Has. St. Helena. 
Tufts loose, dark brown, the younger olive-coloured. Stems 
scarcely 1 inch high, very sparingly branched. Leaves from - 
a narrow base rotundato-quadrate, divided by an oblique : 
sinus into two unequal spines, of which the anterior is much 
the larger, the segments pointing to one another. À 
This is very like our Jung. anisodonta, from the same . 
island. The leaves are shorter, wider above, by no means … 
decurved, while their superior margin is scarcely decurrdig : 
and less recurved. x

Has. St. Helena. E 
Tufts loose, wide, purplish-red. Stems slender, about! | 
inch high, sparingly branched; branches upright. Leaves - 
closely imbricated, tumid, all pointing to one side, their tops. 
deflexed, their bases amplexicaul. Very nearly related to 
Jung. schismoides, Mont.; but our plantis smaller, and its 
leaves are less imbricated, more obtuse, quite entire, viet 
their segments obtuse. 
5. J. obvoluta, n. sp.; caule cæspitoso adscendente vage 
ramoso, ramis erectiusculis, foliis imbricatis patentibus di- 
midiato-ovatis involutis margine undulatis emarginatis hic 
ilic dentatis subdecurrentibus, stipulis majoribus rotum"
