INTRODUCTION. 
In regard to situation , the calyx is either terminal, as in J. asplenioides, J. exisa, &c. : Situation, 
lateral as in J.hamati folia, J calyptri folia, J viticulosa, and J Trichomanis: placed upon 
short lateral branches, as in J- Tamarisci, J albescens ( Suppl . tab. 3), and J. Sphagni 
( Suppl . tab. 4) ; or upon short branches at the base of the shoots, as in J ■ bicuspiclata 
(tab. 11) and J connivens. Lateral, upon the superior surface of the stem in Jpusilla: 
arising from the lower side of the stem in J. Sphagni and J ■ trilobata. 
The insertion of the calyx is in every instance, among the British species at least, Insertion, 
upon its base, so that it becomes erect, except in J. Trichomanis (tab. 79) and J. viticulosa 
(tab. 60), where the calyx is affixed to the stem by the side of the mouth ; and the calyx 
itself is thus pendent and buried in the earth. I have seen a similar instance in a species 
brought by Mr. Menzies from New Zealand, where, however, it is terminal upon an 
upright growing plant, and, consequently, never buried in the soil, like our species. 
Among the frondose Jungermanni®, we find two species which possess the peculiarity Double Caly 
of having a double calyx, J. Lyel/ii (tab. 77) and J. hibernica (tab. 78) ; of these, the 
outer is small and laciniated , the inner much larger, and ovate or oblong : in one, it 
exceeds the length of the calyptra ; in the other it is shorter. A still more remarkable 
circumstance takes place in J . Blasia, where the calyx is imbedded within the substance 
of the frond (tab. 83). In J. epiphylla it originates on the upper surface ; in J. pinguis 
and J. multijida (tab. 45) at the side; and in J.furcata from the underside of the nerve. 
PISTILLA. 
Of these there are from three to eight or ten which are immediately surrounded by Pistllla * 
the calyx, or, in the absence of that, by the perichietial leaves. Their form is linear, and 
approaching to lanceolate in some species; but short and ovate in J. pinguis, J.Jurcata, 
and J. multijida: their mouth is always slightly expanded. Their structure likewise 
appears to be cellular : their color is whitish or pale grey with a few reddish longitudinal 
striae. One, or rarely two, of these pistilla is made fertile ; and then the lower part swells, 
and becomes the germen, of an olive green color, whilst the upper remains as the style, 
varying in length in different species. Of this germen, the exterior part (which seems to 
have some affinity with the arillus of the Carices) constitutes what is called the 
CALYPTRA: 
this consequently takes the form of the full-grown germen: it is membranaceous in Calyptra. 
the greater number of species ; subcarnose in J. epiphylla, J. pinguis, J. multijida, and 
J.Jurcata ; but, smooth in all, except the two last, of which, in J. multijida, it is tuber- 
culated, and in J.furcata hispid. When the germen is sufficiently large: the interior part, 
now become the capsule , bursts with an irregular vertical opening at or near the summit, 
and the capsule elevated upon its white, cellulose 
PEDUNCLE, 
is protruded to various lengths, according to the species; being very long in J. epiphylla Peduncle, 
and J. pinguis; short in J.furcata, J.platyphylla, J.junipenna , &c. In J heterophylla it
