- Stipe (botany)
botany, a stipe is a supportive structure that may be the stem-like part of the thallus of a seaweedor a true leaf stem, as in ferns.
In the case of
ferns, the stipe is only the petiole (or stem) from the rootstockto the beginning of the leaftissue, or lamina. The continuation of the structure within the lamina is then termed a rachis.
This structure is particularly common in
brown algaesuch as kelp.
A stipe is also the stalk-like support of a pistil.(?)
orchids, the stipe or caudicle is the stalk-like support of the pollinia. It is a non-viscid band or strap connecting the pollinia with the viscidium (the viscid part of the rostellum or beak).
