Pinguicula elizabethiae combines broad carnivorous leaves with a densely packed resting rosette. Its most useful identification features include hairs that are easy to overlook when attention is focused on the flower.
Identity and distinguishing features
Sergio Zamudio described the species in 1999 from the Moctezuma and Tolimán canyon system of Hidalgo and Querétaro, naming it in memory of botanist Elizabeth Argüelles. Broadly rounded flower lobes resemble those of P. cyclosecta and P. colimensis, but the complete combination of leaves, hairs and habitat differs. Original publication.
Summer leaves narrow gradually towards the base, where long multicellular hairs form an interlacing network. The margins turn slightly inward. Resting leaves are numerous, small and spoon-shaped, also with conspicuous long hairs. Flowers in the original description measure 36–46 mm including the spur; the tube is short and the spur much longer. Original description and comparison table.
The hairs should be documented in photographs without pulling the rosette apart. A seasonal change in leaf size is valuable information; a name assigned solely from a pink flower is much less secure.
Canyon habitats and variation
The original account records north- or northeast-facing shale slopes in submontane scrub at 1,000–1,600 m, associated with mosses, ferns and Selaginella lepidophylla. It reports August–September flowering observations and a wider July–October period communicated by another observer. Zamudio (1999).
Fernando Rivadavia’s July 2006 Tolimán exploration found plants on calcareous seeps, humid canyon banks and another, barely moist rocky slope. Flowering plants and spent capsules were present. Flowers varied from pink and purple to lilac and very pale pink; spurs could be straight or curved. These are dated field observations, not named varieties or proof that every population behaves identically. Tolimán field report.
The descriptions of shale and calcareous deposits need not be flattened into one substrate recipe. They show why a habitat record should specify both the underlying rock and the actual surface occupied by the plant.
Care through the two rosettes
Oliver Gluch recommends an airy medium, good air circulation and sparse watering during the resting period. His account also notes the distinction between the published shale habitat and calcareous deposits in Tolimán. Gluch’s species and cultivation account.
Our practical interpretation is to reduce watering as the compact rosette develops, while watching the individual plant and the medium. The northern-hemisphere months in a European growing account should not be copied directly into an Australian calendar. A small resting rosette should not automatically be treated as a failing summer plant and watered more heavily.
Propagation and remaining questions
No species-specific propagation success rate was verified for this draft. Keep any leaf-cutting or seed trial labelled as an experiment, with the parent accession recorded. The long basal hairs also make rough leaf removal a poor default handling choice.
Before publication, the profile needs authenticated seasonal photographs and their permissions. Field colour variation does not establish cultivar identity, and nothing in this account confirms a particular nursery clone or current availability.
