Has. Hermite Island, Cape Horn; in tufts of mosses, &c. 
Cespites pallide flavo-virescentes. Caules 1 unc. longi, basin versus precipue ramosi. Folia laxe imbricata, 
grosse reticulata, ad medium in segmenta dua acuminata divaricata figsa, margine dorsali decurrente et recurvo. Peri- 
gonia in spicas terminales disposita; foliolis -arcte appressis, basi tumidis, antheriferis, segmentis foliis caulinis

Allied to J. leptantha, but a smaller plant, with leaves of a different shape, being narrower at the base and 
deeply divided beyond the middle. The stipules are bipartite. : ۱

Has. Falkland Islands; on wet sand and clay-slate. 
Cespites sub 2 unc. lati, pallide flavo-virides. Caules breves vix + unc. longi. Rami e caule prostrato erecti,

Perhaps the most minute of the Lophocolee, from all the species of which its habit and the form of the leaves 
amply distinguish it.

Allied to J. planiuscula (Pt. 1. t. 65. f. 2), which is a larger plant, with differently shaped stipules. Also near 
the following, which, again, is smaller than either, with leaves of another form.
