|Pinguicula moranensis in the Bristol University Botanical Gardens Greenhouses|
The leaf can bend itself slightly through thigmotropism to bring more glands into contact with the prey. Once the prey is entrapped the sesile glands release digestive enzymes which to digest the prey breaking down the digestible parts of its body into liquids which are then reabsorbed by the leaf through cuticular holes leaving only the chitin exoskeleton behind.
The etymology of the genus name Pinguicula comes from the Latin pinguis which mean fat because of the buttery texture of the leaves while the specific name moranensis refers to its type location, Mina de Moran in the Sierra de Pachuca. This is where the three botanists Humbolt, Bonpland and Kunth collected specimens of the plant during an expedition in early 1800s. However, in 1999 a Mexican botanist S. Zamudio collected specimens in the same area and noted that the plants he had collected did not share the original description given by Humbolt, Bonpland and Kunt
Further investigation based on the travels of the earlier expedition led Zamudio to conclude that the plants collected by Humbolt, Bonpland and Kunt were most likely from an area called "El Puente de la Madre de Dios" in the Mexican state of Higaldo. He confirmed this by finding matching specimens of the plants in that area.
So it appears that due to some mix up these plants were misnamed. In the end Zamudio published his findings as a variation of Pinguicula moranensis under the name Pinguicula moranensis var. neovolcanica.

- I am using the taxonomical classification system used by ITIS (Intergrated Taxonomic Information System). I have decided to use this system in order to avoid confusion as well as because it offers a comprehensive hierarchy from kingdom right through to subspecies whereas other sources only go as far as order or provide the names of some of the higher taxonomical ranks but only indicate "unclassified" rather than providing the rank.
- When and where possible I will endeavour to include alternatives classifications although I may limit this to occasions where an opportunity arises to discuss the reason for the different classifications.
