vanishing below the apex. Seta slender, erect, 12 mm. ; capsule 

 erect, oblong, 1 mm., peristone none, mouth broad; lid with a 

 slender rostrum. 



Locality unrecorded. W.A.W. 



Differing from P. subphyscomitrioides, chiefly in the ser- 

 rate margin and non-excurrent nerve. Range, cosmopolitan. 



Pottia mclhourniana, Dixon. Small, seldom exceeding 2 

 mm. Leaves oblong-spathulate obtuse, but apiculate, margin 

 entire but closely revolute below, nerve bold, dissolved in the 

 apiculate apex. Seta erect, 3-4 mm.; capsule broadly oblong, 

 with a wide mouth barely 1 mrn., lid with an oblique rostrum. 



Glenorchy. W.A.W. Also Victoria. 



Ditrichum punctulatum, Mitt. Slender, in dense 

 cushions, about 2 cm. long. Leaves narrow linear-subulate 

 from a long, narrov/, sheathing base, 5 mm., acutely serrate 

 towards the apex, nerve broad, cells oblong, shining and 

 twisting when dry. Seta 1.5 cm., capsule erect, narrow 

 cylindric, 2 mm., mouth constricted. Peristome teeth short, 

 slender, unequal. "In D. elongatum the leaves are dull and 

 "little twisted, otherwise they scarcely differ at all. But the 

 "fruit is different" (Dixon).

Milium rostratnvi, Schrad. In loose, dark green trailing 

 tufts with short erect fertile stems. Leaves shortly de- 

 current, broadly obovate, those of the coma spathulate 

 (Braithwaite). Margin limbate generally serrate above, 

 nerve continuous into a short apiculus or lost just below the 

 apex. Seta long, slender, capsule pendulous, elliptic, 2.5
