What is pollinia Caudicle?

The pollinia are solid masses of pollen grains, each attached to a caudicle-an elongate, stalklike structure derived from anther tissue (DRESSLER 1981). The caudicles are, in turn, embedded in the sticky, noncellular material of the viscidium, a structure derived from the stigma (DRESSLER 1981).

What is Pollinium and example?

A pollinium (plural pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Most orchids have waxy pollinia.
