A pistil may consist of one carpel (with its ovary, style and stigma); or it may comprise several carpels joined together to form a single ovary, the whole unit called a pistil. The gynoecium may present as one or more uni-carpellate pistils or as one multi-carpellate pistil.
Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe.

A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of stigmatic papillae , the cells of which are receptive to pollen.
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals.
Bergenia crassifolia is a species of flowering plant of the genus Bergenia in the family Saxifragaceae. Common names for the species include heart-leaved bergenia, [1] [2] heartleaf bergenia, leather bergenia, [2] winter-blooming bergenia, [3] elephant-ears, [1] elephant's ears, [2] Korean elephant-ear, [4] badan, pigsqueak, [3] Siberian tea, [2] and Mongolian tea.
Three unripe ears (of barley, wheat, and rye): each has many awns (bristles) An ear is the grain-bearing tip part of the stem of a cereal plant, such as wheat or maize (corn). [1] It can also refer to "a prominent lobe in some leaves." [2] The ear is a spike, consisting of a central stem on which tightly packed rows of flowers grow.
The pistil, finally, commonly terminates in a style and a stigma that is not decurrent. The fruit is dry and dehiscent, when it is a capsule it shows loculicidal dehiscence. Regarding the interaction between pollen and pistil, pentapetalous plants have a gametophytic incompatibility system based on the RNAase system.
