crucifem;. 
Generic Character.' — Pods four-sided. Seeds destitute of margins. Cotyledons incumbent. Stigma 
capitate, then emarginate, with spreading lobes. Calyx erect. 
Specific Character. — Plant annual or biennial, with bipartite setse, scabrous. Stem simple. Leaves

of the petals scarcely longer than the calyx. Seed-pods covered with bipartite scabrous setse, nearly 
round, and five times the length of the pedicels. 
Seeds of this very showy border plant were received at several places in Britain 
from Dr. Fischer of Petersburgh, in 1838 ; and, considering this is the first season 
in which it has flowered perfectly, we have been astonished to find it in so many 
collections. It is, however, one of those plants, the seeds of which ripen in such 
abundance, that it will very shortly be met with in every garden where new and 
ornamental species are grown. 
In the form of its flowers, it bears so close a resemblance to the common "Wall- 
flower, that an inexperienced observer might readily mistake it for a variety of 
that universally-admired plant ; but a marked difference in their disposition 
will be seen from our representation, and in this particular E. Perofskianum pos- 
sesses a decided superiority. It is scarcely necessary to add that this consists in 
exhibiting a much larger surface of flowers. Like the Wallflower, also, it continues 
blossoming for a great length of time ; specimens that commenced blooming in 
July, having, about a fortnight since, almost as good a display of flowers as at any 
previous period. 
It must not be imagined from what we have just stated that old plants are as 
engaging as the young ones. At the present season, those that have been per- 
mitted to flower unrestrictedly during the summer months, have their flowers
