Caspites lati, 2 unc. diametro, pallide virides, iutricati. Caules vix -±- unc. longi, decumbentes v. prostrati, apicibus ascendentibus. Folia remotiuscula, margine superiore sursum gibboso; substantia dense cellulosa.
Closely allied to tbe /. discedens, Nees, of the East Indies ; but the leaves are shorter, wider, have a deeper sinus and more acute segments ; and the stipules are not so slender.

56. Jungermannia trachyopa, Hook. til. et Tayl. ; parvula, caule implex e ramoso procumbente flaccido, foliis tenerrimis laxe cellulosis imbricatis erectis subsquarrosis latissime rotundato-quadratis profunde bi-trifidis grosse iusequaliter spinidoso-dentatis, stipulis late ovatis bifidis segmeutis acuininatis grosse dentatis, calyce terminab oblongo trigono, ore laeiniato-dentato.

Hab. Hermite Island, Cape Horn; growing in the woods on Anthoceros punctatus, L.
Caules vix unc. longi, irregulariter ramosi, pallide virides. Folia arete imbricata, in lacinias duas v. plerumque plures lanceolato-subulatas divisa. Calyx pro planta majusoulus. Capsula ovalis. Seta cauli sequilonga. A very distinct species from any of the foregoing, and a beautiful object under the microscope from the delicacy and reticulation of its leaves.

57. Jungerjiannia iriacantlia, Hook. til. et Tayl. ; caule implexo procumbente vage ramoso, foliis planis approximatis patentibus oblongo-ovatis trifidis segmeutis subulato-lanceolatis, stipulis subquadratis bifidis segmentis bilaciniatis laciuiis subulatis. Nobis in Loud. Town, Bot. vol. v. p. 368.
Hab. Falkland Islands ; on the ground.
Caspites densi, luride olivacei. Caulis uncialis, ramis paucis patentibus. Folia basi vix imbricata, patentia, divaricata, oblonga, apices versus sinubus duobus excisis aucta ; lacmiis 3 subidatis, porrectis, subparallehs. Stipules libera?, ereeto-patentes, quadrifidse, segmentis subulatis.
Most nearly allied to L. cldoropliylla, nobis, of New Zealand, which is, however, a smaller plant and has shorter wider subsecund leaves, and rounded dentate stipules, (7. Chiloscyphus, Nees.)
58. Jtjngekmannia pallido-virens, Hook. fil. et Tayl. ; majuscida, caule implexe subramoso procum-bente, foliis patentibus imbricatis late ovato-oblongis apice retusis integerrimis margine anteriore recurvo, stipulis miuutis recurvis oblongis bifidis segmentis subulatis extus unidentatis quadrifidisve, calyce in ramo abbreviato termiuali oblongo tri-alato compresso apice laciniato-ciliato. Nobis in Bond. Joum. Bot. vol. iii, p. 473. (Tab. CLIX. Fig. IX.)
Hab. Hermite Island, Cape Horn; on the ground near the sea.
Caspites late extensi, pallide flavo-virescentes, demum fuscescentes, interdum (status minor) omnino fuscati. Caules 2 unc. longi, parce ramosi, ramis unc. latis. Folia dense reticulata, areolis minutis, laxe imbricata, erecto-patentia, ope stipute basi connexa, apiee rotundata seu trimcata, unidentata v. emarginata. Stipules minima?, caulis y latitudine, concavee, recurvse, oblonga;; segmentis setaceis extus unidentatis. Perichatium ramum abbreviatum terminans, e paribus 2-3 foliolorum erectorum appressorum constans, foliolo interiore 4-5-partito. Calyx oblongo-
campanulatus, latere uuico profunde fissus.
