Euphorbia millii (#32),
Cereus (#27 и #28),
Gymnocalycium (#22, #23),
Here we have selected for you some photos of crested Opuntia.
Cristate shoots appear as a result of the flattening of the developing stem. Apparently the occurrence has a chimerical nature: caused by the gene difference of the tissues participating in the meristem development. If the cell division is not coordinated the appearance of cristate shoot is become possible. The shoot flattening is abnormal
for majority of plants.
But for Opuntia flat stem segments are normal (as well as for Rhypsalis and other plants stems of which functioning as leaves).Flat, disk-like shoots are typical for them. Such the effect of a "controlled" cristate is not very common. However there are traditional crested specimens with overgrowth caused by the meristem divergence in addition to the typical stem flattening.
