laticifer
Very Low (Specialist)Technical/Scientific
Definition
Meaning
A specialized plant cell or duct that produces and contains latex.
Any cellular structure (e.g., vessel, tube, or cell) within the vascular system of certain plants that synthesizes and transports latex, a milky fluid often containing resins, alkaloids, or proteins.
Linguistics
Semantic Notes
The term is used almost exclusively in botany and plant anatomy. It refers to both the individual cells (non-articulated laticifers) and the elongated, often branched tube systems (articulated laticifers) formed from multiple cells.

Examples
By Part of Speech
adjective
British English
- The laticiferous tissue was examined under the microscope.
American English
- Laticiferous plants were catalogued in the survey.
Examples
By CEFR Level
- Some plants have a white juice called latex inside special cells.

Learning
Memory Aids
Mnemonic
Think of 'LATEx' inside a 'CELL' or 'conduIT' = LAT(EX)-I-CIF-ER.
Conceptual Metaphor
A laticifer is like a factory pipeline within the plant, both manufacturing and transporting its sticky, milky product.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'лактофер' (lactoferrin, a protein).
- The '-fer' suffix relates to 'bearing/carrying' (from Latin 'ferre'), not to 'iron' (as in 'феррум').
Common Mistakes
- Misspelling as 'lactifer' or 'lacticifer' (confusion with milk/lactose).
- Incorrect pronunciation with a hard 'c' (/k/) instead of a soft 'c' (/s/).

FAQ
Frequently Asked Questions
No, laticifers are found in many plant families, including poppies, figs, spurges (Euphorbiaceae), and dogbanes (Apocynaceae).
Individual laticifers are microscopic. However, when you break a dandelion stem and see the white milky sap, you are seeing latex released from many ruptured laticifers.
Articulated laticifers are formed from a series of connected cells where the end walls break down. Non-articulated laticifers develop from a single cell that elongates and branches without forming cross-walls.
No, while often white or creamy, latex can be yellow, orange, or even colourless, depending on the plant species and the chemical compounds it contains.
