15. J. bicuspidata, L. Sp. Pl. II. p. 1589. 
Has. Falkland Islands. 
16. J. rigens, n. sp. ; caule ceespitoso erecto subramoso, foliis 
imbricatis secundis concavis ovatis bifidis, segmentis in- 
curvis lanceolatis integerrimis, stipulis ovatis bifidis, seg- 
mentis subulatis incurvis integerrimis. 
Has. Falkland Islands. 
Tufts minute, pale yellowish-olive. Stems scarcely two 
. lines long, nearly simple. Leaves diminishing in size towards 
the top of the stem, imbricated and their tops incurved so as 
to give to the shoot a moniliform appearance. Stipules large 
in proportion to the size of the plant, split down nearly to 
the base. | 
This species is analogous to the European Jung. Francisci 
Hook., but is more minute, has leaves more concave, with 
a deeper sinus and has stipules with subulate and elongated 
Incurved segments. 
l7. J. vasculosa, n. sp.; caule cæspitoso procumbente sub- 
ramoso, foliis imbricatis erectis secundis tenuibus ex lata 
decurrente basi rotundato-quadratis, margine integerrimo 
subsinuoso, stipulis majoribus concavis ovatis bifidis, seg- 
mentis lanceolatis integerrimis. 
Has. Falkland Islands. 
Patches several inches wide, blackish-green. Stems two 
inches long, sparingly branched. Leaves rather loosely im- 
bricated, their margins often inflexed, anteriorly somewhat 
gibbous, posteriorly decurrent, entire yet with an irregular 
outline; the leaves are very thin and their cells large. The 
Stipules are very conspicuous, embrace the stem and have 
two broadly lanceolate segments. 
It is difficult to say if the present should be arranged 
among the Lophocolee or the Jungermannie proper of Nees. 
€ leaves are too entire for the former tribe. The present 
Species has the air of Jung. cordifolia Hook., from which 
the presence of its conspicuous stipules at once distinguishes 
it,
