This species, to my knowledge, has no genetic alba form. There are two colour forms, though - the regularly coloured form and a plain green form (often called "var. album"). The latter is favoured in breeding due to the regular form "muddying" colours in its offspring.

There is something rather unusual about this species and its effect on alba genetics in hybridising. Andy Easton of NHO has noted through his work with Cymbidiums that if this species is crossed with an alba, the F2 generation does not obey the expected Mendelian ratios (i.e. 25% albas) when crossed to another genetic alba - instead the count of resulting alba seedlings is incredibly low. Ratios return to normal in the F3 generation, however.
