denberg, except that the summits of the stems do not curve 
in so circinate a manner; but it is to be observed that such 
circinate summits are truly perigonia, which have leaves 
smaller, more ventricose and more erect than the cauline; 
some of them containing in the axille each a single, rather 
large, pedicellated anther.

foliis laxe imbricatis erecto-patentibus late ovatis acuminu-

Tufts some inches in diameter, inferior parts dark brown, 
upper whitish-tawny. Stems scarcely one inch long, upright, 
slightly curved at the top, scarcely branched except by 2 - 
pair of new shoots from the top of the stem or from the base —— 
of the perichetium of the preceding season. The leaves —— 
from a narrow base are widely ovate, having three or four 
large teeth of which the terminal is the greatest and gives an 
acumination to the leaf; the anterior margin is slightly re- 
curved and decurrent in front of the stem. The perichætium 
has its leaves erect, elongated and deeply toothed. The! 
grown calyx does not exceed the perichetium in height, 
and is from a narrow base oblong, slightly bent to one 
side and at its mouth has a pair of dentato-ciliate, acu- 
minate lips. 
Jung. decipiens, Hoox., is very analogous to the be 
this, however, has the inferior as well as the upper *€ 
constantly toothed, their tops are more decidedly ac 
and above all, their structure is more dense, consisting ' 
very minute, scarcely distinguishable cellules. 
13. J. pleurata, n. sp.; caule cespitoso erecto subramoso, 
foliis laxius imbricatis erecto-patentibus obovatis pauci 
dentatis, margine anteriore recurvo, calycibus basi nudis 
elongato-obovatis costatis, ore minuto denticulato.
