About natural hybrids, when you make an hybrid, you are sure you have, for instance, C. skinnerii x C. arantiaca, only once of the both parents. When nature coss, you can have several crosses made. We have in Rio de Janeiro C. xvenosa = C. forbesii x. C. harrisoniana, and you find xvenosa very close to forbesii (only with some color difference) and xvenosa almost harrisoniana (some labelum difference), depending of how close they are of forbesii or harrisoniana population. None of them are pure, primary hybrids of C. forbesii and C. harrisoniana, and when you make the cross, you never have plants with the characteristics that you find in the wild plants.
