446 91. Jungermannia confluent, Tayl. in Lond.Joicm. Hot. vol.iii. p.478. (Tab.CLXI. Fig.VII.in part.)

Hab. Hermite Island, Cape Horn ; on the bare ground in woods. Falkland Islands and Christmas Harbour, Kerguelen's Land ; on moist banks.

Laxe casspitosa. Frondes flaecidissiuii, 2 una longi, erecti. Caulis simpliciusculus, foliis imbricatis oinnino occlusus, subrufescens, gracilis. Folia alteima, tenerrima, madore carnosiuscula, siccitate membranacea, aegre resus-citentia, et inter se quasi confluentia (hinc irons prima visu contiuua et lobata), basi latissima, bis latiora quam longa, longe decurrentia, fere arnplexicaulia, semi-orbicularia, apice rotundata v. retusa, areolis majusculis. Involucrum terminale, sessile, erectum, cylindraceum, compressum, ore eroso-dentato. Seta uncialis, gracilis. Capsula ovato-globosa, irregulariter v. regulariter rurnpens. Elateres brevissimi. Cahjptra irregulariter rupta, parte superiore stylo persistente terrninata. A/d/iera ovato-oblonga?, biseriales, substantia frondis immersas, liquido oleaginoso scatentes.

A genus allied to Fossombrouia, but the structure of the involucre, apparently formed very much out of the frond itself, is quite dissimilar. The involucre is terminal in this species, but lateral in a Brazilian congener, which was long regarded as identical, and smooth; when terminal, winged from the adhesion to its surface of the upper abbreviated leaves: it is either truncated or obscurely two-lipped. The young spores are united by fours in a transparent membrane. The drawing of the fruit is taken from Brazilian specimens of an allied species, or perhaps variety, collected by Mr. Gardner ; the leaves of the Antarctic plant having become so firmly united under pressure, that no maceration would separate them satisfactorily.

In the 'Synopsis Hepaticarum' of Nees, Lindenberg and Gottsche, the generic name has been changed to Androcryphia, with the following explanation. "Noteroclada nomen Greece cum sonet neque Grseci esse possit originis, (soil, vwtos tergum non dat varepov, neque ^XaSou sive rami character hoc loco succurrit); substituere aliud nomen a?gre id quidem mecum sustinui." (J. c. p. 470.) The derivation of the name being, however, vorrfpbs "madidus," sufficiently vindicates the adoption of Noteroclada.

Plate CLXI. Fig. VII. (in part.) — 1, Brazilian, and 2, Falkland Island specimen, of the natural size ; 3, branch, leaves, &c, of the Brazilian specimen ; 4, leaf of ditto ; 5, corolla of ditto : — magnified.

(18. Fossohbronia, Nees.)

92. Jungermannia ^«i#«, L.

Hab. Kerguelen's Land ; on banks amongst moss, &c.

Also a native of New Zealand, and probably not an uncommon plant in the temperate parts of the Southern as it is of the Northern hemisphere.

2. MARCH ANTIA, March.

1. Mahchantia polymorpAa, L. Flor. Antarct. Pt. 1. p. 168. Hab. Fuegia, the Falkland Islands, and Kerguelen's Land; very abundant.

This is perhaps the most widely dispersed of Hepatica, ranging from the Arctic circle to the 57th degree of south latitude.

3. ANTHOCEROS, Michel.

1. Anthoceros punc tatus, L.

Hab. Hermite Island, Cape Horn, and the Falkland Islands ; very common.
