Pamianthe on the wiki

Most pollinators are seeking nectar, not pollen, and nectar is usually 
produced from nectaries at the base of the petal.  They get zapped by 
the pollen quite incidentally.  I am not sure what the pollinator is for 
this species, but similar species with long tubes that are night 
blooming and white are pollinated by moths, and there are such 
specialized moths with tongues that can reach that far.

> The wiki account states "The flowering tube is an amazing 20-25 cm long, and must need a very specialized pollinator."
> But the stigma and anthers are in fact close together in this species (as in most amaryllids), and most pollinators should have no trouble moving from one to the other.
> What the extreme length of the flowering tube requires is pollen which can grow from the stigma to the ovary 20-25 cm away.
