JUNGERMANNIA SACCATA. 
Jungermannia caule procumbente, ramis erectis, foliis 
bifariis ovato-quadratis denticulatis, fructu terminal, 
ealycibus oblongis carnosis pendulis.. (Tas. XVI.) 
Has. In sinu Dusky Bay dicto. D. Menzies, 1791. 
Caules repentes, flexuosi, radiculosi, ramosi. Rami erecti, flexu- 
osi, apice, in fertilibus, incurvi, simplices, subtripollicares, 
basi denudati, superne foliosi. Folia distantia, bifaria, disti- 
cha, ovato-quadrata, horizontalia, subverticalia, planiuscula,, 
subrecurva, basi decurrentia, margine superne denticulata, 
inferne integerrima. Calyx in apicem ramorum situs, oris. 
margine hine affixus, oblongus, pendens, earnosns, ore parvo, 
subeontracto, foliaceo, prope marginem macula rotundata, in. 
qua pistilla reperiuntur. Corolla nulla. Seta longa, digitalis 
et ultra, alba, succulenta, medium versus incrassata. Capsula

We have among our British Jungermannie two species (viz. 
J. viticulosa and J. trichomanis), which have calyces pendent 
on the stalk; but then they are buried in the ground, or in 
the mosses and other plants among which they may happen to 
grow. In the present instance the calyx grows from the extre- 
mity of an erect stem, or which is curved only, as it would ap- 
pear, from the weight of the fructification, and there is pendu- 
lous. On the exterior surface of this calyx, near the mouth, 
is a cluster of pistilliform bodies, apparently covered by a mem- 
brane, and these are present at the same time with the perfect 
capsule, In the foliage and stems this plant has great affinity 
with J. asplenioides,
