Of the existence of hybrid or mule productions from 
- ‘two plants of distinct species of the same genus, or even of 
different nearly allied genera, no one can have to bein-

instance of this kind, having been raised by Mr. Herbert, 
at Spofforth, near Wetherby, from seed ripened on: the 
common white glaucous-leaved Azazea, in the flower of 
which the pollen or dust from the anthers of RHopoDEN- 
DRON maximum had been purposely substituted for that of

Mr. Herbert, to whom we feel greatly obliged for this 
_-yery curious specimen, and for the information relating to 
it, says; “ that the plant is now four years old, and forms a 
“ straight upright growing branching shrub, of about three 
“feet in height, and about the thickness of a finger near 
“ the root; that the young leaves on their first appearance

“the drawing was made, had been flowered in the hot- 
“ house, and is at present unique; only one seed having been
