latos dein in lacinias duas divergentes articulatas fissas producta, ciliis interjectis vel nullis. Capsu/a ple- 
rumque spheerica, microstoma, exannulata, siccitate sulcata, inclinata, erecta, vel cernua. Opereulum plano-

§ 1. BARTRAMIDULA.— Capsula gymnostoma, estriata, in pedicello arcuato horizontalis vel pendula. 
Florescentia monoica. Plante parvule, tenella, sub apice fertili verticillato-ramulose. 
l. Bartramia pusilla (G/yphocarpa, Hook. fil. et Wils. Lond. Journ. Bot. 1844, p. 545); caule 
brevissimo gracillimo subramoso, foliis erecto-patentibus minutis ovatis acutiusculis laxe reticulatis subin- 
tegris margine planis evanidinerviis, perichætialibus brevibus erectis, seta apice arcuata brevi, capsula pen- 
dula globosa, operculo subconico planiusculo. (Tas. CLXXIV. Fig. 2.) 
Has. On rocks: near Hobarton, Lyall. 
Scarcely 2 lines in height, the very short stem growing from a creeping stolon. Branches few, subfasciculate, 
curved, slender. Leaves very small, pellucid, with a very faint nerve. Capsule reddish-brown, lined at the mouth 
with a faint annular membrane adherent to the apex of the columella, which closes the orifice. Spores yellow, 
rather large. Seta pale. Inflorescence synoicous and monoicous.—A smaller species than Bartramidula Wilsoni, 
Bryol. Europ., with leaves of both stem and perichætium one-third as small, without serratures. Capsule globose.

$ 2. PHILONOTIS.—Capsula peristomio instructa, striata, pachyderma. Caulis sub apice florifero fasciculato- 
ramosus.  Florescentia monoica et dioica; fl. masc. discoideus. 
2. Bartramia remotifolia (Hook. fil. et Wils.); dioica, caule humili gracili fasciculatim ramoso, 
ramis gracilibus brevibus subrecurvis, foliis glaucescentibus distantibus patentibus siccitate laxe crispatis 
lanceolato-acuminatis serrulatis margine planis nervo pellucido angusto excurrente, perichetialibus longio- 
ribus erectis, seta elongata crassiuscula, capsula suberecta.— Philonotis appressa, Mitten, in Journ. Linn. 
Soc. ined. (Tas. CLXXIV. Fig. 3.) 
Haz. Gullies Road, Brown's River, Oldfield. (Specimen very scanty and immature.) On rocks: 
Elliott Rivulet. Rivulet near Cumming's Head, Western Mountains, Archer. 
Stem 2 inch, very slender, not thicker than the fruit-stalk. Foliage pale, glaucous, with small, dense, opaque 
areole. Seta nearly 1 inch long, red.—Allied to B. glauca, Arnott ; habit more slender; leaves crisped when 
dry.—PrAvE CLXXIV. Fig. 3; 1, portion of stem and leaves; 2, leaf :—both magnified. 
This appears to me to be the fertile state of B. appressa, Fl. N. Zeal. ii. 89.— Mitten, in lit. 
3. Bartramia tenuis (Taylor, in Phytol. 1544, p. 1095); dioica, caule gracili apice fasciculatim 
ramoso, ramis gracilibus flexuosis, foliis laxis patentibus secundis anguste lanceolatis serrulatis margine 
planis nervo longe excurrente dorso spinuloso acuminatis, pericheetialibus sda acuminatis erectis, seta 
longiuscula gracili, capsula inclinata, peristomii interni processibus elongatis apice connexis, flore masculo 
capituliformi, foliis. perigonialibus apice patenti-incurvis longe acuminatis serrulatis. (Tas. CLXXIV.
