EcHiNODiuM Jur 



Habit elongated, simple, or with few branches, flaccid. 

 Leaves plurifarious, linear-lanceolate or filiform, rather 

 long, the greater length made up of the broad excurrent 

 nerve ; cells small, irregularly rotundo-quadrate, smooth, 

 rather incrassate. Seta medium length, smooth, curved 

 above; capsule short; broadly oblong, inclined, equal; lid 

 rostrate; exostome teeth lanceolate, slender, bordered by 

 a thin membrane ; endostome membrane half as deep as 

 the exostome, processes lanceolate, perforated, two or three 

 irregular cilia between each pair. 



The genus may be quite as well referred to Hypnoceae, 

 but its affinity to Cyrtnpua justifies its position in this 

 family. 



EchinodiuDi hispidum (H.f. et W.) Jur. 

 Syn : Hypnum hispidiim, H.f. et W. 



Branches long, often 15 cm., sometimes with slender 

 flagellate tips, dark green, flaccid, simple or nearly so. 

 Leaves patent, filiform from a broader base, 4.5 mm., mar- 

 gin plain, nerve flat, broad, forming the upper two-thirds 

 of the leaf. Seta 1.5 cm. ; capsule very broad, 1.8 mm. 



Very common on banks of streams in shady mountain 

 slopes. 



Cyrtopus Hook. 



Rather robust, erect from a creeping rhizome usually 

 with a few irregular branches above. Leaves close set, the 

 base short, oblong, erect, then very slender recurved to a 

 filiform apex; margin plain below, spinulose above; nerve 

 slender, excurrent; cells oblong to fusiform, strongly in- 

 crassate. Fertile branches very short, lateral. Seta slen- 

 der short ; capsule erect, oblong ; calyptra short cucullate ; 

 lid obliquely conic-rostrate; peristome double, erect; exos- 

 tome teeth narrow lanceolate; endostome membrane short, 

 processes subulate rather shorter than the exostome. 



Cyrtopus setosus (Hedw.) Hook. 



Often 5-8 cm. Leaves 5 mm. ; perichaetials not differ- 

 ing. Seta 4 mm. ; capsule narrow oblong 2 mm. 



Reported from Tasmania but no Tasmanian specimen in 

 the collections. Very possibly an error. 



Thamnium Sehimp. 

 Erect or suberect, dendroid from a creeping rhizome, 

 irregularly branched from the base. Leaves complanate, 

 ovate ; nerve single, flat, lost above the middle ; cells ovate-
