What does pedicellate mean?
Pedicellate is a technical adjective meaning that something has a small supporting stalk, or pedicel. It is especially common in descriptions of plant structures, fungi, and pollen, as well as certain animal structures. A pedicellate pollen grain, for example, is one attached to or associated with a slender stalk rather than being entirely sessile, or stalkless. The contrast between pedicellate and sessile is an important one in scientific description because the presence of a stalk can affect how a structure is positioned, moved, or dispersed. Although the word may sound elaborate, it follows a straightforward pattern: pedicel supplies the noun, while the suffix -ate forms an adjective describing the presence of that feature. It is therefore most useful in specialist writing rather than ordinary conversation.
adjectiveHaving a pedicel, especially a small stalk supporting a flower, spore, pollen grain, or other structure. The term is chiefly used in botanical, zoological, and palynological description.
- Having a small stalk or pedicel; borne on a pedicel.
"The microscope revealed several pedicellate pollen grains scattered across the slide."
"Several pedicellate spores were visible under the dissecting microscope."
"Unlike the sessile variety, the pedicellate flowers sway gently in the breeze."
Pedicellate ultimately means “little-footed”: its structures stand on tiny stalks, just as a pedicel was named from the Latin diminutive for foot.

Where does pedicellate come from?
The word comes from New Latin pedicellatus, formed from pedicellus, a diminutive of Latin pediculus, itself derived from pes, meaning “foot.” The diminutive thus literally refers to a “little foot,” a fitting image for a small stalk that supports another structure. Related English words include pedicel, the botanical stalk, and pedicle, a smaller anatomical projection.
How pedicellate is actually used
This is a specialized descriptive term used most often in botany, mycology, zoology, and palynology. It is more precise than the general term “stalked” when the stalk is specifically a pedicel.
Easily confused with pedicellate
A pedicel is the slender stalk that supports a flower or other structure, whereas pedicellate is the adjective describing something as having or being borne on such a stalk.
