In many cases they fall off very early, especially that serve for bud-scales, as in Magnolia. 153. The Arrangement of Leaves on the stem ha.'i already been ex[)lMined as to the two principal ways (59). Leaves are either AUerntdc, when they follow each other one by one, as in the Morning-Glory (Fig. 4) and the Linden (Fig. ?>T,)- or Oj>posite, when in pairs, that is, two on each joint of steni, one opposite the other, as in Maples (Fig. 8^). To these may be added a third, but less common arrangement, viz., the Whot'Icil; where there are three, four, or more leaves on the same joint of stem, forming a circle or w7<or/; as in Madder and Bedstraw (Fig. 13/). variety of the opposite 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 Gray, Asa, 1810-1888; Lawson, George, 1827-1895.
