These two pictures show examples of the fruits of the 'Bizzario' citrus chimera. In botany a chimera is a plant where two varieties, or even species, have combined and intermingled to form a plant that has some parts of one form and some of the other. Volkamer shows in the pictures above the two types of fruit that can appear. These are the Bitter Orange and Citron. Other pictures show intermediate fruit that have some areas of each type.
Bizzario is still cultivated in some specialist citrus collections. It can only be propagated by budding, grafting or cuttings, as it will not be reproduced from seed.
The only plant chimera I have ever seen is Laburnum+Cytisus, a small tree that looks like a normal Laburnum but randomly produces shoots and flowers of Broom (Cytisus).
