“…is restricted to the Guianas and the Brazilian Amazonian States Amapá and Pará (Maas & Westra 1985). e species was studied in the Nouragues Natural Reserve (4°5´N, 52°41´W) in French Guiana in an almost pristine tropical lowland forest (Teichert et al 2011). e two South American species, A. manausensis Timmermann and A. brevipes Benth., as well as the South American/Central American A. phaeocarpa Martius were all studied in Central Amazonia in Brazil, in the surroundings of Manaus, either in the natural forest reserves of the Reserva Ducke or the Campus of the Universidade de Manaus (Webber & Gottsberger 1994;Webber 1996;Jürgens et al 2000), e South American/ Central American A. crassipetala Hemsley was studied in forests at the Organization for Tropical Studies eld station at La Selva, Costa Rica (Armstrong & Marsh 1997;Collier & Armstrong 2009), Finally, the widely distributed South American/Central American species A. dolichocarpa Sprague & Sandw.…”

“…ere is, however, quite a variation of anthesis rhythms among di erent individuals of a species. For example, in A. prinoides, the rare phenomenon of heterodichogamy is acting (Teichert et al 2011). Within the population of A. prinoides, two morphs having di erent owering chronologies occurred (Fig.…”

“…Pollinators leaving such an isolated ower will transfer pollen to the ower of another individual (Webber 1996;Teichert et al 2011;Braun & Gottsberger 2011). In A. brevipes there is another mechanism for inducing a high probability of cross-pollination.…”

Data of six studied Neotropical Anaxagorea species are analyzed and discussed with respect to the population structure, owering phenology, ower morphology, anthesis, scent emission, thermogenesis, oral visitors, breeding system, fruit-set and seed dispersal. e probably reason for the patchy distribution of small populations of Anaxagorea species within lowland tropical forests is given. A novel explanation of the functional signi cance of ruminate endosperm is presented. Flowering of the species follows either the annual or the continuous owering pattern. All studied species have diurnal, two-day lasting, protogynous anthesis; several species have thermogenic owers. Self-compatibility appears to be the prevailing reproductive system in the genus. However, there is a strong tendency for e ecting cross-pollination. Floral scent of Anaxagorea species contains fruit-like components, and the pollinators, primarily Nitidulidae (Colopterus spp.) are attracted by deceit. Strong scenting pollination chambers occur also in most other cantharophilous Annonaceae. Novel oral developments are apparent mainly in y-, cockroach-and bee-pollinated Annonaceae, which have patterns di erent from cantharophilous species and exhibit open owers with re exed petals, which allow their pollinators to reach and touch the reproductive organs.
