摘要: (1)接受荨麻科苎麻属大叶苎麻亚属小赤车组,但将其降为系级群,作为大叶苎麻组的一个系处理。(2)在小赤麻系中共承认6种,其中包括1新种,给出了6种的检索表,简要形态描述(对新种给出完整描述)和插图,还提供了6种的地理分布和分布地图。(3)讨论了6种的密切亲缘关系,并提出几个推测:小赤麻系中的原始种是细野麻,此系其他种可能均自其演化而出;也可能细野麻和密球苎麻为自同一祖先演化而出的一对姊妹群;也可能异叶苎麻自赤麻演化而出。

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.
