150 FLORA ANTARCTICA. [Auckland and
Tliis is one of the most universally diffused species in the Southem Hemisphere, and especially abundant
throughout the Antarctic regions; it hears considerable resemblance to the / . orhicularis, Mich., of North America,
and to several other species.

The whole of the texture of this fine species is, when wet, so flaccid, that its large closely imbricated stipules
are at first r ith difficulty distinguished from the leaves. I t is perhaps more nearly alhed to the J. seirulata, Sw.
(Muse. Exot. t. 88), than to any other; still, this is quite a distinct plant, much larger, stouter, with the leaves
somewhat fleshy and brittle, longer and more erect, of a liuid pmqile colour.

Gottsche (Synopsis, 1. c.) compares this species with J.piligera, Nees, a plant of Java ; it is perhaps more hke
J. incumbens, Lehm. of Tristan d’Acunha, differing by the greater size and nearly equal segments of the leaves.
These have no near ally in Europe.

This species has indeed many points in common with J. bicuspidata, the same pale colour, loose leaves with
large cellules, acuminated segments, and an elongated calyx. I t is marked by the smaher size, the stem-leaves
being more erect, the division of the leaf deeper, and the calyx more generally terminal than in J. bicuspidata, L.

The leaves on the fertile shoots of this species rapidly increase in size upwards, becoming more densely imbricated
; the terminal pair or periclioetial leaves are the largest and most erect.
Those species of Jungei'mannia with round, concave, imbricating leaves and bifid stipules, which inhabit the
north of Emope, have their calyces suhcylindrical or ovate ; the present differs from all of them in that organ being
decidedly compressed and truncate, appearing hke a flattened cylinder after the egress of the capsule. I t may by
some be considered as foming a separate genus, to which perhaps our J. stronyylophylla should be refeiTed.

A singularly beautiful and easily recognised plant, with much the habit and external appearance of J. notophyUa,
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 straeture, Like the
