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.
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.
Carnivorous plant can have simple traps or elaborate traps. Whatever works, works for them.
Benefiting from trapped prey is the hallmark of true carnivory. How do we know when a plant benefits?
There are costs to carnivory that plants must pay. These costs can be high and not all carnivores are all carnivorous all the time.
Drosera, Dionaea, Aldrovanda, Nepenthes, Drosophyllum, and Triphyophyllum are all closely related.
The closest relatives of Nepenthes are sticky-leaved carnivores and plants that evolved to become non-carnivores.
The Drosera phylogeny goes so far back in the dim past that we cannot tell how they diverged from their closest relatives.
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 happen in the wild and contribute to the evolution of new species.
Many Drosera species kill their own pollen if it lands on their stigma. This is actually quite common among flowering plants.
In the Lamiales there is a progression of trap types from sticky traps to the most complicated of carnivore traps.
The Utricularia phylogeny shows the itinerary a world traveller.
The next time you eat a kiwi fruit, you will be eating the fruit of a close relative of the Ericales carnivores.
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.
There are at least 11 species in the Drosera indica complex. Who knew?
Why is it that our view of the Drosera peltata species complex keeps changing and may continue to change?
This complex is in desperate need of an in-depth study.
