Banana plants are among the largest extant herbaceous plants, some reaching up to 9 m (30 ft) in height or 18 m (59 ft) in the case of Musa ingens.The large herb is composed of a modified underground stem (), a false trunk or pseudostem formed by the basal parts of tightly rolled leaves, a network of roots, and a large flower spike.
The monocots or monocotyledons have, as the name implies, a single (mono-) cotyledon, or embryonic leaf, in their seeds.Historically, this feature was used to contrast the monocots with the dicotyledons or dicots which typically have two cotyledons; however, modern research has shown that the dicots are not a natural group, and the term can only be used to indicate all angiosperms that are not ...
It is estimated that the crown group of Asteraceae evolved at least 85.9 mya (Late Cretaceous, Santonian) with a stem node age of 88–89 mya (Late Cretaceous, Coniacian). Asteraceae is an economically important family, providing food staples, garden plants, and herbal medicines. Species outside of their native ranges can become weedy or invasive.
The APG III system, of 2009 (unchanged from the APG system, 1998), assigns Musaceae to the order Zingiberales in the clade commelinids in the monocots. The oldest fossil evidence of the family is thought to possibly be the Late Cretaceous palynotaxon Spirematospermum chandlerae from North Carolina , unlike most other Spirematospermum species ...
The Liliales are a diverse order of predominantly perennial erect or twining herbaceous and climbing plants. Climbers, such as the herbaceous Gloriosa (Colchicaceae) and Bomarea (Alstroemeriaceae), are common in the Americas in temperate and tropical zones, while most species of the subtropical and tropical genus Smilax (Smilacaceae) are herbaceous or woody climbers and comprise much of the ...
In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles. [1] The cortex is composed mostly of large thin-walled parenchyma cells of the ground tissue system and shows little to no structural differentiation. [ 2 ]
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves , flowers and fruits , transports water and dissolved substances between the roots and the shoots in the xylem and phloem , engages in photosynthesis, stores nutrients, and produces new living tissue.

"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; "A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as:
