Two different forms of this species exist. The form native to the Comoros is considerably larger and nearly twice as big as the one native to Madagascar.[2][3][4][5]
Cytology edit
The diploid chromosome count of this species is 2n = 40,[6] or 2n = 38.[7]
Ecology edit
Pollination edit
The sphingophilous flowers are fragrant during the night.[8]
Etymology edit
It is named after Léon Humblot, a French orchid collector.[9]
Physiology edit
Floral fragrance edit
The floral fragrance is primarily composed of chavicol (70%), followed by benzyl salicylate (7.3%), benzyl benzoate (5.5%), methyl nicotinate (5.3%), as well as many more compounds in smaller quantities.[8]

It can be successfully cultivated in intermediate temperatures.[10] It can be mounted on cork and bark, but it can also grow potted in bark pieces. It should be grown in shade to semi-shade.[2]
