No, no they do not. As well as not having a cortex, monocot stems don't have a pith either.
Herbaceous stems do not produce a cork cambium. Herbaceous stems are soft and pliable, composed mostly of primary tissues, while woody stems have secondary growth that includes the production of a cork cambium.
If a stem has cork cambium, it is typically considered woody. The cork cambium (phellogen) is responsible for producing cork cells in woody plants, forming part of the protective outer bark. Herbaceous plants generally lack this cork cambium layer.
Vascular cambium is responsible for secondary growth in a stem.

In a monocot stem, vascular bundles are scattered throughout the stem. However, because the of the lack of vascular cambium, no secondary growth occurs in the monocot stem. As a result of increased cell size, the monocot stem will only increase in height only.
The monocots like the maize produce the cork cambium monocot.
Herbaceous stems do not produce a cork cambium. Herbaceous stems are soft and pliable, composed mostly of primary tissues, while woody stems have secondary growth that includes the production of a cork cambium.
No, monocots do not have a vascular cambium. Vascular cambium is a type of meristematic tissue found in dicots that produces secondary xylem and phloem, allowing for secondary growth in stems. Monocots lack this tissue layer and instead exhibit primary growth throughout their lifespan.

Vascular cambium is responsible for secondary growth in a stem.
The primary source of stem thickening in plants is the vascular cambium, a layer of cells between the xylem and phloem tissues. The vascular cambium is responsible for producing new xylem and phloem cells, which leads to an increase in stem girth over time.
