All About Cultivars and Hybrids
Platycerium cultivar and hybrids are common among platyceriums, and they account for many of the problems in species definition. When you mix the spore from two different species of platycerium, sometimes you get a new plant which tends to show the traits of both of its parent species and they may or may not be sterile. This author argues that to be a new cultivar or hybrid, it should be able to propagate the new characteristics, otherwise it will be just a sport of the mixture and possibly short lived. In many cases, a cultivar (cultured variety) is a hybrid, but not all cultivars are hybrids. Many cultivars are "mutations" occurring in nature but pure to the species. Cultivars and hybrids should be able to propagate a true duplicate.
Hobbyists have created many new hybrids, and probably some new ones have been created in nature through the breakdown of isolating mechanisms. Some times just growing two different species in the same greenhouse will result in a new hybrid. Then when you cross the spore from two different cultivars of a species, you may get a new cultivar, or a new hybrid. It is wise to consider it a cultivar until more experience is obtained growing new pups or sporelings. This cross index is designed to identify the common and known crosses or hybrids. Then of course, when you start crossing spore from two hybrids, you can possibly get another new hybrid. And the chain continues endlessly as is the case in many flowers.
If you develop a cultivar/hybrid, it is wise to send pups to other growers in other parts of the state or country to see if they maintain the same growing characteristics as your cultivar/hybrid. Or are your findings a product of your environment? If the same characteristics continue to appear, and its pups display the same characteristic, then we can start to build an argument for a new cultivar or hybrid. But this takes years and should not be done hastily.
To use this cross index, identify the first species in the left column and move right until you find the cross and t6he name of the hybrid when known.

The above list is not intended to be the final word on hybrid identification. Until more complete DNA testing is available, the above list is more a guide than a final definition.
