    I've been looking for N. x'Savannah Rose' recently and noticed that a lot of people don't know the parents...then I noticed in the CP database that N. x'Emmarene' is synonymous with N. x'Savannah Rose'. Are these two neps one and the same?

    Hi Vertigo,
    Nepenthes emmarene is a hybrid of ventricosa x khasiana. There's quite a few plants out there, because germination was high. 'Savannah Rose' is a cultivar from the cross, noted for its reddish pink color. Clyde and Bruce named their crosses using orchid breeders logic. All the seedlings were given a grex name, and selected individuals were given cultivar status. According to the rules (available at the ICPS plant cultivar registry), only orchids are allowed to have the entire cross given a name, so they were doing things incorrectly-like the Japanese. Carnivorous plants, like roses or hibiscus, or any other cultivated plant, are only given cultivar status-that is, select individuals from the grex are registered, usually based on some horticulturally desireable characteristic.
    Nepenthes hybrid nomenclature is a mess. You almost have to memorize the crosses and where they're from to know what you've got.
    Hope this is helpful.

    Thanks Trent, that does clear things up a bit. Too bad the ICPS and a japanese society can't get together and form more of a worldwide set of rulings. I know that with the Dionaea muscipula cultivars that things started turning into a mess through translation and basically ignorance. That and the random places creating plants specifically to sell to nurseries and giving them names so that the buyer would know what traits the plant has, ex. Dionaea m. Vigorous.

    Actually, the way the Japanese name their Neps does make sense. Each grex is given a name. Example: the cross of N. thorelii x N. maxima. There's Rokko, Balmy Koto, etc. etc. There are differences among them.
    The Victorian crosses were a little screwy. Take the cross of mirabilis x hookeriana. If the seedlings produced red pitchers, the were coccinea, others would be henryana, or whatever name they wanted to use.

    Yeah, you're right, that is pretty confusing. With so much variability in offspring through pollination and seeds the amount of names that one could use for one cross could be insane. We should really be glad that neps aren't more like fancy guppies, no one would ever be able to keep track of the names of them and all would have to be reproduced through vegetative means.
