Cymbidium pseudobulb

Pseudobulb is an abnormal stem produced at the node of two leaves, which is the storage organ of water and nutrients. Pseudobulb is a unique organ of Orchidaceae and is mainly found in epiphytic orchids. It may be composed of single or multiple evergreen leaves or deciduous internodes. The pseudobulbs of some orchids look ordinary, just like the stems of other leafy plants, while others, such as Bulbophyllum, have large spherical pseudobulbs with pseudobulbs at the base of every one or two leaves.

The abnormal stem of Orchidaceae, usually ovoid to oval, fleshy, green or sometimes of other color, where nutrients and water are stored. Orchids often grow on trees or rocks, and terrestrial orchids are often grown in places with good drainage, so special storage tissues are needed to ensure the continuous supply of nutrients and water. Pseudobulbs are the storage tissues of orchids that adapt to this particular habitat, and the green ones can also operate photosynthesis. It is usually jointless, that is, it contains only one Internode, apical leaves, less with 2 to several nodes, leaves on nodes. Pseudobulbs are usually connected by rhizomes.
