wow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
According to Wikipedia, F1 hybrid is:
'[...] seeds/plants or animal offspring resulting from a cross mating of distinctly different parental types. The term is sometimes written with a subscript, as F<sub>1</sub> hybrid. The offspring of distinctly different parental types produce a new, uniform variety with specific characteristics from either or both parents'
If this definition is correct, then Cephalotus follicularis cv. 'Eden Black' x 'Eden Black' does not appear to match this.

Also, the term "hybrid" is reserved for the crossing of two plants NOT of the same species, so any crosses involving selections/cultivars of C. follicularis cannot be described as hybrids, since the genus is monospecific.
Would Cephalotus follicularis "Eden Black" selfed seeds be more accurate a description? To my mind an F1 is a crossing between different parents.
We had been hemming and hawing about this for a while; and a friend of mine whose wife is a botanist suggested that it is correct, while there are others who differ . . .
Yes, that is far more accurate a description. Its quite clear that "hybrid" indicates a cross between two individuals NOT of the same species. There is no such thing as a "Cephalotus hybrid", since it is a nonospecific genus. I believe botany nomenclature is clear on this point. However, feel free to prove me wrong ;-)
For most of the Cephalotus seed, I used a standard 2:3 Knudsen-C with .75 ml/L NAA; other batches were cultured in 25% MS with vitamins at pH 5 -- some with BAP and others without any PGRs whatsoever. The best results to date -- and those shown in the photos -- came from the Knudsen-C. Other growers prefer liquid media for the species; but I have seen no real difference in the results and prefer solid cultures . . .
