Cytology

The diploid chromosome count of this species is 2n = 40,[6] or 2n = 38.[7]

The sphingophilous flowers are fragrant during the night.[8]

Etymology

It is named after Léon Humblot, a French orchid collector.[9]

Physiology

Floral fragrance

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]

Chavicol , the main component of the floral fragrance of Angraecum leonis[8]
