Simile Humano species pollinating the Multistamen

Apparently, because of the rarity, Multistamen is very valuable for simile humano, so they carefully monitor that in the process of pollination each plant produces the maximum amount of seed material, for which they constantly massage and stroke it`s seed sacs and stimulate the pistils. When being stimulated enough, pistils throw off clouds of pollen (like most of the local plants do, actually).
