rather cremate ; cells irret- 

 gular in size and shape, roughly quadrate, rather thin 

 walled, 6-10 u. Seta very slender; capsule oblong, erect to 

 much curved, 0.7 m.m.; lid broadly conic; calyptra short, 

 broad, spliit on one side. 



Forms with the border excessively developed may be 

 distinguished from small forms of F. leptocladus by the 

 larger, leas incrassate cells. 



Slopes of Mt. Wellington. 



FISSIDENS VITTATUS, Hf. et W. 



Small, slender, usually about 5 m.m., yellowish, apex 

 recurved Leaves about 10 pairs, rigid, opaque, generally 

 imbricate, ovate, oblong, apiculate, recurved, 1.3 m.m., the 

 surface papillose ; margin limbate, on the sheath the 

 limb is broad, and within the margia below, elsewhere 

 narrow, hyaline, or absent; margin obscurely serrate; nerve 

 lost in the apex, to shortly excurrent; cells regular, rotund, 

 very convex, 7 u. Seta slender, 1 cm., capsule erect, nar- 

 row-oblong, 0.7 m.m. ; lid with a slender rostrum about half 

 as long. 



Slopes of Mt. Wellington, Strickland, Circular 

 Head, etc. 



FISSIDENS LEPTOCLADUS, CM. 



Stems slender, mostly 1-1.5 cm. Leaves smooth, 

 numerous, straight, revolute when dry, ligulate to oblong, 

 with an acuminate, rather acute, apex, 1.3 m.m., limbate, 

 the border narrow, lost in the apex, and at the dorsal base, 

 very broad at the base of the sheath, but variable, some- 

 times broader and coalescing, with the nerve in the apex ; 

 nerve rather broad, usually lost in the apex ; cells irregular- 

 ly quadrate, not incrassate, 5-6 u., sometimes nearlv ro-
