“…Anther wall development type from: Bromeliaceae (Sajo et al, 2005), Typha (Asplund, 1972), Sparganium (Mü ller-Doblies, 1969), Rapateaceae (Tiemann, 1985;Venturelli & Bouman, 1988), Prionium (Munro & Linder, 1997), Cyperaceae (Khanna, 1963;Makde, 1982), Juncaceae (Munro & Linder, 1997), Mayaca (Venturelli & Bouman, 1986), Xyris (Rudall & Sajo, 1999), Eriocaulaceae (Monteiro-Scanavacca & Mazzoni, 1978;Arekal & Ramaswamy, 1980), Abolboda (Tiemann, 1985), Restionaceae (Krupko, 1962), Centrolepidaceae (Hamann, 1975), Flagellaria (Munro & Linder, 1997), Anomochlooideae (this paper), Pharoideae (Sajo et al, 2007), other Poaceae (Bhanwra, 1988;Bhanwra et al, 1991 dyads and tetrads are present together, which is unusual. Among other monocots, such reversals in microsporogenesis type can occur occasionally, for example, most lower asparagoids (Asparagales) are simultaneous, with a reversal to the successive type in Hypoxidaceae and within Iridaceae (Rudall et al, 1997;Penet et al, 2007). The presence of simultaneous microsporogenesis in Streptochaeta does not affect pollen morphology.…”
