pools was in some rare instances enlivened by the large flowers of the 

 Ficaria-like Caltha ? sagittata. 



The following is a List of the plants found growing in Southern 

 Terra del Fuego ; at Good Success Bay in the Straits of Le Maire, 

 and at Orange Harbor : 



Ranunculus (No. 23). In moist places, in the shade of the forest.* 



Ficarioid sagittata, (No. 1) ; Caltha of Cav. Carpels twenty or more. On the denuded 



muddy soil at the margin of mountain-pools; rare. 

 Nov. Gen. appendiculata, (No. 1) ; Caltha of Commers., but widely dilfering from that 



genus in its diminutive flowers and singular foliage. 

 (No. 2) ; a congener of No. 1. Densely cespitose in congested alpine bunches, 



and having small entire leaves. Frequent, but very rarely seen in flower. 

 (Drymis Winteri, No. 1); Wintera aroniatica of authors. The largest forest tree; occur- 

 ring singly, at wide intervals, and in full flower at the time of our visit. The one on 



the South side of Burnt Island, may prove the largest tree growing so far South; 



Cape Horn being in plain sight. 

 Berberis ilicifolia, (No. 2). A large shrub, eight to twelve feet high, with the stem an 



inch in diameter. Frequent in the forest, but the flowers and fruit rare. 

 — " dulcis ? " (No. 3) ; the leaves entire, and of more tender consistence. A shrub, 



of equal dimensions with No. 2, and in like manner growing in the forest. 

 Brassica? (Magellanlca, Pers., No. 3) ; compare Sisymbrium and Nasturtium. The leaves 



dissected and much divided ; flowers large, yellow. " Grood-Success Bay," Rich. 

 Cardamine (glacialis, Dec? No. 11); scurvy-grass. Allied to C. hirsuta; flowers large, 



white. Along the sea-coast; not abundant. 

 Viola (No. 28). Deiisely-cespitose in congested alpine bunches; the leaves bilobed. 



Confined chiefly to the mountains. 



. maculata ? (No. 29) ; normal. Rather frequent. 



, perhaps a third species. 



Drosera uniflora, (No. 11). Growing on moist declivities. 



(Colobanthus) crassifolius, (No. 1); Sagina of D'Urv. The capsule four-valved. 



( — ) subulatus, (No. 2) ; Sagina of D'Urv. Closely and diminutively cespitose, the 



leaves being very short and rigid. On mountain-summits. 

 ( perhaps other species. 



Stellaria debilis, D'Urv. ? (No. 12) ; diff"use. " Good-Success Bay," Rich. 

 Cerastium (Ko. 9). A foot high ; the leaves linear. Growing along the sea-coast. ' 



• (No. 10) ; leaves linear, hairy. Seen only on mountain-summits. 



Oxalis Magellanica, (No. 21). Abnormal; diminutive; trifoliolate. Growing on moist 



rocks projecting out of rills in the shade of the forest; somewhat rare. 

 Gen. incert. (No. 1). Having .something of the aspect of Samolus; leaves fasciculate, 



glaucous, linear, obtuse ; petals five ; stamens five ; capsule superior, three-celled, 



many-seeded. 



'Urtica (No. 22). Resembling U. urens. Only one stock met with ; and this was grow- 

 ing in the centre of a deserted Fuegian hut, the seed having doubtless been uninten- 

 tionally brought there by the natives. The only foreign or displaced plant met with.
