pseudostem
Noun
Meaning
pseudostem (plural pseudostems)
(botany) A false stem made of the rolled bases of leaves.
The pseudostem of the banana can be several metres tall.
Examples
A stem develops which grows up inside the pseudostem, carrying the immature inflorescence until eventually it emerges at the top.sfn Each pseudostem normally produces a single inflorescence, also known as the "banana heart".
Characteristics Members of the family are small to large herbaceous plants with distichous leaves with basal sheaths that overlap to form a pseudostem.
The leaf stalks ( petioles ) are expanded at the base to form sheaths that are tightly wrapped together to form the pseudostem.
The base of the petiole widens to form a sheath; the tightly packed sheaths make up the pseudostem, which is all that supports the plant.
As new growth occurs in the centre of the pseudostem the edges are forced apart.sfn Cultivated banana plants vary in height depending on the variety and growing conditions.
Usually this is done by carefully removing a sucker (a vertical shoot that develops from the base of the banana pseudostem) with some roots intact.
