| Abstract | The pollen morphology of Thai Acanthaceae Subfamily Nelsonioideae was investigated. The pollen type was tricolpate. Their apertures were longitudinal narrow colpi with acute ends. The polar axis length (P) was 16.3?42.5 ?m and equatorial axis length (E) was 17.5?37.5 ?m. The largest size was represented in Staurogyne dispar, while the smallest showed in Nelsonia canescens, Staurogyne glauca, and S. parvicaulis. The shape varied from suboblate to prolate. Micro-foveolate, foveolate, and rugulate tecta were found in 6, 11, and 7 taxa of Nelsonia and Staurogyne, respectively. Psilate was only revealed in Staurogyne macrobotrya. The wall thickness varied from 1.25?2.5 ?m depending on species. |
