- Diagnosis
- Monosulcate, roughly bilateral, reticulate pollen with short, dense auriculae at ends of the sulcus. Sulcus as irregular compressed fold or as elongate open area with expanded ends that reach the equator of the grain. The auricula wraps around the end of the sulcus as a curved band or U-shaped pad usually convex to the proximal pole. An endexine or foot layer is present but very thin except at the auriculae. The auriculae appear to be constructed
of an expanded dense foot layer overlain by a thinned, psilate to punctate tegillum. The auriculae are thus an integral part but easily differentiable from the rest of the exine. A reticulum is developed over the surface of the grain, but not including the auriculae. Muri are generally smooth and taper from
a broad, but apparently non-columellate base. Lumina are of irregular shape and distribution ; occasional specimens exhibit tendency to have coarsest lumina away from the sulcus or at the proximal pole (opposite the sulcus).
