Torulosa, hollywood juniper, and kaizuka are the same plant. Foemina is different. Regarding the former, kaizuka is the legitimate name under the ICNCP. torulosa is illegitimate because the plant already had a legitimate cultivar name. You can't give an old cultivar a new name. Second, latinized cultivar names are illegitimate if given after 1959. Torulosa is based on Latin torus.
Hollywood juniper is more like a common name apparently it is commonly planted in Los Angeles area. It's also very commonly planted here but that doesn't mean I can call it San Antonio juniper, at least not under the rules of the ICNCP. I agree that it is often listed as torulosa, I disagree if you're saying that means the two epithets are equally valid.
Hate to disagree with you but foemina did replace torulosa as the varietal name in the trade but they still
are cut from the same mother plants that each nurseryman used no matter which label he slapped on it.
Though some try to treat them as "different sub-strains" or some other explanation. I have actually seen potted "lots" being labeled
as both depending on which part of the country they were being shipped to.
And yes "Kaizuka" is the
orignal, and I feel correct, varietal designation. However, "Elegans Superba" (1870) is completely
unknown now but was the
origninal/proper designation for "Pride of Mobile" azalea. I fear that, much as many
have already, "Kaizuka" will end up as a historical footnote.
