EPHEMEllUM Hampc. 



Minute and simple, arising from a peristent, byssoid, 

 protonema. Leaves few, lanceolate ; cells rhomboid, large 

 and colourless. Capsule immersed in the leaves, globose, 

 apiculate ; calyptra thin, campanulate, cleft or lacerate at 

 the base. 



Microscopic, short-lived mosses, growing from a per- 

 sistent alga-like protonema. Easily overlooked. There 

 may be more than the one species in Tasmania. 



EPHEMERUM CRISTATUM, H.f.W. 



"Monoious, very small, upon the filiform protonema. 

 Leaves spathulate or lanceolate, acuminate, incised dentate, 

 dentate on the nerve. Capsule immersed, subsessile, ovate- 

 globose with an acute apiculus ; calyptra campanulate, red- 

 brown. " Mitten. 

 Cheshunt, 



Absent from all available collections. 



ACAULON C. Muell. 



Minute, gemmiform. Leaves in three rows, the upper 

 ones largest, concave connivent ; cells large rhomboid. 

 Capsule nearly sessile, enclosed in the leaves, globose, not 

 apiculate ; calyptra very small, conic. 



ACAULON APICULATUM, H.f.W. 



Minute, yellow, the whole plant under 2 m.m. Leaves 

 few, very broadly ovate, apiculate, serrate, nerve continu- 

 ous. Capsule red, 0.3 m.m.. nearly sessile within the 

 leaves, globose. 



Cheshunt, Bellerive, Domain. Hobart, etc. Fairly 

 common on retentive soil ; vanishing at the end of spring. 



PHASCUM (L.) Schreb. 



Very small, tufted, gregarious. Leaves ovate or lanceo 

 late, entire, cells rhomboid-hexagonal, usually papillose. 

 Capsule subglobose or ovate, obliquely apiculate, without 

 a lid or mouth, on a very short seta, and usually immersed 

 in the leaves.
