Lobbaea

Lobbaea is a botanical name that has appeared in the scientific literature as the designation of a small genus of flowering plants. The taxonomic status of Lobbaea has been unstable; in many modern classifications the name is treated as a synonym of Lobelia or placed within the broader Lobeliaceae/Campanulaceae alliance, rather than as a distinct genus.

Historically, authors assigned a limited number of species to Lobbaea based on morphological features similar to related genera, but these characters proved insufficient for stable delimitation.

With the advent of molecular phylogenetics, relationships within Lobelioideae have been revisited, and several authorities have proposed consolidating Lobbaea with Lobelia or removing it from current genera altogether.

Consequently, there is little consensus on the number of species that could be attributed to Lobbaea, their diagnostic traits, or their geographic distribution. In contemporary floras, material previously identified as Lobbaea is typically reclassified under Lobelia or other related genera, making Lobbaea a name of limited contemporary use. The status of Lobbaea illustrates broader challenges in genus-level taxonomy, where historical classifications conflict with modern data. Ongoing research in molecular systematics and herbarium reexamination may further clarify whether Lobbaea should be maintained as a separate genus or treated as a synonym of a related group.
