Among the few plants which have reached this country 
from Affghanistan is the present, of which seeds from Jella- 
labad were given to the Horticultural Society by Sir Henry 
Fletcher. Not knowing what it was, the specimens in the 
garden of the Society were treated as half-hardy shrubs, and 
led to twine round a trellis; they appeared to be little im- 
patient of cold short of frost, and on flowering in September 
last proved to be a mere form of the Ceylon Leadwort, the 
usual appearance of which was lost in consequence of the 
leaves having become much more wavy, and darker coloured, 
and the growth of the plant much restricted in consequence 
of the low temperature to which it had been subjected. 
The experiment proved, however, that this species is by 
no means a stove plant, as it is generally supposed to be; 
but that it may be grown perfectly well, provided actual frost 
is guarded against. 
There are few species indeed which have a more extensive 
geographical range than this. Dr. Royle states that it occurs 
in the plains of India as far as 30” north latitude; we have 
it now before us from Madras, Burma, Ceylon, and Timor ; 
and Dr. Brown found it as far to the southward as Port 
Jackson in New Holland. In none of the instances that have
