The mosses of Tasmania have had a very fair amount 

 of attention paid to them, so that it is improbable any 

 large number of new species will in future be added. The 

 Hepatics have not been neglected, but their variability and 

 the exceptional richness of form found in Tasmania have 

 made their study more obscure. No doubt in the future 

 many new species will yet be discovered, also some which 

 we now recognise will be suppressed. Still, we can safely 

 say that the hepatic flora of Tasmania approaches three 

 hundred, which means it is almost the richest in species 

 of any locality in the world. 



Of the following mosses the Andreaeas would by some 

 collectors be clubbed with A. petropliila, but then they 

 would have to be treated as varieties. A. petrophila is 

 most variable, and it is certainly desirable that prominence 

 should be given tO' the principal forms. Blindid acuta 

 was recorded as Tasmanian by J. D. Hooker. It is a 

 European species, and as no specimen was present in any 

 available collection it was left out of the previous work. 

 The Tasmanian form differs from the type, its leaf mar- 

 gin being quite entire, and the absence of quadrate cells 

 at the basal angles. It may yet be described as a dis- 

 tinct suecies. 



Andreaea asperula, Mitt. — Stems slender often to 5 

 cm., with few erect branches, forming dense red-brown 

 mats. Leaves narrow lanceolate, very acute, slightly in- 

 curved, 1 m.m. long, insertion narrow, not at all stem- 

 clasping nor geniculate, surface asperate, papilhe often 

 very large, margin incurved. 



A member of the petrophila group, it differs from 

 A. petrojjliila and A. tenera in the asperate cuticle and the 

 narrower leaf bases. 



Western Tiers, Eastern Australia. 



Andreaea taHmanica, n.s. — Stems slender, about 1 cm., 

 -crowded in dense mats, dark brown, upper leaves linear 

 from a slightly broadened base, strongly falcate and secund, 

 0.8 m.m. long, margin involute, apex acute, surface nearly 

 smooth, nerveless. Lower leaves and those of young 

 ishoots minute, closely appressed, very broadly oblong, with
