- However, the flower is constructed in such a way as to make the surface almost impossible to cling to, with smooth, downward-pointing hairs; the bees commonly slip and fall into the fluid in the bucket, and the only navigable route out is a narrow, constricting passage that either glues a " pollinium " ( a pollen sack ) on their body ( if the flower has not yet been visited ) or removes any pollinium that is there ( if the flower has already been visited ).
