The evolution of cacti
Actually in the genus, the cultivar Pereskia aculeata 'Godseffiana' is
rather attractive with its peach colored leaves and a popular house plant. http://www.csdl.tamu.edu/FLORA/fa01/fa01087.jpg I really wasn't referring to the most primitive genus Pereskia in the Cactaceae but rather to such shrubby genera as Leptocereus and Acanthocereus being ancestral to the better known succulent types. Iris Cohen wrote in message ... I don't agree with your assessment of the Cactaceae. The most primitive genera are of woody shrubby species that gave rise to various genera of vining, epiphytic and thick stemmed globose to columnar desert types. The primitive genera are rarely grown by succulent plant hobbyists but they are of the most interest to taxonomists. I grew a Pereskia once out of curiosity. Not a very attractive houseplant. However, it was interesting to see the various traits, like thorns & areoles, and compare them with the same traits on advanced Cactaceae.
