    Angiosperm Phylogeny, Floral Morphology and Pollination Ecology.A. D. J. Meeuse - 1972 - Acta Biotheoretica 21 (3-4):145-166.
    The different aspects of floral evolution—Angiosperm descent, floral morphology and pollination ecology—are discussed on the basis of the anthocorm theory of the angiospermous flower. Opposed ideas are critically compared and rejected mainly on account of several inconsistencies and flaws in old floral concepts. Floral evolution passed from a very early phase of dicliny, anemophily and aphananthy of the anthocorm to a phase of incipient entomophily soon associated with a partial sex reversal within the anthocorm. This second phase culminated in the (...)

    From Ovule to Ovary: A Contribution to the Phylogeny of the Megasporangium.A. D. J. Meeuse - 1963 - Acta Biotheoretica 16 (3-4):127-182.
    Ausgehend von einer postulierten Abstammung der verschiedenen Gymnospermengruppen und der Angiospermen von Progymnospermen werden die Semophylesen der Samenanlagen und deren „Hüll- und Schutzorganen” eingehend besprochen. Das innere Integument ist phylogenetisch wohl aus verwachsenen sterilen Megasporangien entstanden, das aussere ist das Homologon der Cupula der Samenfarnen und ein Achsengebilde.Die dritte Hülle — die interseminalen Schuppen bei den Bennettiteen, die Chlamys bei den Chlamydospermen, die Fruchtknotenwand bei einigen Angiospermengruppen wie Pandanaceen und Cyperaceen, und der Arillus bei Angiospermen mit karpellaten Gynoezien — ist (...)

    Sixty-Five Years of Theories of the Multiaxial Flower.A. D. J. Meeuse - 1972 - Acta Biotheoretica 21 (3-4):167-202.
    A critical appraisal of the theories founded on the theorem of the multiaxial flower , shows an evolution fromWettstein's original version of 1907 to various hypotheses founded on the the same theme and partly derived from the Wettsteinian doctrine. A number of circumstances such as semantic inconsistencies, but principally the choice of inadequate archetypes, prevented the success of the theory of a polystachyous floral region, because the deductions and interpretations emanating from this concept were not sufficiently convincing to defeat the (...)
