In 1841, Albius invented a method to quickly pollinate the vanilla orchid using a thin stick or blade of grass and a simple thumb gesture. Using the stick or grass blade, field hands lift the rostellum, the flap that separates the male anther from the female stigma, and then, with their thumbs, smear the sticky pollen from the anther over the ...
Despite its logistical challenges, hand pollination was judged the most likely method to achieve fertilization and increase genetic exchange between nursery and wild individuals. Controlled propagation is used to reintroduce seedlings, since previous outplantings have an 80+% survivorship; [ 3 ] as the plants flower only once after many years.
A few years later in 1841, a simple and efficient artificial hand-pollination method was developed by a 12-year-old slave named Edmond Albius on Réunion, a method still used today.

In order for pollen to affix to animal bodies, a tryphine coating is usually present in zoophilous pollen to achieve an adhesive pollen grain. [1] Visual attractants of monocot flowers mainly come from the coloration of tepals.
