If the stamens project beyond the corolla, they are said to be exserted, and included when shorter than the corolla. When the stamens all turn to one side of the corolla, they are said to be declinate. When a flower has four stamens, two of which are longer than the other two, they are didynamous (Fig. 125). If there are six, with four the longest, then they are tetradynamous. (Fig. 126.) Fig. 125. 121 • The filament is generally, as its name implies, a slender thread-like or- gan, having a bundle of vessels in its center composed of woody fiber and spiral vessels, and corresponds undoubt- edly to the petiole of the leaf. It as- sumes a variety of forms. Its normal form is found in the Rose, Apple, and Lily. In the Canna the filament re- sembles so much a petal that it would Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Darby, John, 1804-1877.
