The third installment of the Infrequent Plant Profile Project, a project I began a while ago at my old livejournal account. I know that I will not stick to a schedule if I designed one, so I choose to make this project informal and infrequent. These will be profiles of plants that interest me and of the circumstances of their original description.

It is surprising that a species could have been overlooked by so many botanists working in the southeastern US until 1957 when P. primuliflora was formally described. This just goes to show how important extensive research into the flora of a region is. It also provides us with an example of how rigorous research, a large sample size, and careful measurements of morphological characteristics of closely-related species can reveal unique populations worthy of recognition at the rank of species or subspecies.
Today, P. primulaflora is one of the most widely-cultivated Pinguicula species and can be found frequently in hardware stores, often in the appropriately-named "Death Cubes." It is a prolific species, producing many rooted clones where leaves touch the soil substrate. Many cultivars of this species exist, including a spectacular double-flowered variety (pictured above)
