DESCRIPTION Trilete microspore. Amb triangular with convex sides.Tops are slightly raised. The laesurae are thin, raised, slightly undulating, and bordered by lips in the contact area. Exine cicatricose. On the proximal face, we can observe 3 sets of 4 muri which can fork in each interradial area. Those muri often roll up slightly before joining with the laesurae. The distal face shows muri which form triangles centered on the distal pole; however, those muri are undulating and intersect the bisecting line, alternating from one to another ( Fig. 11 ). Equatorial diameter = 40-60 µm . BOTANICAL AFFINITIES Schizaeales , Anemiaceae .
