36 CRYPTOGAMIA ANTARCTICA. | Auckland and 
12. JUNGERMANNIA hemicardia, Hook. fil. et Tayl.; caule ascendente subtriangulari simplici v. ramoso, 
foliis dense arcteque imbricatis erecto-patentibus oblique et late ovatis basi cordatis apicibus rotundatis mar- 
ginibus integris v. superne denticulatis subconcavis, margine anteriore recurvo posteriore basi in lobulum 
producto. (Tas. LXIII. Fig. IL.) 
Has. Campbell's Island; on exposed rocks, near the summits of the hills. 
Cespites fusco-olivacei, 1-2 unc. lati. Caules una cum foliis triangulares, $—1 unc. longi, e rhizomate repente 
ascendentes, simpliciusculi, rigidi, antice plani, profunde canaliculati. ` Folia arcte imbricata, integra v. denticulata, 
opaca, dense cellulosa, areolis minimis hexagonis. 
The leaves of this species meet back to back and are so closely imbricated that the stems appear triangular, 
their anterior margins not touching but leaving a space which appears like a groove running down the whole length 
of the stems, their recurved margins are rather tumid and decussate on the opposite face. In general habit this 
resembles the J. punctata, Tayl., a species recently detected both in Ireland and the Canary Islands, from which the 
gibbous or oblique leaves will readily distinguish it.

Has. Lord Auckland’s group; on rocks and on the hills, rare. 
This agrees with authentic specimens of Lehmann’s plant, except in the summits of the stems not being so re- 
markably circinnate as they are described. Such circinnate summits, however, are truly. perigonia, whose leaves are 
smaller, more ventricose and erect than those of the stem; and further, some of them contain in their axille a single, 
rather large, pedicellated anther. Our specimens are about half an inch long, stout and curved; the leaves much 
more lax than in the former species. 
14. JUNGERMANNIA cognata, Hook. fil. et Tayl.; parvula, fulva, caule erecto ceespitoso subsimplici v. 
ramoso, foliis laxe imbricatis patulis late ovatis v. elliptico-oblongis acuminatis paucidentatis basi attenuatis 
decurrentibus, margine anteriore vix recurvo, calyce terminali perichztio «equilongo vix curvato bilabiato 
labiis ciliato-dentatis. (Tas. LXIII. Fig. III.) 
Has. Lord Auckland's group; on alpine rocks, growing amongst stunted tufts of Hymenophyllum 
multifidum. 
Cespites diametro 1-2 unciales, inferne brunnei, superne flavi v. flavo-fusci. Caules erecti, 1 unc. longi, subri- 
gidi, inferne nudi, parce ramosi, anni præcedentis sæpius innovati, apicibus subcurvatis. Folia disticha, subpatentia 
v. divaricata, coriacea, apices versus 3—5 dentata, dente apicali majusculo acuminato, margine anteriore subrecurvo 
decurrente; folia perichætii erecta, elongata, magis dentata. 
This has much affinity to the J. decipiens, Hook., a very variable species in the form of the leaves, but in which 
their cellules are much larger and more lax, while in this they are so dense as to be hardly distinguishable. The 
European plant differs further from the present in a character alluded to by the authors of the * Synopsis Hepati- 
carum, who remark, ** J. decipiens ab omnibus congeneribus margine dorsali folii inflexo nec reflexo differt."
