Morphological diversity of pollen grains within the flowering stages of Tecoma stans (L.) Juss. ex Kunth

“…Within the taxonomical studies, pollen morphology considered as an important tool in plant discrimination and classification to solve many taxonomic problems since [1,21,8]. Despite of the significant role of pollen studies in taxonomical works, there are many errors mentioned by [2] which taxonomists ignored in their conclusions and interpretation and led to wrong decisions. [22] found that pollen morphology is affected by environmental factors as they exposed to dispersing agents in their developmental state which is affected by their water content.…”

“…Despite the importance of pollen morphology in plant taxonomy, many severe faults happened which led to misinterpretations of the data obtained. [2] cited three parameters as the source of these erroneous inferences (1) the interpretations of the palynologist (2) the pollen terminology applied, and (3) the magnification, resolution, and methods used. Many other factors give wrong descriptions, such as the hydration state and the harmomegathic effect resulting from the acetolysis mixture and chemical treatments beside many other environmental factors.…”
