The plant specimens have been collected from the forests of Chittagong, Hill Tracts districts, Cox’s Bazar and Sylhet through field trips under Aberdeen University-Chittagong University (AU-CU) Biodiversity Link Project and kept in the Herbarium of Chittagong University (HCU). The specimens of the Rubiaceae available at (DACB), CAL, Salar Khan Herbarium of Dhaka University, Bangladesh Forest Research Institute herbarium (BFRIH) and Bangladesh Council of Scientific and Industrial Research herbarium, Chittagong (BCSIRH) were also studied. The specimens were studied at HCU using Long Arm Stereo Microscope and identified by consulting relevant literatures (Hook. f. 1880, Prain 1903, Brandis 1906, Kanjilal et al. 1939, Deb 1983, Dutta and Deb 2004). The identifications were confirmed by matching with the named specimens and as well as by consulting experts of ABD, BM, CAL, E, K and L. The photographs of fertile specimens have been taken either from the field or from the herbarium specimens by using digital camera. Illustrations of some of the new records has also been done at the herbarium. The herbarium specimens are available at DACB, BFRIH, BCSIRH and HCU.
