Focus on this artwork and explain the Description.
The sculpture depicts an oversized leaf of the American tulip tree, Indiana's state tree. The sculpture consists of two main segments: the leaf, which forms the main body and majority of the piece, and the petiole-and-bowl segment, which houses the drinking fountain. Measured diagonally from the foremost tips of the leaf segment to the back of the fountain bowl, it is about 207 inches (530 cm) long.  
The leaf segment is approximately 172 inches (440 cm) at the widest point and rises about 16 inches (41 cm) off the ground at its highest point. It is made from sections of sheeted stainless steel, overlapped and bolted together using brass bolts and acorn nuts, supported by rib-like structures on the underside, and curled to mimic the organic shape of a leaf. It is completed by a long piece of stainless steel which forms the midrib of the leaf. The entire leaf segment is held slightly off the ground on support bars of varying length. A series of small electric lights is arranged under it in order to produce a glow from underneath at night.
The petiole-and-bowl segment stands independently of the leaf section, but is positioned to give the impression that the midrib continues into the petiole. It rises approximately 42 inches (110 cm) off the ground, not including the water spigot. The stainless steel petiole structure stands atop a small stone base and supports the main bowl structure, which is made of copper. A thick, slightly irregular, oblong ring of limestone forms the lip of the drinking fountain basin. The spigot itself is an ordinary manufactured fixture; it is attached to the central copper portion of the bowl.
