TAXONOMIC NOTES

Morphologically, Scutellaria repens is similar with S. scandens by having scandent stems and axillary racemes ( Paton 1990), but the two species are differentiated by nutlets, stems and flowers. Scutellaria repens has grey-black, subpapillate, pubescent nutlets, wingless stems, and a parallel-sided corolla tube, while S. scandens has brown, papillate, glabrous nutlets, obviously winged stems, and a bent and saccate corolla tube base. Paton et al. (2016) indicated that S. shweliensis W. W. Sm. and S. tenasserimensis A. J. Paton are closely related to S. repens rather than S. scandens . Morphologically, all the former three species have subpapillate, pubescent nutlets and parallel-sided corolla, but can be distinguished by other characters.
