Armeria sp.

Figure 3.11

Material. Samples Pb-9340, Pb-8898, Pb-8872, Pb-9137, Pb-9334, and Pb-8896, Palynology Laboratory, IGLUNAM.

Description. Monad, isopolar, radiosymmetric, amb circular, prolate spheroidal. Tricolpate. Exine semitectate, columellate, 5 µm thick, reticulate, supramicroequinate, muri with large columellae of 4.2 µm and lumina 3.6–5.6 µm in diameter.

Dimensions. Equatorial diameter 37–40 µm, polar diameter 35–45 µm, two specimens measured.

Remarks. Armeria is included in Plumbaginaceae . This family is cosmopolitan, although its distribution center is the Mediterranean ( Papanicolaou and Kokkini, 1982).

Comparison. The Armeria pollen type is very similar to the Armeria sp. recovered from the Monterey Formation (Miocene) phosphatic facies, California ( Srivastava, 1984). Both have similar dimensions and ornamentation.

Other occurrences. Mexico – late Eocene to early Oligocene Pie de Vaca Formation, Puebla ( Martínez-Hernández and Ramírez-Arriaga, 1999). U.S.A. – Miocene of the Monterey Formation, California ( Srivastava, 1984).
