Plagiochila.'] 
V. HEPATIC/E. 
507 
form ; stems erect ; branches somewhat fascicled, 2-4 in. high. Leaves 
vertical, closely imbricate, subsecund, rhomboid-obovate ; dorsal margin quite 
entire ; ventral arched and the apex toothed. Perianth terminal, ovate, com- 
pressed; mouth toothed and ciliate. — Syn. Hep. 55. P. gregaria, Hook. f. 
and Tayl. in Lond. Journ. Bot. 1844, 564 ; Syn. Hep. 654. P. Iceta, Mitten. 
Northern and Middle Islands: common, on stumps of trees, etc., from the Bay of 
Islands, J. D. H, to Thomson Sound, Lyall. (Tasmania.) 
17. P. annotina, Lindb. ; — FI. N. Z. ii. 131. Stems stout, erect, 3-5 
in. high, dichotomous. Leaves very closely imbricate, dimidiate-ovate, con- 
vex, obtuse, toothed and ciliate ; ventral bases conniving and forming a crest. 
Perianth terminal and lateral, oblong, with a narrow toothed wing ; mouth 
truncate, compressed, fimbriate. — Syn. Hep. 41, 643. J. adiantoides, Hook. 
Muse. Exot. t. 90. 
Northern and Middle Islands: on trees; Tarawera, Colenso ; Dusky Bay , Menzies ; 
Otago, Hector and Buchanan ; Southern Island, Lyall. (Tasmania.) 
18. P. incurvicolla, Ilook. f. and Tayl.; — FI. N. Z. ii. 132. t. 96 ./. 
2. Stems suberect, 2 in. high, sparingly branched, flexuous; tips decurved. 
Leaves close-set, brown-green, rigid, spreading, ovate or obovate, coarsely 
spinous-toothed all round. Perianth narrow, oblong-clavate, compressed ; 
tips rounded, toothed. — Syn. Hep. 651. 
Northern and Middle Islands: Auckland, Sinclair; Wairarapa valley, Colenso; 
Milford Sound, etc., Lyall ; Otago, Hector and Buchanan. Allied to P.fasciculata, but 
not branched like that plant. 
19. P. Lyallii, Mitten in FI. N. Z. ii. 132. Steins erect, dichoto- 
mously and fastigiately branched, slender, flexuous, 2-3 in. high. Leaves 
brown-green, rather remote and rigid, broadly ovate or semicordate ; dorsal 
margin quite entire; ventral and apex spinous; involucral similar, more 
toothed. Perianth as in P. incurvicolla , from which it differs in the entire 
dorsal margin of the leaf. 
Northern and Middle Islands : Auckland, Sinclair; Port Preservation, Lyall. The 
description and figure of the perianth in the Flora of N. Z. represent it as too short and 
broad. This again most closely resembles P . fasciculata. (Tasmania.) 
20. P. Sinclair!!, Mitten in FI. N. Z. ii. 132. t. 96./. 5. Stems 4-5 
in. long, erect, strict, sparingly branched. Leaves loosely imbricate, olive- 
brown, divergent, obliquely ovate-oblong, obtuse ; dorsal margin retlexed, 
quite entire ; ventral and apex spinulose, lower orbicular. Perianth -g- in. 
long, terminal, oblong-ovate, compressed; mouth truncate, toothed. 
Northern Island : Auckland, Sinclair; Tehawera, Colenso; Port Nicholson, M ant ell. 
A noble species. 
4. LEIOSCYPHUS, Mitten. 
Stems prostrate, creeping or ascending; branches spreading. Leaves suc- 
cubous, spinulose, distichous, close set, entire, rarely 2-fid. Stipules small, 
2-4-fid. Fruit terminal. Involucral leaves like the cauline. Perianth di- 
lated upwards, compressed at right angles to the direction of the leaves ; 
mouth entire or toothed. Capsule on a slender fruitstalk. Antheridia as in 
Chiloscyphus.
