Varieties: There are no varieties in the proper sense, but there are many clones which can differ in the stem type, colour, fruit shape, skin thickness and scale expression. There are however two different species, H. undatus which has white flesh and H. polyrhizus which has red flesh. There are also several other fruiting cactus genera that are called 'pitaya' one of these is Selenicereus megalanthus which has smaller fruit with yellow skin, white flesh and clusters of spines on the fruit that brush off when ripe.
