|---|---|---|
| S. Archangelsky 1973 | Grano prolado a subprolado. Colpos llegando cerca de los polos, con visible engrosamiento o margo, más desarrollado en el sector ecuatorial. Poros aparentemente algo lalongados, de contornos poco nítidos. Exina compuesta por dos capas, tectada. Capa interna del mismo espesor o algo más delgada que la externa. Columelas uniformemente distribuidas, formando en general un microretículo con mallas de 0,5 µ, o menos, de diámetro. Tectum liso. Exina normalmente de grosor parejo, a veces levemente más gruesa en los polos, donde las columelas son algo más largas. | |
| L. R. Mautino and L. M. Anzótegui 2002 | Pollen grain prolate to sub-spheroidal. Colpi almost reaching the poles with ridges more developed in the equatorial region. Ora lalongate (2-5μm X 3.5-7.5 μm), sometimes obscured. Exine tectate formed by two layers. Nexine of the same thickness or thiner than sexine. Columellae forming an homogeneous microreticulum with lumina of approximately 0.5 μm or less in diameter. Smooth tectum. Exine of uniform thickness (1-1.5 μm) or slightly thicker at poles, where the columellae are slightly higher. |
