       Abstract: Sino-Vietnamese limestone karsts are biodiversity hotspots in the world and key areas for biodiversity conser ̄
       vationꎬ and many new species of Paraboea have been found there recently. Paraboea minutiflora D. J. Middleton was col ̄
       lected firstly from northern Vietnam in 2001 and was published in 2018ꎬ but it is incomplete and lacks type specimens
       with mature flowers when reported. The description of Paraboea minutiflora was supplemented based on the collections
       from southeastern Yunnanꎬ China and Ha Giangꎬ Vietnamꎬ and line drawing and photos are also provided. Paraboea

       minutiflora is most similar to Paraboea glanduliflora Barnett in having glabrousꎬ reflexed calyx and corolla with glandular
       hairsꎬ but differs from the latter by the upper leaf surfaces covered with brown matted indumentum when youngꎬ but gla ̄
       brescent at maturityꎬ the inflorescences terminalꎬ the corolla 9 - 12 mm longꎬ the capsule straightꎬ 1.2 – 2.8 cm
       long. The discovery of Paraboea minutiflora from southeastern Yunnanꎬ China demonstrates the flora is closely interrelat ̄
       ed between the southern limestone karsts of China and the northern limestone karsts of Vietnam.
       Key words: biodiversity hotspotꎬ limestone floraꎬ Sino ̄Vietnamese limestone karsts
