Default reproductive biology of orchids question

Yes, as far as I know, each seed is genetically unique, from one ovule and one
pollen grain. But the big difference in Orchidaceae (Asclepiadaceae also does
it) is that they put their pollen into a lump called a pollenium, which is
carried by the bee/wasp/other pollinator as a single unit, so one pollination
event involves many thousands of pollen grains.
