MACQUABIB Island, Fraser, Scott! Hamilton! Also in Terra del Puego, Port Famine, 

 Hermite Island, Kerguelen's Land, Marion Island, Yong Island, and the Crozets. 



The description of the flowers and fruit is taken from Hooker, the specimens from Macquarie 

 Island being sterile. This singular plant forms large amorphous cushion-like masses, sufficiently 

 compact to bear the v?eight of a man with but little injury ; the upper surface consists of the living 

 plant, while the base is composed of decomposing leaves and roots. 



2. A. exigua, Benth. and Hook. f. in Gen. PI. i. 875. Leaves densely 



crowded at the apex of a stout rootstock, ^in. long including the stout petiole, 



glabrous ; blade orbicular-ovate, cordate, obscurely 3-lobed, coriaceous, minutely 



papillose ; margins recurved ; petiole dilated and sheathing at the base. Scape 



3— 5-flowered, usually shorter than the petiole ; involucral leaves linear, obtuse, 



coherent at the base. Calyx-teeth minute, acute. Fruits j^gin.— jJjyin. long, 



almost tetragonous, rounded at the angles. Carpels obscurely 5-ribbed on each 



face. — Pozoa exigua, Handbk. 88; Buch. in Trans. N.Z.I, xiv. (1881) t.
