|How To Climb This Tree
of all, a phylogenetic tree represents how a particular species evolved.
At each node (intersection) of the tree, a specific characteristic
separates the organisms. These characteristics are written in
yellow. Each of the boxes represents
a particular order of angiosperms, which is written in
pink. Lastly, the genus of a species
in written in blue. The closer the
genus is located to another, the closer they are related. The genus
Dionaea is located in the second box.
Where Does The Venus Fly Trap Come
Dionaea muscipula is placed in the order Caryophyllales.
Other members in this order include: Nepenthes, Drosophyllum,
Habropetalum, Dioncophyllum, Triphyophyllum, Drosera, and Aldrovandra.
They are all members of this order because they exhibit
(For more details about
classification, see the Home page). By
looking at the tree, Drosera, Dionaea, and Aldrovandra are the close
relatives to each other because of their characteristic trapping mechanism. Dionaea and Aldrovandra have the most advanced traps,
therefore, they are the closest in relation of all other carnivorous plants. (Check
out the Adapt to Trap page to see how
this mechanism functions).
