Hint: It is a genus of about 120 species of trees and succulent shrubs and is the only monocot, which has been shown to also have secondary growth in roots.
Complete answer:
Secondary growth occurs by the development of irregular vascular or cork cambium or formation of accessory cambia is called anomalous secondary growth.
Dracaena is a genus of about 120 species of trees and succulent shrubs and is the only monocot, which has been shown to also have secondary growth occurs by the development of irregular vascular or cork cambium in roots.
Palm trees are monocots that heighten quite tall and thick, yet they lack "normal" secondary growth. Dracaena is a monocot but not a true palm, they lack peripheral secondary thickening meristem. Therefore, the abnormal/anomalous secondary growth occurs in Dracaena.
Additional information:
-Ancestral monocots lost their secondary growth and their stele has changed during a way it couldn't be recovered without major changes that are impossible to occur.
-Monocots either haven't any secondary growth, as is that the ancestral case, or they need an "anomalous secondary growth" of some type.
- In the case of palms, they enlarge their diameter in what's called a kind of secondary growth or not counting on the definition given to the term.
-Some monocot stems increase in diameter thanks to the activity of a primary thickening meristem, which springs from the apical meristem.
So, the correct answer is ‘Dracaena’.
Note: Palm trees increase their body’s diameter due to division and growth of parenchyma cells, whichever is known as "primary gigantism" because there's no production of secondary xylem and phloem tissues, or occasionally "diffuse secondary growth".
