This, which is undoubtedly the common English "Cleavers," appears truly wild in Fuegia, having been found at three very remote stations, two of them scarcely visited by Europeans ; it is also a native of the Island of Chiloe, of the Cape of Good Hope, and in North America it ranges between the latitudes of Fort Vancouver and the Mississippi River.
2. Galium Chilense, Hook, fil.; ammum, scaberuhun, caule debili sirnpliciusculo, foliis quinis senisve patentibus oblongo-lanceolatis in aristam acuuiinatis super marginibus nervoque dorso retrorsum scaberulis, pediuiculis umfloris solitariis florentibus brevissimis fructiferis validis folio subtequilongis, fructibus hispidopilosis.
Hab. Clionos Archipelago ; C. Darwin, Esq.
Caitles implexi, spithamsei, angulis scaberulis; ramis divaricatis. Folia subflaccida, -i— i lmc - longa, internodiis i breviora. This cannot be confounded with any other of the few one-flowered species of this genus.
3. Galium Fuegianum, Hook, fil.; annmim?, gkbriusculuni, caulibus suberectis raniosis glaberrimis, foliis quaternis elliptico-oblongis acutis obscure 3-nervibus marginibus scaberulis supremis liispidulis, pedunculis terminalibus ternis uniiloris florentibus brevissimis fructiferis validis elongatis, fructibus hispido- pilosis.

Caules spithamsei, glaberrimi, ramosi ; ramis suberectis. Folia unc. longa, subcoriacea, interdum sed rarius parce pilosa.
This approaches the G. triflorum, Mich., of the northern hemisphere, but may readily be distinguished by the quaternate leaves and the invariably simple peduncles.
4. Galium Magellan! cum, Hook, fil.; pereime?, caule suberecto parce ramoso ad angulos minutissinie hispidulo, foliis quinis lineari-lanceolatis acutis glaberrimis marginibus re urvis scaberulis, pedunculis axillaribus plerisque solitariis bifioris rarius binis et unifioris, floribus majusculis, fructibus glaberrimis.
Hab. Strait of Magalliaens ; Cape Negro, C. Darwin, Esq.
Caules 3-unciales, crecti, uitidi ; ramis erecto-patentibus. Folia patentia, subcoriacea sed non rigida, marginibus vix ac ne vix scaberulis. Flores magnitudine G. borealis, straminei ? Pedunculi fructiferi folio subsequilongi.
The present is the largest-flowered of any of the Antarctic Galia, all which, except G. Aparine, appear peculiar to the high southern latitudes.
