Lophophora v. Jourdaniana Cactus Seeds
There is much mystery surrounding jourdaniana, as it has never been found in the wild, and and its exact origins are still unclear.
Some people suppose Lophophora jourdaniana may perhaps be an hybrid between Lophophora williamsii and Lophophora fricii. Furthermore L. jourdaniana is called Lophophora williamsii var. jourdaniana by some other people. These same people labels Lophophora fricii as Lophophora williamsii var. fricii. This is incorrect because Lophophora fricii is not a variation of Lophophora williamsii, and also the breading of the two different species seems impossible, in fact, the flowers are frequently cleistogame.
It is not possible to fertilize Lophophora jourdaniana with the pollen of Lophophora williamsii, nor with the pollen of Lophophora diffusa and Lophophora fricii. All of this makes Lophophora jourdaniana seed production impossibly difficult and a well guarded secret.
Lophophora jourdaniana is unique in that it is the only Lophophora that retains miniature spines beyond the seedling stage. (See Pic)
