+ Ortegopuntia cv. Percy (graft-chimera) |
The mingling of
tissues
belonging to the stock and
scion through
grafting
in a nonsexual manner. The chimaera come up as a
branch or
shoot from
the point of union which contains tissues of both
species, resulting in
a arrangement of both species being expressed in the shoot. Such shoots
can be vegetatively propagated and
cultivated.
The formula for the
graft-chimaeral nature of such a plants uses a
“ + “ sign against the
initial letter of the generic name and to connect the two "parent"
species (not the multiplication sign “ X “ this
show that they are not sexual hybrids). If intergeneric, graft-chimaeras
can be given their own genus name (which is a combination of the two
constituent generic names) preceded by a + sign. An example is: +
Ortegopuntia (Ortegocactus macdougalii + Opuntia compressa).
Graft chimaeras can be given cultivar names. The example above has been
named
+Ortegopuntia cv. Percy,
They cannot be given species names |
