Q: Pinguicula subgenera and sections
A: The new treatments in 2016
(Lampard et al. (2016), Roccia et al. (2016))
really changed things around in terms of species, but did not
provide guidance on subgenera and sections. So when I rewrote the FAQ in early 2018 I continued to use the old framework that I have used for some time. It is given below, with the
title "Old Framework."
Fleischmann & Roccia (2018) gave a new framework that I'm adopting, but if you're reading this text, that means I have not yet full incorporated it into my FAQ. These things take time.
On each of the pages that follow, I will have a small section called "Changes from 2016-2018", and those will discuss some of the consequences of the
new treatments of the genus, on the genus.
New Framework
- Subgenus Isoloba (Plants with a homophyllous habit)
- Section Ampullipalatum
- Homophyllous Andean species, except P. elongata (ex: P. filifolia)
- Section Cardiophyllum
- A few homophyllous species of Europe (ex: P. hirtiflora)
- Section Isoloba
- Homophyllous species of North America and a little Latin America (ex: P. lutea, P. pumila)
- Section Pumiliformis
- The single homophyllous species P. lusitanica
- Section Ampullipalatum
- Subgenus Pinguicula (Most of the temperate plants with a heterophyllous habit)
- Section Pinguicula
- Many heterophyllous species (ex: P. vulgaris)
- Section Pinguicula
- Subgenus Temnoceras (A mix of temperate and tropical heterophyllous, and homophyllous habits)
- Section Micranthus
- Temperate heterophyllous P. alpina
- Section Heterophylliformis
- Temperate heterophyllous P. elongata
- Section Nana
- A few alpine temperate heterophyllous species (ex. P. villosa)
- Section Temnoceras (A blend of heterophyllous, and homophyllous habits)
- All the Mexican, central American, and most Caribbean species (ex: P. moranensis)
- Section Micranthus
Old Framework

- Section Cardiophyllum
- A few homophyllous species of Europe (ex: P. hirtiflora)
- Section Heterophyllum
- Many heterophyllous species of Mexico (ex: P. acuminata)
- Section Isoloba
- Many homophyllous of North America, Mexico, and one of Europe (ex: P. lutea, P. pumila, P. lusitanica)
- Section Agnata
- Subgenus Orcheosanthus
- Section Crassifolia
- A few heterophyllous species of Mexico (ex: P. ehlersiae)
- Section Longitubus
- Several heterophyllous species of Mexico (ex: P. laueana)

- A few heterophyllous species of Mexico and Central America (ex: P. mesophytica)
- Section Crassifolia
- Subgenus Pinguicula
- Section Pinguicula
- Many temperate heterophyllous, with loose hibernacula (ex: P. vulgaris)
- Section Pinguicula
- Subgenus Temnoceras
- Section Ampullipalatum
- Several homophyllous species of South America (ex: P. chilensis)
- Heterophyllous P. elongata, probably misplaced
- Section Micranthus
- Several temperate heterophyllous, with affixed hibernacula (ex: P. alpina)
- Section Microphyllum
- A few heterophyllous species of Mexico (ex: P. nivalis)
- Section Nana
- A single temperate heterophyllous (P. villosa)
- Section Temnoceras
- A few homophyllous species of Mexico and Central America (ex: P. emarginata)
- Section Ampullipalatum
