902 SOME ADDITIONS TO THE MOSS FLORA OF TASMANIA. 
Annulus simple, persistent. Teeth 8, closely reflexed when 
dry, in double pairs, 24 micromill. long, obtuse, apex 
not free, not lacunose but sparingly perforate, joints 
dense, short, and very minutely papillose. Cilia 8, of equal 
length, thread-like, smooth. Calyptra yellow,  strigose, 
densely pilose, the hairs being thick, rather rough, and of 4—5 
series of cells. Spores minuutely papillose, 50 —35 micromill. 
in diameter. 
Hab. Mount Wellington, on trees, 1891, W. A. Weymouth, 
No. 900. 
4. Ulota viridis, Vent., n. sp. 
Monoicous. Tufts depressed, green; stem creeping; 
branches scarcely 1 cm. high, erect. Leaves scarcely curved 
when dry, from an ovate concave base gradually linear-acu- 
minate, acute, 15 mm. long. Areolation above by gently 
projecting cells, without papille; below at margin with 7—9 
series of transparent and quadrate cells, forming a border; 
the middle part consisting of narrow, fuscoid cells, with very 
broad walls tinged with red. Perichetial bracts from a 
rather long base red, larger, 2 mm. long. Vaginula 
sparingly pilose, ovate. Seta 1:'5—1:75 mm. long. Capsule 
pyriform, with tapering neck of equal length, 2 mm. long; 
when dry furrowed to the middle and beyond. Striz short, 
scarcely a third of the sporangium long, consisting of 2—3 
series of cells. Stomata emersed, dispersed in the neck. 
Teeth 8, reflexed when dry, in double pairs, apex entire and 
obtuse, minutely papillose, jointed. Cilia 8, of equal length, 
threadlike, smooth. Spores minutely papillose-aculeate, 23—25 
micromill. in diameter. Calyptra conic-bell-shaped, scarcely 
covering half the capsule, divided at the base, pilose with 
yellow hairs consisting of two, rarely three, series of cells. 
Hab.—Mount Wellington, on trees, Oct., 1890, W. A. 
Weymouth, No. 901. 
This plant is very near to U. Ludwiqit. 
5. Orthotrichum lateciliatum, Vent., n. sp. 
Monoicous. In tumescent tufts; stems erect, 2 cm. high. 
Leaves curved and laxly crisp when dry, erecto-patent when 
wet, from an ovate base long lanceolate, keeled, 3°33 mm. 
long, apex more or less acuminate, margin recurved up to 
apex, nerve lost in apex. Areolation above by round hexa- 
gonal cells, walls not incrassate, papillae prominent, simple or 
two-pronged; below elongated, narrow cells, with walls not 
incrassate, complete the base. Inner perichetial bracts 
rather small, with flat margin. Inflorescence lateral ; 
male gemmule small, antheridia few, ovate-oblong, 
stalked, without paraphyses. Vaginula cylindric, sparingly 
pilose, with a distinct ochrea adhering to the seta. 
Seta 3:20 mm. long, twisted when dry. Capsule with short
