“…Since comprehensive pollen morphological study on angiosperms, including Impatiens pollen, several palynological studies have been carried out that focused on the pollen morphology of Impatiens (Narayana & Sayeeduddin, 1959;Huynh, 1966Huynh, , 1968Bhaskar & Razi 1973, 1979Tara & Namboodri, 1974;Bhaskar & al., 1975;Moore & Webb, 1978;Grey-Wilson, 1980b;Lu, 1991;Perveen & Qaiser, 2001;Janssens & al., 2005Janssens & al., , 2009aJanssens & al., , 2011Vinckier & al., 2012). Despite these studies, the pollen morphology of Impatiens is still underexamined due to the large size of the genus.…”
