 long slender peduncles. Stigma plumose.

Hab. M'Quarrie's Island. (Herb. Hook.) 



This is perhaps the most common and widely diffused species of the genus, being found abundantly through- 

 out Chili and Fuegia, as well as in the Falkland Islands and Kerguelen's Land. It may readily be distinguished 

 by its large size, and by its smooth red-brown, often glaucous, decumbent stems. The leaflets are generally 

 membranous, obovate or cuneate, ^—| inch long, coarsely inciso-serrate, glabrous on the upper surface, pubes- 

 cent or almost silky beneath. The scapes or peduncles, bearing the globose capitula, are quite glabrous. The 

 whole plant varies much in the size and toothing of its leaflets, whence I am inclined to think it may 

 be the large and ordinary form of A. Magellanica, Lam. ; although Vahl describes the peduncles of that plant 

 as " superne subvillosi." I further doubt how far the A. ovdlifolia, Ruiz, and Pav. (Fl. Per. t. 103. f. c), will 

 prove distinct ; it again is allied to the A. Sanguisorbce, Vahl. The present form was not found either in Tas- 

 mania, New Zealand, or in Lord Auckland's or Campbell's Islands. The fact of its reappearance in a higher 

 southern latitude is an interesting one, and in accordance with the known laws affecting the distribution of 

 plants.

Hab. Lord Auckland's group and Campbell's Island ; abundant. Also more recently found 

 amongst the mountains of New Zealand by Mr. Colenso. 



A very pretty species, allied to the E. nummular {folium, R. Cunn., of New Zealand, but readily distin- 

 guished by its much larger size and thin, flaccid (not fleshy) leaves, which are strongly eroso-dentate. In Mr. 

 Colenso's specimens the stems are longer, and the leaves less rounded in form with longer petioles. Stems 

 weak, terete, 3-6 inches long. Leaves in rather remote pairs, bright green and shining above, often discoloured 

 and purplish beneath, ^—§ inch long, sometimes broader than long. Petioles 1-3 lines. Peduncles, even when 

 flowering, very variable in length, from ~-3 inches long, generally erect. Sepals concave, especially towards 

 the apex, which is produced into a thickened, short, club-shaped apiculus or gland. Petals about half as long 

 again as the sepals, 1| lin. long, of a pale rose-colour, bifid nearly half-way down. Filaments thickened at the 

 connectivum. Style gradually swelling upwards into a club-shaped obtuse stigma. Capsule (which I have 

 seen ripe only in the New Zealand specimens) narrow, erect, quite glabrous, about an inch long.
