| A taxonomic revision of Arytera Blume is presented, together with a cladistic analysis. On the basis of this analysis, a new genus is recognised, Mischarytera gen. nov., to accommodate the species A. bullata, A. lautereriana, and A. macrobotrys. The necessary new combinations are made. A new classification for Arytera at infrageneric level, also based on the cladistic analysis, is given. Two sections are recognised, Azarytera and Arytera; the latter is further divided into three subsections, Arytera, Distylis subsect. nov., and Pacifica subsect. nov. One new species is described ( A. nekorensis) and one new combination is made ( A. neoebudensis). General, regional, and synoptic keys to all taxa are provided, as are detailed descriptions of the species.... |

| A description of Arytera pollen based on light and scanning electron microscopic observations is presented. Four aperture types and two ornamentation types (one divided into two subtypes) can be distinguished. The commonest aperture types are colporate and parasyncolporate; each of the other two types occurs in a single species. The main ornamentation types are rugulate and striate-rugulate; the latter has small or large lumina. Polymorphism occurs in both characters in several species. A cladistic analysis of Arytera shows two distinct evolutionary trends in the pollen: 1) aperture system from parasyncolporate to colporate, and 2) ornamentation from striate-rugulate with small lumina to striate-rugulate with large lumina. The plesiomorphic state of the... |
