Carnivory
What are Carnivorous Plants?
Carnivorous plants are just plants with a special set of characters that allow them to use animals for food. There is nothing they do that some other plant or plants cannot do. It is the package of traits that define what is carnivorous and what is not.
Murderous Plants
Many plants kill animals in a body present way. That does not mean they are carnivorous. Or semi-carnivorous. Or proto-carnivorous. Or whaterver-carnivorous. They are just murderous.
Trapping Mechanisms
Carnivorous plant can have simple traps or elaborate traps. Whatever works, works for them.
Digestion & Absorption
Benefiting from trapped prey is the hallmark of true carnivory. How do we know when a plant benefits?
Costs of Carnivory
There are costs to carnivory that plants must pay. These costs can be high and not all carnivores are all carnivorous all the time.
Relationships and Evolution
Evolution of the Caryophyllales Carnivores
Drosera, Dionaea, Aldrovanda, Nepenthes, Drosophyllum, and Triphyophyllum are all closely related.
Nepenthes Phylogeny
The closest relatives of Nepenthes are sticky-leaved carnivores and plants that evolved to become non-carnivores.
Drosera Phylogeny
The Drosera phylogeny goes so far back in the dim past that we cannot tell how they diverged from their closest relatives.
Drosera Chromosomes
Drosera has a type of chromosome that is very uncommon in nature. That plus the usual suspects of chromosomal dynamics helped create this very diverse genus.
Drosera Hybrids
Drosera hybrids happen in the wild and contribute to the evolution of new species.
Self-incompatibilty
Many Drosera species kill their own pollen if it lands on their stigma. This is actually quite common among flowering plants.
Evolution of the Lamiales Carnivores
In the Lamiales there is a progression of trap types from sticky traps to the most complicated of carnivore traps.
Utricularia Phylogeny
The Utricularia phylogeny shows the itinerary a world traveller.
Evolution of the Ericales Carnivores
The next time you eat a kiwi fruit, you will be eating the fruit of a close relative of the Ericales carnivores.
Evolution of the Oxalidales Carnivore
Cephalotus is the only species in its family. It's closest relative is Oxalis.

Compendium of all publish carnivorous plant names with notes on the validity of the names.
Drosera indica Complex
There are at least 11 species in the Drosera indica complex. Who knew?
Drosera peltata Complex
Why is it that our view of the Drosera peltata species complex keeps changing and may continue to change?
Drosera spatulata Species Complex
This complex is in desperate need of an in-depth study.
