Genus: Carnivorous Plants
Aldrovanda
Aldrovanda
Monotypic genus: Aldrovanda vesiculosa, the only aquatic plant in family Droseraceae. Free-floating plant, rootless, with whorled leaves forming small rapid-closure traps similar to Dionaea but only 2-3 mm. Captures zooplankton, insect larvae, and small crustaceans. Considered a "living fossil" — practically unchanged in 50 million years according to fossil records.
Byblis
Byblis
Genus of 7 species of Australian "rainbow plants" and one from Papua New Guinea. Their linear leaves and stems are completely covered with mucilage-secreting glands that glitter with iridescent flashes in the sun (hence the name "rainbow plant"). Morphologically similar to Drosera but in a different phylogenetic position. Flowers are actinomorphic, pentamerous, lilac to purple, with poricidal anthers. Only certain pollinators can vibrate the anthers to release pollen (buzz pollination).
Cephalotus
Cephalotus
Monotypic genus with a single species: Cephalotus follicularis (Albany pitcher plant). Endemic to a small area around Albany, Western Australia. Notable for having TWO types of leaves simultaneously: normal photosynthetic leaves and modified leaves forming small 3-4 cm pitchers with teeth on the peristome and a lid. A canonical example of convergent evolution with Nepenthes and Sarraceniaceae, as they are not phylogenetically related. Highly valued by growers for its rarity and appearance.
Darlingtonia
Darlingtonia
Monotypic genus: Darlingtonia californica, known as "cobra lily" for the hooded appearance of its twisted pitcher. Endemic to mountain bogs in northern California and southern Oregon (USA). Notable for its unusual trapping system: the pitcher has a ventral opening with two "fang" appendages and a translucent dome at the apex. Insects confused by translucent light fall inside. Does not produce its own digestive enzymes — relies on symbiotic bacteria.
Dionaea
Dionaea
Monotypic genus with the most famous carnivorous plant species: Dionaea muscipula (Venus flytrap). Endemic to an extremely small area of the Carolinas (USA), in pine bog savannas. Modified leaves form rapid-closure traps (≤0.1 s) that activate when sensory hairs are touched twice. Dozens of cultivars selected for trap shape, color, and size.
Drosera
Drosera
The most diverse genus of carnivorous plants, with over 200 species distributed on all continents except Antarctica. Known as "sundews" for the glistening droplets of mucilage on their glandular tentacles. Capture insects via leaves covered with sticky trichomes that coil around prey. Extremely variable morphologically: from pygmy rosettes of 1 cm to climbing vines of 1 m.
Drosophyllum
Drosophyllum
Monotypic genus: Drosophyllum lusitanicum (dewy pine). Endemic to the Iberian Peninsula (Portugal, southwestern Spain) and northern Morocco. The only carnivorous plant that grows in dry, well-drained, nutrient-poor soils (Mediterranean maquis) — not in bogs. Leaves produce a sweet aroma that attracts insects, which become stuck to mucilage. Unlike Drosera, leaves coil inward but not around prey. Plants can live 3-5 years and reach 1-1.5 m.
Genlisea
Genlisea
Genus of ~30 species with a unique trapping system: spiral (corkscrew-shaped) traps that capture protists and nematodes from the soil. Underground leaves form an inverted "Y" with two helical tubular arms. Microorganisms enter attracted by chemotaxis but cannot retreat due to internal trichomes. Aerial leaves are simple photosynthetic rosettes. They have the smallest known genomes in flowering plants (some <65 Mb). Distributed in tropical South America and Africa.
Heliamphora
Heliamphora
Genus of 23 species of South American pitcher plants endemic to the tepuis of Venezuela, Guyana, and Brazil (Roraima). Considered evolutionarily the most primitive pitcher plants. Pitchers are simple tubes with a peristome (rim) and a nectar "spoon" at the base of the lid. They do not produce their own digestive enzymes. Live on the isolated summits of tepuis, with high humidity, low temperature, and very poor soils. Great interest among botanists and specialized growers.
Nepenthes
Nepenthes
The most species-diverse genus of carnivorous plants, with over 170 species of tropical pitcher plants. Pitchers hang from tendrils at the tip of modified leaves and contain digestive fluid. Extraordinarily variable in size (pitchers from 5 cm to 50 cm) and morphology. Some highland species trap rats and other vertebrates. Genus of enormous horticultural interest with thousands of registered hybrids.
Pinguicula
Pinguicula
Genus of ~100 species of butterworts with cosmopolitan distribution. The flat, fleshy leaves are covered with mucilage-secreting and digestive enzyme glands. Mainly capture midges, springtails, and moss spores. Wide morphological and ecological variability: from temperate European species (P. vulgaris, P. grandiflora) to Mexican succulents (P. gypsicola, P. gigantea) that are very popular in cultivation for their attractive flowers.
Roridula
Roridula
Genus of 2 species (R. gorgonias, R. dentata) endemic to the Cape Province, South Africa. Shrubby plants up to 1.5 m with linear leaves covered in very long sticky trichomes. Although they capture insects like other carnivorous plants, they do NOT secrete digestive enzymes — insects are consumed by bugs (Pameridea roridulae) that live symbiotically on the plant and whose excrement is directly absorbed. This system of "indirect carnivory" via an intermediary is unique in the plant kingdom.
Sarracenia
Sarracenia
Genus of 11 pitcher plant species endemic to North America. Tubular leaves form erect pitchers with a lid (operculum) that prevents dilution of digestive fluid by rain. Flowers are showy and solitary. Genus with enormous diversity of natural forms, subspecies, varieties, and prolific natural and intergeneric hybridization (×Sarracephora, ×Sarraceniaphor). Widely cultivated by enthusiasts.
Utricularia
Utricularia
The most species-diverse genus of carnivorous plants in the world with ~215 species, and the only one with active vacuum traps. Utricles are tiny bladders (0.5-6 mm) that maintain negative pressure and capture prey in milliseconds via a trap door. Ecologically very diverse: aquatic, semi-aquatic, and terrestrial in bogs. Some barely visible to the naked eye; others with showy flowers. Present on all continents except Antarctica.
