TL;DR: The pollen morphology is distinguished from both Ecbolium Kurz and Megalochlamys Lindau by several important features and this supports placing this species in a new genus, Trichaulax, which is previously undescribed in the family Acanthaceae.
Abstract: The pollen morphology of Trichaulax mwasumbii Vollesen is described and illustrated. The pollen is highly distinctive and of a type previously undescribed in the family Acanthaceae. It is subprolate to prolate, (4-)5(-6)-colporate, with complex and rather variable ornamentation, consisting of areas of semitectate, coarse rugulate exine in the centres of the mesocolpia, surrounded by alternating fine and coarse rugulate bands. Occasional grains with abnormal ornamentation were observed. The ectexine consists of fairly short, well spaced columellae, with a granular foot layer. Pollen was stained, according to availability, using the method of Alexander, to test for potential fertility. The pollen morphology is compared with that of Ecbolium Kurz and Megalochlamys Lindau, the nearest known relatives. It is distinguished from both of these by several important features and this supports placing this species in a new genus, Trichaulax.
