PLANTS INDIGENOUS TO 
[' Crucifers . 
A biennial herb, from 1 to 3 feet high, with a solitary or several simple or erectly branched cylindrical 
pruinous stems. Boot tapering or almost cylindrical or somewhat branched. Radical leaves 1 or several 
inches long, toothed or less frequently sinuate or entire, quickly emarcescent, spreading, oblong-cuneate 
occasionally almost lyrate, as well as the petioles and the lower part of the stem downy with rather stiff simple 
and divided hair, the latter more frequently covering the leaves, the former clothing chiefly the stem copious 
curved and turned downward. Stem-leaves numerous, erect or slightly patent, 1-3 inches long, J-l inch 
broad, rather acute, as well as the upper parts of the plant smooth. Pedicels slender, mostly numerous, at 
first densely corymbose and then hardly longer than the flower, soon dispersed in an often foot-long always 
bractless raceme, and then from 3 to 8 lines long. Sepals about 2 lines long, pale, membranous, three-nerved, 
veined, narrow-oblong, blunt at the apex, truncate at the base. Petals obovate-cuneate, not much or nearly 
half longer than the calyx, tapering - gradually into the unguis. Stamens tetradynamous; the longest nearly 
as long as the petals. Filaments pale, linear-subulate. Anthers yellowish, line long, linear-oblong, 
bilobed at the base, in age recurved. Pollen-grains blunt ovate-ellipsoid, bursting lengthwise. Germen and 
stigmas sessile; the latter confluent into a solitai*y depressed indistinctly bilobed one. Siliques 1|— 2 inches 
long, hardly 1 line broad. Valves blunt, thin-chartaceous, somewhat veined. Septum membranous, nerve¬ 
less. Funicles capillary, shorter than the seeds. Seeds pendulous, forming two rather irregular rows, ovate, 
by mutual pressure angular, scarcely J line long, brown, with a darker narrow edge.

Toumefort, Instit. Rei Herb. 109.—Bitter-cress; Lady’s Smock. 
Sepals erect or somewhat spreading, almost equal. Petals undivided, unguiculate, sometimes 
wanting. Stamens free, without teeth, 6 or rarely 4. Stigmas united. Silique hivalved, long-linear, 
more or less compressed, very rarely lanceolate. Stipes wanting. Valves nerveless or faintly nerved 
towards the base. Septum nerveless. Seeds in each cell numerous, rarely few, unisenate, very rarely 
irregularly biseriate, seldom bordered. Cotyledons flat, accumbent; their edges facing the placenta?. 
A cosmopolitan genus, comprising annual, biennial and perennial herbs, which prefer humid 
localities. Leaves entire or variously di vided. Peduncles with racemose rarely a single flower. Petals 
white or pink.— Cand. Syst. ii. 245 ; Endl. Gen. 865. 
Cardamine radicata (J. Hook. Icon. Plant, t. 882 ; Flor. Tasm. i. 18) differs from most if not all 
species in producing a leafy bract at the base of each pedicel, in the exactly lanceolate siliques, 
containing but few seeds in each cell. It offers thus an approach to Dentaria and Pteroneuron, and 
thence to the tribe Alyssineae, deserving therefore to be held distinct as a subgenus, to which the name 
Platyphragma might be given. This species was noticed on the summit of Mount Lape'rouse of 
Tasmania, by Mr. Oldfield, and may possibly be found to extend to the Victorian or New South Wales 
Alps. 
Cardamine stylosa, Cand. Syst. ii. 248; J. Hoolt. FI. Tasm. i. 18; Arabis gig-antea, Hook. Icon, 
t. 259.—Long-styled Bitter-cress. 
Smooth; stems leafy, generally long, flaccid, branched ; leaves oblong-lanceolate, sessile, tapering into 
a sagittate entire base, minutely and remotely toothed; racemes in age much elongated; pedicels stout, 
spreading, three to six times shorter than the silique, bractless; petals rather small, less than half exserted; 
stamens about as long as the calyx; anthers yellow; siliques very spreading, rostrate; valves towards the 
base faintly one-nerved; funicles very short, tooth-like; seeds darh-brohm, densely reticulated. 
In liumus-soil of moist forest valleys, rarer in open pasture land near the banks of rivers; in various 
parts of Gipps Land, for instance, near Wilson’s Promontory, on the Jack River, at Sealer’s Cove; also in 
the Dandenong Ranges. Beyond Victoria, through New South Wales, as far north as Mount Linsav, where
