PLANTS INDIGENOUS TO 
[ Crucifem. 
linear. Corymbs closely many-flowered, gradually lengthened into racemes. Sepals about 1 line long, pale 
particularly towards their margin, oblong or oval. Petals pale yellow ovate-spathulate. Stamens about as 
long as the corolla. Anthers yellow, ovate-cordate. Pollen-grains ellipsoid, bursting longitudinally. Glands 
at the base of the stamens small. Style persistent, short and stout, in rare instances 1 line long. Stigmas 
confluent into one, which is orbicular and slightly bilobed and soon not thicker than the style. Germen 
truncate or emarginate at the apex. Silique spreading, generally 2-4 lines long and blunt, ellipsoid, rarely 
broad ovate and only 1J line long, or when more lengthened cylindrical fully 5 lines long, in both cases the 
fruit-stalk respectively longer and shorter than usual. Fruit-style of \ line length. Septum J-l line broad, 
pellucid, perfect. Pedicels and replum persistent. Seeds numerous, line long, pale fulvous, oblique, 
verging more or less into an ovate round or cordate form. Testa much more closely dotted-reticulate than 
in N. officinale, also of a paler color. Funicles short, unequal. 
On account of its cress-like taste the plant is now and then used as a vegetable. It flowers here 
throughout the year. That no other Nasturtia should range so widedly over the globe seems inexplicable. 
The closely allied N. amphibium and N. silvestre produce both petals considerably longer than the calyx. 
The plant enumerated as an Australian one, under the name of N. amphibium, by R. Brown, in the appendix 
to Flinders’ Voyage, is probably referable to N. terrestre. 
The genuine white flowering* English water-cress (Nasturtium officinale) has been noticed in a few 
streamlets of Australia, but everywhere its importation from home could be traced. 
BARBAREA. 
It. Brown , in Aiton Hort . Kero , ed. ii. vol. iv. 109.—Winter-cress. 
Sepals erect, almost equal. Petals undivided. Stamens free, without teeth. Stigmas confluent. 
Silique bi-valved, linear, almost cylindrical or compressed-tetragonous, few- or many-seeded. Valves 
strongly one-nervecl. Septum not much broader than the seeds. Seeds vn each cell unisemte , 
dotted-reticulate, without a border. Cotyledons accumbent, with their edges turned to the placenta?. 
Erect generally biennial or perennial herbs, noticed in moist places of the temperate zone of 
Europe, Asia and North America, in the mountainous part of India, and likewise in South-East 
Australia, Tasmania and New Zealand. Leaves partially lyrate-pinnatifid or pinnatisected, partially 
and in a few species all merely toothed ; their stalk auriculate at the base. Racemes terminal. Sepals 
frequently somewhat petaloid. Petals yellow.— Cand. Syst, ii. 205 ; Endl. Gen, 864.

Lower leaves lyrate pinnatisected; their terminal lobe orbicular- or ovate-subcordate; their lateral 
lobes small oblique ovate or oblong or lanceolate or oblong-linear; upper leaves spathulate, obovate, rhomboid 
or cuneate, toothed or pinnatifid; flower-bearing pedicels crowded; catyx rather large; siligues erect or slightly 
spreading , compressed-tetragonous , linear . 
On the banks of the Mitta Mitta, the Mitchell and other rivers of Gipps Land, chiefly at an elevation 
of from 1000 to 3000 feet. A native also of New Zealand and Tasmania, of nearly the whole of Europe and 
parts of Asia, extending* to the mountain chains of India, seemingly introduced into North America. 
An erect somewhat mucilaginous herb, of a bitter and disagreeable taste, attaining the height of 1| to 
several feet, glabrous or scantily hairy. Root livid, sending out more or less capillary fibres and lateral 
branches. Stem streaked, simple or generally not much divided. Radical and lower stem-leaves long 
stalked; petiole of the latter dilated into a sagittate-lobed clasping* base. Terminal segment of the lower and 
low est leaves 1-3 inches long and almost as broad, repand, sometimes sinuate veined and penni-nerved; lateral
