  Nepenthales: Droseraceae & Nepenthaceae   (Site not responding. Last check: 2007-10-21)
Nepenthales includes the Nepenthaceae (Asian pitcher plants) and the Droseraceae (flytraps & sundews).
At the bottom of the trap is a pool of fluid containing digestive enzymes, where the hapless insects drown and are digested for their nutrients.
Unlike other carnivorous plants in the Nepenthales, Nepenthes traps are reusable, and may trap many victims in the same pool of digestive fluid.

However, the group is not well defined from a structural point of view and the three families are treated in various ways in other classification systems.
Most angiosperms secure this fundamental element from the soil and, if it is not available, the niche is not occupied.
Taxa of the Nepenthales have evolved ways around the nitrogen problem, i.e., extracting it from animals - mostly arthropods - via clever structural and biochemcial innovations.

There is good reason to expect that many of the groups are para- or polyphyletic, and a number of alternative classifications have arisen.
Sarraceniales - this order is empty in ITIS; its contents appear to now be included in the Nepenthales.
Umbellales - this order is empty in ITIS; most of its contents appear to have been moved to the Apiales.

Takhtajan (1997) retains the ordinal distinction but moves both this order and what Cronquist termed the Nepenthales to a position adjacent to the Ericales in the Theanae rather than near the Violales.
As for the Nepenthaceae, Lindley assigned these to the order Nepenthales and placed them next to the Aristolochiales in an artificial group that he soon abandoned.
In 1846, Lindley reluctantly abandoned even the Nepenthales and positioned them in the Euphorbiales next to the ericoid family Empetraceae.

The leaves are usually in a basal rosette, and both leaf surfaces are generally covered with sticky gland-tipped hairs and sensitive tentacles that entrap insects.
The size range alone is quite remarkable, from probably the smallest individual flowering plant, the watermeal (Wolffia; Arales), at less than 2 millimetres (0.08 inch) to one of the tallest angiosperms, Australia's mountain ash tree (Eucalyptus regnans; Myrtales) at about 100...

Carnivory was found not to be a prerequisite to reach full maturity or to produce flowers and seeds.
peltatum is an intriguing aspect of carnivorous plant evolution within Nepenthales, a flowering plant order that contains four different carnivorous plant families, viz.
Besides plumbagin and similar quinones, which are characteristic for Nepenthales, the plant contains naphthylisoquinoline alkaloids (Bringmann et al., 1998), which are so far known only from Dioncophyllaceae and Ancistrocladaceae.

 Caryophyllales   (Site not responding. Last check: 2007-10-21)
Cronquist gave the Polygonaceae and Plumbaginaceae their own orders, which together with his Caryophyllales made up thesubclass Caryophyllidae.
TheDroseraceae and Nepenthaceae (including the Drosophyllaceae) made up the order Nepenthales, together with the Sarraceniaceae, andthe remaining families were placed among the Violales, both of which were includedamong the Dilleniidae.
Two other families are included in the Caryophyllales, which do not fall into either of the above groups:

 Re: If all plants are autotrophic, why are venus flytraps plants?
Autotrophs can be defined as organisms that obtain their energy from light or inorganic chemicals.
Venus flytrap classification: Kingdom: Plantae Phylum: Anthophyta or Magnoliophyta (flowering plants or angiosperms) Class: Dicotyledonae or Magnoliopsida (dicots) Order: Nepenthales Family: Droseraceae Genus: Dionea or Dionaea Species: Dionea muscipula (Note that muscipula is termed the specific epithet, not the species) Search google.com for many websites on venus flytrap.
