In the form of the pod tliis is intermediate between Barbaraa and Arabis, the habit is however altogether
that of the latter genus. The fact of a species of Brassica having been described as a native of the Strait of Magalhaens
seems to have induced Gaudichaud to refer his probably incomplete specimens of tbis plant to it. D’Urvüle
afterwards retained the generic name, but constituted this a new species. That the specimens of the former, and
possibly of the latter voyager also, were incomplete, is erident from M. Gay’s refen-ing it to the genus Erysimum,
from which as from Brassica it is far removed, though in the form of valves of the pods and habit it beai’s a similaiity
to some species of the fii'st named genus.

After what is said respecting this plant in the first part of the present work, it wül not excite surprise that I
now consider all the species quoted above as states or varieties of the universally diffused C. hirsuta. I have in vain
sought for specific characters amongst the numerous specimens now before me, gathered in many parts of Chili,
Patagonia, and Fuegia, at different positions on the coast and various elevations on the mountains. The ordinary
form, which bears generally the name of C. glacialis, is a smaU, glabrous or slightly hairy plant, from 2-6
inches high, spaiingly branched, with the branches leafy or naked, sometimes of a robust habit. Leaves ivith 3-5
pair of sinuated leaflets, the terminal one larger, cordate or attenuated at the base. Süiquæ on pedicels from two
to three-quarters of an inch long, erect, about an inch long, ivith acuminated or rather obtuse styles, which are
sometimes so short that the stigmata ai'e nearly sessile. From the same locabty, however, different specimens vary
much, and when growing in a sandy soü the roots become tuberous and the whole plant often hahy. In moist situations
the stems are leafy upwards and more succulent, resembbng the Campbell’s Island variety subcamosa (vol. i. p. 5), and
I have gathered individuals of a very small size on the hills of Hermite Island, with single parrs of leaflets, answering
to the C. glacialis, ß of DC., and to Buenos Ayres specimens in Herb. Hook. JIi'. Danvin has collected a form near
Valparaiso, which is not distinguishable from a large state of the plant that inhabits the Island of Ai-ran in Scotland;
it is the C. sylvatica and also Sisymbrium Nasturtium var. CJiilense, of Bertero. Some of the Falkland Island
specimens again, are identical with others gathered in Iceland, and as is the case in the Northern Hemisphere,
the flowers produced in the colder latitude are generally the largest. I am not prepared to say how far the C. debilis
of New Zealand and a Tasmaman species, may ultimately prove distinct from this plant, which, besides being universally
distributed throughout Europe, is abundant in North America under the names of 0. liirmta, O. Pmmijlvanka, C. Vir-
ginica, &c., whence it prolmbly 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 Cliilian species of this genus are ; 1. C. affinis, Hook, aud Am. (Bot. Mdscell. vol. iii. p. 137), this
has the general appearance of C. hirsuta, but the fiowcrs are considerably larger and tbe pods graduaUy acuminated
into long styles, (a native of Conception) ; 2. C. tenuirostris, Hook, and Arn. 1. c., similar to the last, but the pods
ave larger, the leaves more numerous and cut into many Unear segments, (Conception) ; 3. C. tuberosa, BC. (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. Chilensk, DC., 1. c., has the leaves entire
or with one smaU lobe at the base, eUiptical, obovate, and obtuse, (CbUi, Bertero) ; 5. C. ctoopoifii/oiin. Pers.
(DC. Prodi-. vol. i. p. 149), it and the preceding belong to tbe enth-e-leaved section; the present has the habit of
Arahis Maclomana, 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.flaccida, Cham., Bertcro’s imperfect specimen bearing this name
(Mus. Brit.) with the following note, “ an nova species ? C. macrorliiza, Bert., JISS,” appears not to be a Carda-
mine at all.

In Pei-u this veiy distmct species is replaced by two or three simüar, of which one grows at au elevation of
10,000-12,000 feet on the Andes. They are more nearly alhed to the C. chelidonia, Tenore, of Italy, than to any
other of the genus.
