Angiosperm Morphology: Lactifers in Ficus Vascular Bundles
cross section: Ficus leaf
magnification: 400x
Berkshire Community College Bioscience Image Library
Embedded in the mesophyll are vascular bundles of varying sizes. The bundles are closed, collateral and wrapped in clear parenchymatous bundle sheaths. Xylem occurs to the upper or adaxial surface and phloem to the lower or abaxial surface.
In larger vascular bundles patches of supported sclerenchyma occur above the xylem and below the phloem. Abundant dark staining lactifers produce latex like substances.
Vascular bundles of the petiole and midvein are leptocentric with a ring of xylem surrounding central phloem.
