This sub-classification of the genus Pinguicula is derivated from Casper’s monograph (1966), Schlauer (1986), Luhrs (1993), Gluch (1995, 1997) and the world carnivorous plant list maintained up-to-date by J.Schlauer on the carnivorous plant database web site at http://www.omnisterra.com/bot/cp_home.cgi

Subgenera, sections, sub-sections and species have been organised in alphabetical order. Sub-species, forms and varieties have not been included. Species which are subject to debate have not been indicated either. As a complete taxonomic revision of the genus is beyong the scope of this web-site, readers are warmly refered to the litterature on the subject. (see link to recent list of new scientific literature on carnivorous plants (192-2002) by Dr Lubomir Adamec).

Fairly similar upper and lower petals, often forming a falt plane upon flower opening. Wide, short and funnel-shaped corolla tube. Very long spur (longuer than corolla tube).

Section PinguiculaPermalink

Temperate-homophyllous or temperate-heterophyllous growth type. Two-lipped corolla, lower lip larger than upper one. Corolla tube funnel-shaped, of variable length. Spurin the same direction as tube and of variable length.

Section AmpullipalatumPermalink

Tropical homophyllous or heterophyllous growth type. Two-lipped corolla with crenated lobes (rarely entire margins). Corolla tube conical leads to a bag-shaped short spur. Pellate present and clearly visible.

Section micranthusPermalink

Temperate homophyllous growth type. Two-lipped corolla. Central lower lobe crenated and larger than two lateral lower lobes. Conical tube that leads to a short, bag-shaped to conical or cylindrical spur. Pellate protruding outside the corolla.
