The undigested part forms a central binder holding the four microspores of the tetrad together. This process causes the microspores to rotate 180 degrees. In this paper we describe pollen formation in another annonaceous genus, Cymbopetalum, in which the pollen is shed in octads, through use of light microscopy, epifluorescence microscopy, and TEM. In Cymbopetalum, two meiocytes, connected by abundant cytomictic channels, are produced in each sporangium. Octad pollen formation in Cymbopetalum is shown to be comparable to the synchronized formation of two connected Annona tetrads, which then integrate into a single octad. Unique features of Annona polyad formation, e.g. special binding between the callose-cellulose envelopes and microspores, incomplete callose digestion, and microspore rotation, also occur in Cymbopetalum. In addition, formation of the Cymbopetalum octad involves development of a cushion-like structure that binds the distal pronexine of all eight microspores, and there is the production of intine protrusions. The evolutionary origin of the callose-cellulose binding mechanism within the family is discussed.}, keywords = {angiosperms, Annona, Annonaceae, ASIMINA-TRILOBA ANNONACEAE, CALLOSE DISSOLUTION, callosic envelope, compound pollen, Cymbopetalum, DEVELOPMENTAL, EVENTS, EVOLUTION, GENERA, microspore rotation, octad pollen, SPORODERM DEVELOPMENT, TAPETUM, TETRADS}, isbn = {0378-2697}, author = {Tsou, C.

These species were placed by Fries in Guatteria sect. Mecocarpus (Fries 1939) (the name derives from Ancient Greek \&$\#$956;\&$\#$951;\&$\#$954;\&$\#$969;\&$\#$957; = Poppy and \&$\#$954;\&$\#$945;\&$\#$961;\&$\#$960;\&$\#$959;\&$\#$962; = fruit: fruit resembling that of Papaver species). All occur in South America, none having been found elsewhere so far. Although there is much doubt nowadays about the taxonomic significance of Fries{\textquoteright}s sections, we maintain sect. Mecocarpus at present for convenience{\textquoteright}s sake. Additionally, the former genus Guatteriopsis, united with Guatteria a short time ago (Erkens \&$\#$38; Maas 2008b), is now also included in sect. Mecocarpus. The same applies to one of the two species attributed to Guatteriella (also merged with Guatteria by Erkens \&$\#$38; Maas 2008b), namely Guatteriella tomentosa R.E.Fr. (not Guatteria tomentosa Rusby) which is put into synonymy with Guatteria trichocarpa Erkens \&$\#$38; Maas. One new species is described, namely Guatteria griseifolia Maas \&$\#$38; Westra. The two species complexes of G. guianensis and G. decurrens are now treated each as a single polymorphic species.

This relationship was also supported by endosperm rumination patterns in the seed; other morphological characters furthermore indicated that D. saccopetaloides has closer affinities with Monoon, Neo-uvaria, and Phaeanthus rather than either Sageraea or Stelechocarpus. Desmos saccopetaloides is distinguished from these genera by its leaf-opposed inflorescences, sepaloid outer petals, saccate inner petals with basal glandular tissue, moniliform monocarps with uniseriate seeds, and rectangular disulculate pollen with two {\textquotedblleft}cryptoapertures{\textquotedblright}. On the basis of the combined molecular phylogenetic and morphological data, we propose a new genus, Wangia, to accommodate D. saccopetaloides.
