Hab. Lord Auckland's group ; on the ground, near the tops of the hills.

Caspites 2-3 unc. lati, pallide flavo-olivacei. Caides vix unciales, intertexti, vage rainosi, prostrati, apieibus ascendentibus. Folia fere reniformia, e marginibus valde incurvis concava, subpellucida, areolis niiiiutis. Stipulee parvae, sinu brevi, segrnentis subacutis. Calyx in rarao anni praeteriti terminalis, compressus, oblongus, basi angustatus, vix curvatus.

The leaves on the fertile shoots of this species rapidly increase in size upwards, becoming more densely imbricated; the terminal pair or perichsetial leaves are the largest and most erect.

Those species of Jungermannia with round, concave, imbricating leaves and bifid stipules, which inhabit the north of Europe, have their calyces subeylindrical or ovate; the present differs from all of them in that organ being decidedly compressed and truncate, appearing like a flattened cylinder after the egress of the capside. It may by some be considered as forming a separate genus, to which perhaps our /. strongylophylla should be referred. Plate LXIV. Fig. II. — 1, a specimen of the natural size ; 2, back view of stem, leaves, and stipules ; 3, front view of leaf and stipide ; 4, back view of leaf; 5, stipule; 6, calyx; magnified.

Hab. Lord Auckland's group ; on banks, in the woods near the sea, for min g large patches.

Caspites majusculi. Caides graciles, teretes, superne subincrassati et incurvi, pallide straminei, flaccidi, 2 unc. longi. Folia densissime imbricata, marginibus valde incurvis, quasi inflata, substantia molli, tlaccida, subpellucida, subauriculiformia, obbqua, antice decurrentia, carnosa. Stipulee valde concavee, lata;, pleruinque integrae, magnitudine 4- fobonun.

This curious and fine species is of a peculiarly flaccid and as it were greasy texture when moist; there is no European or exotic Juiigermannicl known to us with which it can be at all compared.

Jungermannia ei/mlalifera, Hook. fil. et Tayl.; caule laxe implexo suberecto v. procumbente subsimplici tereti curvato, foliis arete denseque irnbricatis erecto-patentibus oblique rotundatis serrulatis concavis margine anteriore sursuni in appendiculain obovato-rotundatam producto, stipulis transversis latissimis arete irnbricatis obscure trilobis integerrimis, calyce laterali ovato-oblongo subcomprcsso plicato ore dentato. (Tab. LXIV. Fig. V.)

Hab. Lord Auckland's group ; on the roots of old trees in the woods, rare.

Caspites laxi, pallide virescentes v. lutescentes. Caides subimciales, teretes, intertexti, simplices v. parce ramosi, flexuosi, prostrati, apieibus ssspius incurvis. Folia densissime imbricata, subsecunda, marginibus anticis approximatis, appendicibus seu auricnlis pedicellatis e membrana duplici formatis instructa, substantia subcarnosa, flaccida, pellucida, cellulis cbstinctis. Calyx vere lateralis, basi subtumidus, infra orem compressus, longitudinaliter plicatus, foliis perichaetialibus paucis.

A singularly beautiful and easily recognised plant, with much the habit and external appearance of /. notophylla, nobis, but most distinct from it and from any other species. The appendages of the leaves and the broad obscurely lobed stipules all closely imbricating up the stem give the appearance of a very complicated structure. Like the
