112 TASMANIAN BRYOPHYTA., 



surface obtusely furcate papillose, lower cells larger, colour- 

 less. Seta short, capsule erect, oblong, with a short, taper- 

 ing base, smooth, but when dry marked at least in the 

 upper portion with 8 grooves; lid conic to shortly ros- 

 trate; calyptra with a long campanulate base enclosing 

 the capsule, sparely clothed with erect hairs; peristome 

 double, exostome of 8 geminate, short, teeth usually sharp- 

 ly recurved when dry ; endostome of 8 erect short, obtuse 

 cilia. 



Differing from Ulota only in a small difference in the 

 arrangement of the leaf cells. In Europe the seta is con- 

 sistently very shoai:, while in Ulota it is long, giving the 

 plants an apparent distinction. The stomata and vaginule 

 do not assist us, and are not referred to. 



Seta much longer than capsule. 



Capsule cylindric with a slender base...tasmanicum. 



Capsule broader with a broad base laticiliatum. 



Seta shorter than the capsule Lawrencii. 



ORTHOTRICHUM TASMANICUM, H.f . et W. 



Stems about 1 cm., yellow green, covered with pur- 

 plish radicles below. Leaves lanceolate, patent, little or 

 Ht)t at all crisped when dry. acute, undulate, 3 m-m. ; mar- 

 gin revolutei; nerve lost below the apex; cells rotund, 

 strongly incrassate, each with a short forked papilla, low- 

 er ones irregularly broadly linear. Seta 5 m.m. ; capsule 

 oblong-cylindric, tapering at the base, deeply grooved when 

 dry, 2 m.m. ; lid conic or with a short slender rostrum ; 

 calyptra shining, bearing few hairs, very acute and dark 

 at the apex ; peristome teeth obtuse ; endostome teeth 

 s-horter, broad. 



Common on trees and shrubs on slopes of Mt. Welling- 

 ton, etc. 



ORTHOTRICHUM LATICILIATUM, Vent. 



Very close to O. tasmanicum, only rather more ro- 

 bust. Leaves lanceolate, acute, 3.5 m.m. Capsule groov- 

 ed above, the lower part smooth, broader, with a rather 

 abrupt base. Other details as in O. tasmanicum. 



Slopes of Mt. Wellington. Forth River Gorge.
