A study was conducted on nine species of Jasminum in Pakistan to examine their pollen types and structures. The study found that these characteristics are conserved in all of the species and are not useful for determining evolutionary relationships. Some species had specific characteristics, such as heteropolarity or foveolate exine ornamentation, but overall, there was little variation. Pollen size differed within species, with Jasminum humile showing the most variation. Some species were unable to develop true pollen due to structural or functional disabilities. The results indicate that quantitative pollen data can be used for grouping Jasminum species but not to infer their evolutionary relationships.
