This name has been deduced from the Greek 
ERUO, to draw, expressive of its quality of producing 
blisters. Some species of the genus are acrid and 
stimulant, and amongst them possibly may be com- 
prised the original plant of the ancients. The spe- 
cific name, it is likely, was adopted in honour of a 
Russian botanist. 
The seeds of this species of Erysimum, were sent 
us, from St. Petersburgh, in December, 1838, with 
a note subscribed B. P. G. stating that the writer 
had seen it in flower in two of the imperial gardens, 
and that according to Fischer and Meyer the seeds 
had been introduced from Cabul, a Country of Asia, 
west of the Indus. Should this meet the eye of 
our obliging correspondent, we offer him through 
this medium, having no other, assurances of our 
gratitude. 
The Erysimum Peroffskianum is admirably 
adapted for producing a gay effect in large masses, 
and it is rendered doubly desirous from the little 
care which it demands. Seeds sown in the open 
borders in April, have produced plants, yielding a 
brilliant display of orange flowers in September.
