Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. Freile 1972 | Grano monocolpado. Contorno de forma elipsoide. Exina de aproximadamente 1 a 1.5 µ de espesor. El colpo se extiende desde 2/3 o más del eje ecuatorial longitudinal, y es aveces algo engrosado. Ornamentación formada por espinas medianas que suelen estar truncadas, lo que le da al grano un aspecto granulado. |
