tliose gathered by Mr. Gunn, but they are not obvious ou all the stems, and are thus easily overlooked. The involucral
leaves scarcely differ in form from the cauline, but are concave, nnd enclose fom or five pistils, seated on the
dorsal side of the abrupt and slightly thickened apex of the stem itself ; «ithin the involucre there has bccu observed a
small stipule-like leaflet, but uot appai-eutly representing the stipule, wliich, although present, has no part in the formation
of the torus in the plants of this and aUied genera.— P la t e CLXXIX. Fig. 4 ; 1, a ])ortion of the stem, with

Caulis in plantis fertiiibus brevis, semiimcialis. Torus ex apice caulis areuali deseendens, brevis, cyliudi'icus, Go-
laceus, radicellis parvis obtectus. Folia superiova magis lacero-dentata. Amphigastria superiore canlinis confonnia,
usque ad medium fere tori protraetis, ulteriora violácea.
The fertile plauts of this most curious species were gathered in New Zealand by Mr. KeiT, and thus is set at
rest the before very doubtful place of the present and of 0. erinacea {Jungerimnnid), Hook. fil. et Tayl. Fl. Antarct.
pi. 161. f. 4. Indeed the whole appearance of the barren plants of both species is so different from that of G. saccata,
that n-ithout fertile specimens their affinity with Gymnanthe could hardly have been expected. The toras appears to
agree in all particulars with that of 0. saccata, and on the under side, that is to say, on the side next to the stem,
the amphigastria are continued, the lower oue having the same violet colour as the torus itself.—P l a t e CLXXIX.

6. Gjrmnanthe concinna (Mitten) ; caule repente ramoso, foliis imbricatis oblongo-ovatis concavis
apice rotundatis sursum conniventibus vel parum explanatis, involucralibus majoribus conformibus vel apice
retusis, toro . . . (T ab . CLXXIX. Eig. 6 .)
H a b . Tasmania, Gunn, creeping over Jungermannia Tasmanica, Tayl.
Pallide iTiidis. Caulis 8- 8-linearis, hie illic radiculosus, apice fructifère descendente. Folia apicem versus sensim
majora, iuvoluCTalia convoluta. Torus juvenilis (apex caulis incrassatus) archegoniis 5-6 proeditus.
A very small species, of a very neat habit, aud with somewhat the look of the stems of some states of the European
Jungermannia nana, Nees. The apex of the stem is slightly thickened, and curved doivnwards, aud the involucral
leaves being directed upwards at right angles, give the stems of this and some allied species an obrapt appearance.
The areolation is similar to that of G. Urmlleana. A few stems of apparently the same species have been
picked from a specimen of Marchantía globosa, Bischoff, from the Cape-sof Good Hope. G. concinna is closely allied
to G. lutescens, from tbe East Indies, and G. Bustillosii, Mont., from Peru, but is easily cUstingiiished by the clia-
racters above given.—P l a t e CLXXIX. Fig. 6 ; 1 , a portion of the stem, with leaf; 2, apex of the stem, with

Similar in appearatice to some states of L. microphylla, but differing in the narrower outline of its stems (owing
to the shortness of the branches), and the leaves are more deeply quadrifid with more acute laciniæ, which are not
