Trichomes are one of the micromorphological traits that can be examined to help identify of Asteraceae species. The present study is aimed to describe the diversity of trichomes found in Oligochaeta ramosa (Roxb.) Wagenitz (Asteraceae). Different glandular and non-glandular trichomes were identified, differing in size and shape. It was found that there were several different-shaped multicellular non-glandular and glandular trichomes. After being examined under a light microscope, the trichomes were categorised into 13 categories for this study. The distinguishing feature of Oligochaeta ramosa (Roxb.) Wagenitz consists of glandular and non-glandular trichomes. Non glandular trichomes are simple, multicellular, and long with pointed tips. Besides these, glandular trichomes like sessile and peltate types were also observed in Oligochaeta ramosa (Roxb.) Wagenitz. This study revealed the significance of micromorphological data to assist Asteraceae plant identification
