CHEIRANTHUS scoparius. : Chameleon Wallflower. 
From an incidental remark, in relation to the curious ~ 
transitions of colour in the corolla of some species of Cuxt- 
RANTHUS, in the above “ Mémoire,” we perceive that the 
“ Chameleon Wallflower,’ published in our Register (vol. 3. 
fol. 219), as a possible, though extraordinary variety of Cuzt- 
RANTHUS Cheiri, had in fact been already specifically in- 
stalled in the system; but under a designation much too 
brief and indefinite for our powers of discrimination, until 
aided by the remark above alluded to. The plant belongs, 
without doubt, to Cuerranruus scoparius of the 2d vol. 
p- 681 of Willdenow’s Enumeratio Horti Regii Beroli- 
nensis; distinguished from the Wild Common Wallflower 
(specifically removed from Cheiri, the garden sort, under 
the title fruticulosus) by a strigose pubescence.  Strigose is 
however an epithet that we should never have thought of 
applying to such fur as covers this plant, at least in the state 
we See it in our gardens. 
C. scoparius is said to have been originally observed in 
the Island of Teneriffe, by M. Broussonnet. It has been 
cultivated in the Royal Garden at Berlin for these ten years 
past or. more; and we find that it was from thence that 
the plant was introduced amongst us, not from Moscow, 
as we had been informed. It is now becoming very com- 
mon; being nearly hardy and very easily propagated by 
cuttings and seed. We shall mention the subject again in 
the appendix of the present volume.
