its ventral side alone pubescent : all these species are very closely allied in structure, habit, and appearance, and rank 

 much more naturally as a genus of themselves, than as combined with Sarcomitrium. 



Gen. XXIX. SAECOMITEIUM, Corda. 



Frondes latinervse, sinuate, pinnatifidse vel bipinnatse. Involucrum laterale, breve, lacerum. Perian- 

 thium 0. Calyptra carnosula, elongata, subcylindrica. Anthem lobulis frondis propriis a tergo immersee. 

 — Aneura, Bumort. G. B. et N. Syn. Hep. p. 493. 



This genus contains all the Aneura, and part of the Metzgerice, of the ' Synopsis Hepaticarum,' where the fronds 

 have been described as nerveless, though consisting of very little beside nerve. In 8. pingue, and the wider-lobed 

 species, there is but a single row of cells on each side of the nerve, to represent the leafy tissue of the plants. Aneura 

 being therefore inapplicable, Sarcomitrium has been adopted as the better generic name. 



1 . Sarcomitrium altemilobum, Mitten ; fronde applanata vage ramosa, ramis alternatim obtuse lobatis 

 apice rotundatis crenatis, margine minute remoteque denticulato, calyptra setulosa. — Aneura alterniloba, 

 Loud. Town. Bot. 1844, p. 527. G. L. et N. Syn. Hep. p. 496.

Nigro-viride. Irons bipollicaris, vage ramosa, tenuis, prostata, apice rotundata crenulataque. Calyptra 

 setulis pallidis obtecta. Capsula lineari-oblonga ; pedunculo unciali. 



Distinct from S. pingue (Linn.) in its more regularly alternately lobed fronds, which have their margins re- 

 motely denticulate, and which appear to be of a thinner texture. 



2. Sarcomitrium palmatum, Mitten. — Jungermannia palmata, Hedw. Thor. Gen. ed. 1. t. 18./. 93-95. 

 Aneura palmata, Nees. G. L. et N. Syn. Hep. p. 498. 



Hab. Northern Island : dense Beech forests on the East Coast, Colenso. 



3. Sarcomitrium crassum, Mitten; fronde procumbente pinnatifida subopaca laciniis obtusis. — Junger- 

 mannia crassa, Schwmgrichen, Prodr.p. 31. Aneura crassa, Nees. G. L. et N. Syn. Hep. p. 500. 



Hab. Northern Island : dense forests on the East Coast and interior, Colenso. 



The specimens referred to this species are of a very rigid opaque texture, and of a brown or blackish-green 

 colour ; the stems are branched in a pinnate manner, and when dry the plants are almost horny. 



4. Sarcomitrium pinnatifldum, Mitten. — Aneura pinnatifida, Nees. G. L. et N. Syn. Hep. p. 495. 

 Hab. Middle Island : south extreme, By all. 



5. Sarcomitrium multifidum, Mitten.— Jungermannia multifida, Binn. Sp. PI. ed. 2. p. 1602. Hook. 

 Brit. Jung. t. 45. Aneura multifida, Bumort., G. B. et N. Syn. Hep. p. 496. Fl. Antarct. p. 167 et 444. 



Hab. Northern and Middle Islands : wet banks and watercourses, Bay of Islands, East Coast, and 

 interior, /. B. II. Port Cooper, By all, Colenso, etc. (A native of England.) 



These specimens differ in no particulars from European. This species is cosmopolitan, and found as far south 

 as Campbell's Island and Cape Horn. 



6. Sarcomitrium prehensile, Mitten. — Metzgeria prehensilis, Hooh. fil. et Tayl. Fl. Antarct. p. 445. 

 t. 160./. 9. G. B. el N. Syn. Hep. p. 505. 



Hab. Northern Island : dead wood, Manawatu river, Colenso. Port Nicholson, Byall. 



Originally found at Cape Horn. — This species has a pruinose appearance when dry, which is also observable in 

 the following, but it does not arise from any kind of pubescence.
