The natural history of plants, their forms, growth, reproduction, and distribution; . ^^muM^^^. Fig. 98.—Plan of Whorled Two-membered Whorl. ^ Three-membered Whorl. fig. 98 ^ is shifted through a quarter of the circumference { through 90°, a rightangle) from the point of origin of the first, oldest, and lowest two-membered third whorl is again shifted through a right angle with regard to the second,and so it continues up the stem as far, generally speaking, as foliage-leaves are tobe found on it. If the stem is elongated in the case described, four rectilineal lines{orthostichies) appear to be developed on it (fig. 98 ^). If a whorl is composed ofthree leaves, and if the successive whorls be displaced through one-sixth of thecircumference, as, for example, in the Oleander (see fig. 98^), six rectilineal series ofleaves or orthostichies originate, running parallel to one another down the stem. The leafy stem can also be imagined as divided into stories, each of whichdisplays the same number, position, and distribution of the leaves, and agreescomple
