J UNGERMANIA. 509 
Jung. cordifolia belongs to a small section of the genus which we may 
eall § Luride, consisting of 3 European species, J. J. pumila, riparia 
and cordifolia, all common in Britain, and all notable for the olive-green 
colour of the ovate-oblong, or somewhat heart-shaped leaves ; for the 
dichotomous, or lateral branching (with the addition of postical flagella 
in J. riparia) ; but especially for the perianth being compressed frontally 
instead of laterally, and having a furrow in place of a raised keel along 
the middle of the upper face. In J. pumila (which is paroicous, while 
the other two are dioicous), the perianth is fusiform, with a minute 
edentate orifice at the acute apex, beneath impressed (until inflated by 
the ripe capsule) with no evident folds, above obtusely 2-plicate with a 
narrow furrow between the folds ; this furrow is at the suture of the 
flower-leaves, and is eventually ruptured by the protrusion of the fruit. 
The perianth of J. cordifolia also is fusiform and acute, but less com- 
pressed (more nearly circular on the section), and only near the apex 
slightly plicate. In J. riparia the frontal compression is slight, but per- 
ceptible ; the mediantical furrow strongly marked, and bordered by two 
pronounced keels, or folds ; while beneath it has (at least) one broad 
prominent keel, making (with the marginal keels) the perianth strongly 
5-carinate. By the duplication of the postical keel, and sometimes of 
one or more of the other keels, the perianth may become 6-8-carinate, 
especially in the upper half.

Obs. J. amena is said in ‘Syn. Hep.’ to have “surculi gemmipari tri- 
fariam foliati”; but these shoots must surely have belonged to an inter- 
mixed Odontoschisma ; for it is singular that the Peruvian J. amena grows 
along with Odont. denudatum, which bears precisely the same sort of 
gemmiparous trifarious-leaved shoots as in the Mexican plant are (wrongly) 
attributed to J. amena.—The latter is almost a miniature copy of the 
European J. lurida Dum. (=ZJ. nana Nees), differing in its slightly nar- 
rower leaves and oval capsule.
