The same gentleman is persuaded that by such intermix- 
ture new species may be created among vegetables, capable 
of continuing a distinct race by the natural descent of an 
unadulterated progeny, to an indefinite extent, and with- 
out reverting to the single form of either parent-plant. 
As far as we have an opinion on the subject, it tends to 
the reverse of this position. We believe no truly hy- 
brid plant, under any circumstances, will continue an un- 
adulterated descent through seeds beyond a very limited 
number of degrees; and that the less complete productions 
of this kind, such as take place between remarkable varie- 
ties of one species, revert to the single likeness of either 
parent, or assume new appearances in endless vicissitudes. 
The present plant takes after the RuopopENDRON in its 
coriaceous evergreen foliage, the number of its stamens, 
the redness and expansion of the limb of the corolla; after 
the AzatEa in the blueness of the leaves, the tapering of 
these towards each end, in the cylindrical elongation and 
whiteness of the tube of the corolla; and interchangeably 
after both parents in various points of smaller note. 
It may be observed that although the plant is a mule 
of two species of different genera, and not of two species 
of one genus, yet as these genera might have been easily 
kept in one, being such as are very closely allied in nature, 
for Azavea varies with five and ten stamens, in the same 
species; that the term “ bigeneric hybrid,” in this instance, _ 
is more formal than essential.
