O. macdougalli
O. compressa |
Story:
This original plant appeared unexpectedly in a grafted plant, the
graft-chimaera
sprouted up as a small branch from the point of union of the
stock
and
scion
from the
callus containg
tissues
of both species.
Description: This is a very slow growing plant with an
external layer of
epidermal cell of
Ortegocactus macdougalli that
cover a second inner layer of tissues of
Opuntia compressa like a glove. The plant colour is the
unmistakable grey-blue metallic tone of the Ortegocactus, but
the plant shape is that of a minuscule Opuntia with small irregular
cladodes up to 3-5 cm of length. This plant is quite unstable and
have a tendency to revert to common Opuntia shoots.
Chimeras in the the Cactaceae family: Chimaeras of plants
belonging to the Cactaceae family
are very rare and quite unusual in cultivation. The first chimera
+ Hylocalycium (Hylocereus undatus +
Gymnocalycium mihanovichii forma rubra “cv. Red Hibotan”), was
described in cactus & succ .J. of America 1987 61- 4 2,
Recently some other chimerical cactus have been
signalled in internet for example:
