Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. M. Baldoni 1992 | Trilete spore with triangular to subtriangular amb in polar view. Laesurae straight to slightly sinuous, length 3/4 radius of spore or less, with slightly developed
lips 2-3 um wide. Exine rugulate-verrucate on both proximal and distal faces. Sculptural elements are less developed on the distal face and tend to join together on the proximal face.Verrucae with flat or gently rounded apices, up to 5 um high and 2 urn wide, bases free or fused. Rugulae generally continuous at the equator forming striae or parallel ridges, 0.5-1.5 um apart. In the contact zone these rugulae are frequently concentrated, causing a microreticulate sculpture with lumina about 1.5 um diameter and muri 3-4 um wide. Exine 2-2.5 um thick. |
