pseudobulbeja

Pseudobulbeja is a term used in informal botany to describe plants that possess bulb-like storage organs yet are not classified as true bulbs. It is not an official taxon and has no formal type specimen. The term circulates mainly among horticulturists and in online glossaries as a descriptive label rather than a formal classification.

Etymology and scope: The name blends "pseudo-" meaning false with a root resembling "bulb." It is applied broadly to plants across diverse genera that exhibit a conspicuous, swollen storage structure near the base of the stem, which stores water and nutrients.

Morphology and ecology: Pseudobulbeja-like plants typically have one or more swollen storage organs at or just below the ground level, packed with tissues for water retention. Leaves usually arise from the crown, and growth forms range from compact terrestrial to epiphytic. They are commonly discussed in the context of orchids and other tropic-subtropical taxa, though the term is not taxonomically binding.

Taxonomic status and usage: Because pseudobulbeja is not governed by a codes of nomenclature, there is no universally accepted definition or exemplar. It is used informally to highlight morphological convergence rather than to assert evolutionary relationships, and some critics argue it risks conflating distinct lineages.
