Crucifer ce.] 
THE COLONY OE VICTORIA. 
33 
segments of the leaves of the indigenous variety often diminutive in a few or several pairs, the upper one 
however often as long as the width of the terminal lobe, with broad base, sessile. Upper leaves about 1 inch 
long, sessile, bluntly auriculate or acutely sagittate at the base, laciniate or toothed or repand, the lower 
incisions deepest. Racemes terminal, solitary or several approximated, many-flowered, in age considerably 
stretched in length. Flowerless portion of peduncle short. Flower-bearing pedicels 2-3 lines long, fruit¬ 
bearing ones gradually thicker, about 4 lines long, angular, somewhat spreading. Sepals yellowish, about 
2 lines long, oblong and linear-oblong. Petals oblong-spathulate, not very considerably longer in the 
Australian variety, although so in many European forms of this plant, pale towards the base. Longer 
stamens about as long as the calyx. Filaments narrow-linear subulate, one-nerved, as if capillary and 
membranous-winged. Anthers yellow, cordate-oblong, inserted above the base, in age reflexed. Fruit-style 
obliterated or about half a line long and then conical, in extra-Australian specimens sometimes frilly 1 line 
long, terminated by a minute almost undivided circular stigma. Silique in the Australian variety I-IJ inch 
long and fully 1 line broad, yet scarcely less in width in some European specimens; its valves concave- 
convex, prominently one-nerved and distinctly veined. Septum pellucid, perfect, gradually separating from 
the replum. Funicles scarcely half a line long. Seeds numerous, pendulous, ovate-roundish or orbicular, 
compressed, reticulate with innumerable foveoles, pale brown, nearly 1 line long. Testa not distinctly 
mucilaginous, wrinkled or even slightly warted. 
I cannot point out any specific characters between the Australian and European plant, particularly such 
by which it could be separated from the variety B. stricta, Anclrz ., of the northern hemisphere. 
The varieties of Cardamine hirsuta prove the length of the petals, compared to that of the calyx, to be 
a dubious note of distinction in some Cruciferse; this leads yet to further reflections in regard to the value of 
the principal diagnostic of Nasturtium terrestre, and of some supposed species of Barbarea. 
TURRITIS. 
Dillen. Nov. Gen. 120, t. 6.—Tower-mustard. 
Sepals erect, almost equal. Petals unguiculate, undivided. Stamens free, without teeth. Stigmas 
united. Silique bivalved, compressed, linear, many-seeded. Valves one-nerved. Septum broader 
than the seeds. Seeds biseriate in each cell, smooth, compressed-ovate, bordered. Cotyledons accum- 
bent, with their edges turned to the placentae. 
Annual or biennial, erect herbs, often with simple and floccous or furcate hair partially downy, 
noticed throughout Europe, in the temperate and arctic zone of Asia and North America, very rare in 
South Africa and in South-East Australia. Stem-leaves clasping, radical leaves tapering into a petiole. 
Racemes terminal, lengthened. Petals white, rose- or cream-colored. Silique generally elongate.—

Some American species render the transit from Turritis to the genus Arabis perfect.

215.—Smooth Tower-mustard. 
Radical leaves rough-downy: stem leaves from a sagittate base ovate- or oblong-lanceolate, rarely 
linear-lanceolate, glabrous, glaucous, mostly entire; pedicels of flowers almost erect; petals yellowish-white; 
siliques strictly erect , many times longer than their pedicel; seeds with a very narrow border. 
On the banks of the rivers CobongTa, Mitta Mitta, Living’stone Creek and Snowy River, at an elevation 
of from 3000 to 4000 feet. 
The identical species is known to exist in Europe, in Asia as far south as the Himalayan Mountains, 
and in North America.
