- Diagnosis
- Miospores free, trilete, radiosymmetrical, anisopolar; amb circular to elliptical or sub-triangular, sides convex, distal side convex, proximal side pyramidal with sunken interradial areas; laesurae distinct, rarely inconspicuous, long, straight, reaching equator, raised, labiate; margo about 1.5-3.5 um wide where well-developed, occasionally bifurcating at ends of laesurae; two-layered exine, including sculptural processes, 5.0-8.5 um wide thinning to usually less than 5 um on proximal side; proximal side usually undulate, invaded marginally by distal sculpture, with well-developed regular reticulum, muri thick, 2.0-4.5 um, lumina elliptical in distorted specimens, circular in others, 2.5-5.5 um wide; distal side sculptured with long echinate, spinulose, blunt, or truncated processes, rarely sharp or bifurcate, either curved Or straight-sided, occasionally with a bulbous base, 3-6 um long, 2.0-4.5 um wide at base, base circular and broad coalescing to form a coarse reticulation with varying degrees of development, exine rarely scabrate on and/or between processes, variations in types of sculptural processes occur on the same specimens.
