Abstract: (1) Boehmeria subgen. Duretia sect. Spicatae is recognized, but relegated to serial rank, and treated as one of the series under Sect. Duretia. (2)In Ser. Spicatae are recognized 6 species, including 1 new species, which are keyed, except the new species briefly described, and illustrated. Besides, the geographical distributions and a distribution map of them are provided. (3)The close relationships among the 6 species are discussed, and several speculations are thought out:In Ser. Spicatae, Boehmeria gracilis is the primitive species, and all other species of this series might originate from it; or B.gracilis and B.densiglomerata might be a pair of sister groups derived from a common ancestry; or B.allophylla might be derived from B.silvestrii.
