This study examined the surface features of fruits and seeds of three taxa of the Rosa sericea complex to determine their taxonomic significance and delimitation. The researchers used scanning electron microscopy to observe the surface micro-morphological characters and found 44 different qualities. They also used principal component analysis to analyze the relationship between the studied characters. Density of stomata and trichomes were observed more on the dorsal and ventral parts of the seeds than on the lateral parts. Persistent calyx shape, fruit and seed shape, stomata shape, and trichome size were significant factors in distinguishing between the taxa. This study aims to provide identification keys for the Rosa sericea complex based on fruit and seed morphology.
