    • n stem The body of a tree, shrub, or plant; the firm part which supports the branches; the stock; the stalk; technically, the ascending axis, which ordinarily grows in an opposite direction to the root or descending axis. The stem is composed of fibrous, spiral, and cellular tissues, arranged in various ways; it typically assumes a cylindrical form and a perpendicular position, and bears upon it the remaining aèrial parts of the plant. Its form and direction, however, are subject to much variation in particular cases. In regard to internal structure, there are three principal modifications of stems characteristic of three of the great natural classes into which the vegetable kingdom is divided—namely, exogens, endogens, and acrogens. Stems are herbaceous or woody, solid or hollow, jointed or unjointed, branched or simple. Sometimes they are so weak as to be procumbent, although more generally firm and erect; sometimes weak stems are upheld by twining or by other methods of climbing. In some plants the stem is so short as to seem to be wanting, the leaves and flower-stalks appearing to spring from the top of the root. There are also stems, such as the rhizome and tuber, which, being subterranean, have been mistaken for roots. See cuts under baobab, esparto, internode, pipsissewa, snakeroot, rhizome, and tuber.
    • n stem The stalk which supports the flower or the fruit of a plant; the peduncle of the fructification, or the pedicel of a flower; the petiole or leaf-stem. See cuts under pedicel, peduncle, and petiole.

    • n stem In ornithology, the whole shaft of a feather.
    • n stem In entomology, the base of a clavate antenna, including all the joints except the enlarged outer ones: used especially in descriptions of the Lepidoptera.
    • n stem In musical notation, a vertical line added to the head of certain kinds of notes. Of the kinds of note now in use, all but two, the breve and the semibreve, have stems. It may be directed either upward or downward, thus, . When two voice-parts are written on the same staff, the stems of the notes belonging to the upper part are often directed upward, and those of the lower part downward, particularly when the parts cross, or both use the same note (see figure). The latter note is said to have a double stem. See note, 13. Also called tail.
