ReferenceDiagnosis
A. E. González-Guzmán 1967Pollen grain triporate, equatorial limb circular; pore P α 1, P β 2, P γ 1; sculpture type reticulate (diameter of lumina about 0.8 μ); thickness of exine about 1.3 μ; ectexine thicker than endexine. Muri simplibaculate and grain semitectate. Sometimes pores of type P α 2, which means that they probably have costar pori, although the latter are not always visible.
