of New Zealand and a Tasmanian species, may ultimately prove distinct from this plant, which, besides being universally distributed throughout Europe, is abundant in North America under the names of C. hirsuta, C. Pennsylvanica, C.Yirginica, &c, whence it probably passes along the Andes into South America, for we have specimens from Colombia. It is likewise an inhabitant of the Pacific Islands, of Ceylon and the Indian Peninsula, and of the Island of Mauritius.
The other Chilian species of this genus are : 1. 0. affinis, Hook, and Am. (Bot. Miscell. vol. iii. p. 137), this has the general appearance of C. hirsuta, but the flowers are considerably larger and the pods gradually acuminated into long styles, (a native of Conception) ; 2. C. tenuirostris, Hook, and Am. 1. c., similar to the last, but the pods are larger, the leaves more numerous and cut into many linear segments, (Conception) ; 3. C. tuherosa, DC. (Syst. vol. ii. p. 254 ; Deless. Icon. vol. ii. t. 29), this has simple large and orbicular leaves, cordate at the base ; the tuberous root in the genus frequently is owing to local causes (Valparaiso) ; 4. C. Chilensis, DC, 1. c, has the leaves entire or with one small lobe at the base, elliptical, obovate, and obtuse, (Chili, Bertero) ; 5. C. chenopodiifolia, Pers. (DC. Prodr. vol. i. p. 149), it and the preceding belong to the entire-leaved section ; the present has the habit of Arabia Maclovianu, but the valves of the pods are plane and entirely nerveless (it grows near rivulets on the Andes, altitude 8000-10,000 feet (Bridges); 6. C.fiaccida, Cham., Bertero's imperfect specimen bearing this name (Mus. Brit.) with the following note, "an nova species? C. macrorhiza, Bert., MSS." appears not to be a Cardamine at all.
2. Cardamine geraniifolia, DC. ; glaberrima, v. parce pilosa, radice lignosa, caule erecto subramoso folioso, foliis radicalibus longe petiolatis bipinnatisectis pinnulis petiolulatis late ovatis trilobis tripartitisve segmentis grosse dentatis dentibus obtusis subacutisve, floribus majusculis in corymbum pauciflorum clis- positis, sepalis pedicellum sequantibus, petalis amplis obovato-spatliulatis albis v. pallide roseis, siliquis ?

In Peru this very distinct species is replaced by two or three similar, of which one grows at an elevation of 10,000-12,000 feet on the Andes. They are more nearly allied to the C. chelidonia, Tenore, of Italy, than to any other of the genus.

Hab. Strait of Magalliaens, by the margins of alpine woods; Commerson (in Herb. Hook.).
The only specimen of this plant that I have seen was derived from the Herbarium of M. Gouan, and is marked by him as received from Commerson ; it is quite undistinguishable from B. incana, under which name, I, alono-with Torrey and Gray in the Flora of North America, include B. confusa, Ehrh. The specimen is about 8 inches
