Another cross-genus hybrid is that between Green-winged Orchid (Anacamptis morio) and Early-purple Orchid (Orchis mascula) which is from a differing genera (although both are in the same family). The resulting cross is called X Anacamptorchis morioides. It too is shown in a green square on the forbidden diagonal. There are thus no species belonging to the Anacaptis Genus which do not (at the moment) hybridise (with something).

Two others occupy the same green square, for both are hybrids with Heath Fragrant Orchid (Gymnadenia conopsea):
The first of these being with Pyramidal Orchid (Anacamptis pyramidalis) yielding the hybrid X Gymnanacamptis anacampti
The second being with Early Marsh-orchid (Dactylorhiza incarnata), the result having no other name than Dactylorhiza incarnata x Gymnadenia conopsea.

There is, however, another Orchis species that does indeed cross hybridise with another Genus, that of Orchis mascula (Early Purple Orchid) which crosses with Anacamptis morio (Green-winged Orchid) to produce the cross-genus hybrid X Anacamptorchis moroides. This hybrid is shown in a green square, occupying a position on the forbidden diagonal of the chart which is just a convenient place to put it.

The Helleborines are in two genera, the Cephalanthera, and the Epipactis, the main difference between the two being that Cephalanthera species have flowers that do not fully open so the un-spurred lip is often hidden whereas the un-spurred lips of Epipactis species are easily visible.
