Solenocentrum

Solenocentrum is a term used in botany, specifically in the study of orchids (family Orchidaceae). It refers to a particular arrangement of the pollinia within the flower.

Specifically, in a Solenocentrum, the pollinia are arranged in a column with the caudicles (the stalks that connect the pollinia to the viscidium) running through a channel or cavity within the column. This channel guides the caudicles, ensuring proper placement of the pollinia onto a pollinating agent, such as an insect. The term describes the physical structure that facilitates targeted pollination. This structure is important for the orchid's reproductive success. The presence of a Solenocentrum is a diagnostic characteristic for identifying certain genera and species of orchids.
