This, of which I have seen but a single specimen, must be one of the handsomest Fuegian plants ; it is apparently very scarce, for it does not exist in the collections of Capt. King or Mr. Darwin, nor have I myself gathered it.

2. Ourisia IreviJIora, Benth.; humihs, pilosa, caule ascendente foliato 2-4-floro, foliis petiolatis ovato-orbiculatis basi truucato-subcordatis floralibus sessibbus ovatis, calycis segmentis bneari-oblongis tubo corollas longioribus. Benth. in DC. Prodr. vol. x. p. 493. (Tab. CXVIII. sub nomine 0. Antarctica).

Hab. Strait of Magalhaens, Port Famine, Capt. King ; South part of Tierra del Fuego, C. Darwin, Esq.

Hermite Island, in clefts of rocks on the mountains, /. D. H. Caules basi ramosi, 2-3-pollicares. Folia vix semi-pollicaria. Calycis segmenta fere 3 lin. longa, angusta, obtusa. Corolla limbus valde obliquus, laciniis emarginatis, iufima quam tubus paulo longior. A pretty Uttle species, probably not rare in Fuegia, though readily overlooked from its very diminutive size. When the accompanying plate was prepared and the name 0. Antarctica applied to it, I was not aware of Mr. Bentham having named the plant in the then unpublished volume of De Candolle's Prodromus. The genus Ourisia is highly interesting, from being among those peculiar to the Antarctic or higher latitudes of the southern regions, which have no analogue in the northern, but which, though most abundant in Antarctic America, have representative species in the temperate portions of Terra Australia (O. integrifolia, Sm.), and in New Zealand or temperate Polynesia (O.maeropltyUa, Hook.). Plate CXVIII. (under the name of O.Antarctica). Fig. 1, flower; fig. 2, corolla laid open ; fig. 3, ovarium; fig. 4, transverse section of the same j fig. 5, ripe fruit ; fig. 6, transverse section of the same ; fig. 7, seed ; fig. 8, longitudinal section of the same : — all magnified.

Herba perpusilla, vix poUicaris, glanduloso-puberula. Caulk erectus, simplex v. divisus, foliosus. Folia 1-3 lin. longa, cuneata, in lacinias 3 lineares obtusas ad medium fissa. Flores inter folia summa sessiles, pro planta magna;. Calyx tubuloso-campanulatus, glabriusculus, breviter 5-fidus, lobis obtusis, apice puberulis, marginibus siccitate atratis.

A very minute species ; also found at Coquimbo in Chili, by M. Gay. It is the southern representative of
