Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . f a true axillary origin of the organs in question,therefore, appears to be gratuitous, and it would certainly introduce needlesscomplexity into the theory of the flower. Nor does it throw any light upontheir morphology to call such appendages of petals deformed glands ; a termwhich is much too vague to have any assignable morphological value. InLinum true stipules are reduced to glands. At present, therefore, we think thatthe same general name may properly enough be employed both for the collateraland the vertical multiplication of organs, where two or more bodies occupy theplace of one, carefully distinguishing, however, the two different cases. Somespecial term is needful for discriminating between such multiplication and thatby the regular augmentation of floral organs through the development of addi-tional circles, and none the less so, because we recognize, in one or both kindsof chorisis, modes of division which are common to the floral organs and to thefoliage. 248 THE 382 a scale-like appendage; the petals of Sapindus, Cardiospermum,&c, a petaloid scale quite unlike the original petal; the petals ofParnassia, a cluster of bodies resembling sterile filaments unitedbelow. 460. The Antepositioil or superposition of parts which normallyalternate in the flower has in some cases been regarded as a case oftransverse chorisis; but it is susceptible of a simpler principal case that occurs is that of the stamens, or the outer-most circle of stamens, being placed directly before the petals (in ordinary botanical lan-guage opposite the petals).The Vine (Fig. 384-386)and the Buckthorn familiesare good examples of thisanomaly, as also is Clay-tonia in the Purslane fam-ily. And in Linden andmany of its allies a cluster of stamens (Fig. 382, 383) stands be-fore each petal, t
