Clawenia purpurea

The cillaphant grows as a rosette, or cluster, of elongated leaves with sharp edges and pointed tips. From the center of each rosette, two leaves with very different growth form emerge. These are elongated and tubular and able to flex and bend due to the presence of rows of bulliform cells along the length of the leaf. These specialized cells can quickly absorb water and expand to several times their normal size, which causes rapid movement of the leaf. (Read more)
The cillaphant is magnetonastic and able to detect and orient itself towards a magnetic field. When this occurs the tubular leaves will twist to point in the direction of the magnetic field and the sharp tips of the leaves will sometimes eject. (Although this action is believed to be defensive in nature, botanists are still unclear on the exact motive force behind the behavior.) Miners working near deposits of unobtanium are in particular danger from shooting cilliphants; several workers have been hit by the tips without injury.

While the cillaphant typically grows on the soil like other plants, it can survive in a wide range of habitats. It is often found growing attached to other plants, sometimes high in the canopy, where it obtains the water it needs from fog, dew, and rain that collects in the rosette.
