1913. 



D. suhsinuosum^ CM., is only a slightly more robust 

 form due to favourable conditions. 



Slopes of Mt. Wellington, West Coast, etc. 



Distichophyllum microcarpum (Hedw.). 



Livid green in mats or pendulous; stems flat, thick, 

 fleshy 3 cm., but on dripping rocks elongating to 15 cm. 

 Leaves oblong-obovate, very obtuse, 2-3 mm. more com- 

 planate than in the other species and not crisped when 

 dry ; margin plain unbordered, marked by collapsed cells 

 when dry; nerve vanishing above the middle, upper cells 

 12m Seta slender dark 1 cm. ; capsule inclined, ovate 

 with a thickened neck, 1 mm. ; lid conic, shorter than cap- 

 sule; calyptra rather long, rough, base torn not fimbriated. 

 Intermediate between Disticho'phyllum and Pterygophyl- 

 lum. 



Gehereb described a robust specimen as D. Levieri. 



Mt. Wellington, Ida Bay, Grass Tree Hill, etc. 



Pterygophyllum Brid. 



Decumbent or ascending, simple or with few vague 

 branches, of more tender consistency than most mosses, be- 

 coming very distorted when dry. Leaves in five rows or 

 fewer, all strongly complanate, the laterals patent, the dor- 

 sals and ventrals smaller and closely appressed or some- 

 times all nearly equal, broad, not bordered, margin den- 

 tate ; nerve short, forked ; cells large rotund to hexagonal, 

 larger towards the base. Seta smooth ; capsule usually 

 pendulous, oblong to pyriform ; lid with a long rostrum ; 

 calyptra constricted at the base, plain, often irregularly 

 split. Peristome typical. 



The species are variable and the division is arbitrary. 



Robust. Lateral leaves 5 mm. or more HooJceri. 



Less robust. Lateral leaves smaller. 



Cells hexagonal denticulatum. 



Cells rotund nigellum. 



Pteryr/ophyllum Hoolceri Jaeg. 



Robust, stems fleshy, flat, often 5 cm. dark green. Lateral 

 leaves oblong-obovate, of thin texture, 5 mm., margin 

 coarsely toothed ; nerve rather bold brown, forked, vanish- 

 ing above the middle ; cells hexagonal about ^^p-. Seta 8-5 

 cm., capsule inclined or pendulous, oblong or pyriform 

 with a rather abrupt neck 1.5 mm. ; lid as long as the cap- 

 sule ; calyptra longer, in'egularly torn at the base. 



Common in damp gullies.
