(J. ventricosa.) 
BRITISH JUNGERM ANNIiE. 
Plant growing sometimes in densely-matted patches, at other times singly, creeping among 
Sphagnum latifolium and capillifolium, or Dicranurn glaucum. 
Root consisting of rather thickly-placed, whitish, simple fibres, shooting out from nearly 
the whole length of the under side of the plant. 
Stems from half to three quarters of an inch in length, and the tenth of a line in diameter, 
procumbent, flexuose, rarely simple, more frequently once or twice branched, with the 
branches having the appearance of being again divided, in consequence of the inno- 
vations : they are of a green color, sometimes approaching to a brownish-black, and I 
have lately received specimens from Mr. Lyell, in which both the stems and roots have 
a deep purple tinge. 
Leaves rather closely placed, though scarcely imbricated, bifarious, distichous, patent, 
or even occasionally deflexo-patent, with the lateral margins always more or less 
incurved (f. 4), about a quarter of a line in length, of a subquadrate figure, divided at 
the extremity bv a wide and obtuse notch, of which the points or segments are acute, 
and, in the extreme leaves, sometimes involute ; the lower ones, it is to be remarked, 
are cleft into three (f. 5), or, which is more rare, four teeth (f. 6) or segments, which 
are frequently of unequal sizes : the texture is rather delicate, the cellules small, 
roundish ; the color a pale green, assuming more or less of a brownish tint, in much 
exposed situations. 
The perigoninl leaves do not differ from the rest (f. 9). 
Perichcetial leaves (f. 7) closely embracing the calyx, cut at their extremity into three, 
four, and even five acute, and large, but unequally-sized teeth. 
Male Fructification. Anthers (f. f. 9 10. 11) situated, two or three together, in the axilla of the 
terminal leaves. Hitherto I have only observed them on distinct individuals from those which 
bear female fructification. The form of each anther is ovate, or rotundo-ovate: the older ones 
are of a greenish ash-color, and strongly reticulated. The footstalk is about half the length of 
the anther, white, and marked with transverse lines. 
Female Fructification terminal, though very frequently, as is represented in the plate, it has 
the appearance of being lateral (f. 3), from young shoots*, which arise immediately beneath it. 
The calyx is remarkable for being in its early state of a spherical figure (f. 3), and I was 
unfortunately not acquainted with the fructification in a more advanced period of its 
growth, till a long time after the plate was engraved. By specimens, however, which 
1 have lately received, I am enabled to add that the calyx, at the time it produces 
capsules, is oblongo-ovafe ; at all times plicate towards the extremity. The mouth is 
contracted and minutely toothed. 
Calyptra. ovate, whitish, tipped with its tubular style. 
Barren pistilla (f. f. 14. 15) six or seven in number, linear, of a greyish color, longi- 
tudinally marked with reddish lines, their apex a little expanded. 
Peduncle from a quarter to half an inch long, white, shining, transversely and 
longitudinally striated. 
* Probably Micheh was deceived by this circumstance. His figure, however, gives the idea of the calyx being 
sessile, in the centre of a plant that is branched in a stellated manner ; which is not the case in any species that I am 
acquainted with.
