Genus Malpighiaceoidites n. gen.
Type species: Malpighiaceoidites periporifer n. gen. et sp.
Diagnosis: Periporate pollen of spheroidal shape; circular to tetragonal or quinquegonal
in outline. Exine four-layered (?), 2 -3.5 pm thick, surface of exine
chagrenate or finely rugulate; with thin and narrow streaks or pseudocolpi. Five to
nine pores with very weak annuli variably distributed, 1. 5- 3 pm in diameter.
Size: 27 - 30 pm in diameter.
Derivation of generic name: After a family of tropical plants (Malpighiaceae) which
got its name from the Italian physiologist and anatomist Marcello Malpighi (1694).
Remarks: The present specimens are very closely similar to the pollen of recent
Malpighiaceae, especially the genus Tristellateia.
Malpighiaceoidites periporifer n. sp.
PI. 20, figs. 7 -14.
Diagnostic description: Periporate (or pantoporate) pollen of circular to subcircular
outline. Exine four-layered (?),
2 -3.5 pm thick, chagrenate to finely rugulate,
with some narrow lineal streaks or pseudocolpi. Five to nine germinal pores variably
distributed, 1.5- 3 pm in diameter and with very weak annuli ( 1 -1. 5 pm wide) .
Measurements: 27 - 30 pm X 25. 5- 30 pm in diameter.
Holotype: PI. 20, figs. 11a-b; 26 X 28 pm in diameter; exine chagrenate, 3 pm thick;
five to six (?) pores 2 - 3 pm in diameter; with lineal streaks or pseudocolpi. No. of
specimen: los 1 - 9 (GN 5329).
Derivation of name: peri (gr.) = around; porifer Oat.) = porus and ferre = having
pores.
Remarks: Many figures of Malpighiaceae pollen (et Perisyncolporites) which came
from the Tertiary of Senegal were published by Medus (1975). These pollen are
very similar to the present los specimens.
Botanical affinity: Malpighiaceae.
