410 NEW HEPATICiE. 



these series indifferently into several valves or pieces of un- 

 equal breadth ; all, however, united at their summits. 

 4. S. pulchra, Tayl. ; fronde implexa, procumbente, sub- 

 stipitata, subsimplici, lineari-elliptica, apice biloba, integer- 

 rima, roargine flexuosa; perigoniis alternating supra nervurn 

 confertis ; calyptris epiphyllis, linearibus, apice pistilliferis, 

 basi squama tubulosa subdentata tectis. 

 Hab. Swan River. Mr. James Drummond. 



Fronds pale green, scarcely 1 inch long, largely and dis- 

 tinctly cellulose. The tops of the nerves send down rootlets, 

 and send forth buds, which at first appear to consist solely 

 of a nerve, but which as it elongates assumes &pagina at each 

 side. Peduncles 4-5 lines long. Anthers sphserical, whitish, 

 pedicellated. The tubular, subterminal calycine scales dis- 

 tinguish this from the preceding, as well as from the other 

 Symphyogyna. 



22. Metzgeria, Nees. 



1. M. algoides, Tayl. ; fronde erecta, compressa, gracili, bi- 

 tripinnata, pinnis deflexis, pinnulis anguste linearibus, 

 acuminatis, integerrimis, uninerviis ; calyptris fasciculatis, 

 axillaribus, oblongo-obovatis, apiculatis, scabridis, basi 

 squamis aggregatis linearibus tectis.

 Prof. W. Jameson. Hook. Herb. 



Fronds aggregate, 5-6 inches high, very slender, olive- 

 coloured ; branches alternate ; margins of the pinnules entire. 

 Two, three, or more calyptree are collected about the upper 

 parts of the fronds. Calyptree thick and tough. Barren in- 

 dusia are scattered over different parts of the frond. The 

 branches are far more elongated and more deflexed than either 

 in Jung.fucoides, Hook, or in Jung, ericoides, Hook, and the 

 calyptree are more clustered than in the latter. 



23. Fegatella, Tayl. 

 1. F. microcepfiala, Tayl. ; fronde minuta, canaliculata, dicho- 

 toma, sinu ampliori ; pedunculis elongatis ; receptacuHs
