BRYOPHYTE NOTES. 



By W. a. Weymouth and L. Rodway, C.M.G. 



(Read 10th October, 1921.) 



In the description of the Mosses of Tasmania recorded in 

 Papers and Proceedings for 1913, a specimen of Ephemerum 

 cristatum, H.f.W., not being available, Mitten's description 

 was used. This is vague and insufficient to assist the junior 

 student. The plant is minute, barely one millimetre in 

 height, the capsule is globose as in Acaulon, but the leaves 

 are very distinct. These are of thin texture, ovate-acuminate, 

 the margin and midrib armed with relatively long simple or 

 compound spinous processes. The cells are rectangular, but 

 very irregular in size and shape. This description is from 

 a specimen gathered at Bellerive by A. J. Taylor in 1886. 



Mitten described a plant and named it Trematodon 

 flexipes. It was gathered at Cuming's Head, Western Moun- 

 tains. For some reason Dr. Brotherus, in Pflanzenfamilien, 

 refers it to Campylopodium as Ccunpylo podium flexipes 

 {Mitt.) Broth., though it has the typical arcuate capsule with 

 a long apophysis .of Trematodon.. The plant described under 

 Brotherus' name in the description of Tasmanian Mosses 

 above referred to, is Campylopodium euphorocladiuin (CM.), 

 Besch. The true Trematodon flexipes, Mitt., does not appear 

 there at all. Mitten's plant is: — Small, subulate, entire 

 leaves, wich a broad nerve occupying the upper three-fourths 

 of the leaf, margin entire. Seta about 5 mm., flexuose; capsule 

 inclined, oblong, 1 mm., with a long slender apophysis; lid 

 with an inclined slender beak slightly longer ; calyptra dimidi- 

 ate, inflated. Peristome with deeply cleft teeth. 



The following are new to Tasmania, and determined by 

 H. W. Dixon:— 



Trematodon machayi (R. Br. Ter.) , Dixon. Stem 2-3 mm. 

 Leaves with a broad sheathing base and a long subulate 

 lamina 4 mm. Seta straight, 10 mm. Capsule narrow ob- 

 long, inclined to arcuate, 2 mm., tapering into a slender 

 apophysis 3 mm., lid with a slender rostrum 1 mm. Peri- 

 stome, none. 



West Coast. T. B. Moore. Also New Zealand. 



Pottia heimii (Hediv.), Feurn. Small, erect, 6-10 mm. 

 Leaves narrow-ovate, acuminate, acute, 2 mm., with a few 

 serrations towards the apex; nerve slender, continuous, or
