A general introduction to Zingiber is provided, along with an outline of the materials and methods used in this paper and which are to be used in our subsequent taxonomic studies on Zingiber in China. Based on an investigation of the protologues, and on comparisons of both the type specimens and living materials collected from the type localities and their immediate vicinities. Zingiber stipitatum S.Q.Tong and Z. menghaiense S.Q.Tong are here reduced to synonymy under Z. kerrii Craib. A previous lectotypification of Zingiber kerrii is discussed and amended. The existence of mixed collections among the isotypes of Zingiber stipitatum is highlighted and a proposal to exclude the vegetative parts belonging to Z. neotruncatum from the type material is made. A description and a colour plate of Zingiber kerrii based on a collection from China are provided.

The present work represents the first comprehensive taxonomic revision of Acacia sens. lat. (Leguminosae: Mimosoideae) in China, focusing on the indigenous species. Critical reassessments of specimens and re-definition of previously recorded species have resulted in recognising 21 indigenous species under Senegalia, a segregate of the former Acacia sens. lat. Detailed botanical profiles are provided for these species, together with a diagnostic line drawing and distribution map; photographs of living plants are provided for more than half the species. Terser treatments are also provided for the 15 species from four genera that are regarded as major introductions of Acacia sens. lat. to the country: Acacia Mill. (12 spp.), Acaciella Britton & Rose (1 sp.), Senegalia Raf. (1 sp.) and Vachellia Wight & Arn. (1 sp.). An identification key to all Acacia sens. lat. species in China is provided.The indigenous species of Senegalia in China belong to sect. Monacanthea (Vassal) Maslin, comb. nov., and the introduced ones to sect. Senegalia.As a consequence of this study, the number of Senegalia species now recognised for China has almost doubled. Six new species are described: Senegalia clandestina Maslin, B.C.Ho, H.Sun & L.Bai, sp. nov.; Senegalia guangdongensis Maslin, B.C.Ho, H.Sun & L.Bai, sp. nov.; Senegalia obliqua Maslin, B.C.Ho, H.Sun & L.Bai, sp. nov.; Senegalia orientalis Maslin, B.C.Ho, H.Sun & L.Bai, sp. nov.; Senegalia prominens Maslin, B.C.Ho, H.Sun & L.Bai, sp. nov.; Senegalia stipitata Maslin, B.C.Ho, H.Sun & L.Bai, sp. nov. Four new combinations are established: Senegalia garrettii (I.C.Nielsen) Maslin, B.C.Ho, H.Sun & L.Bai, comb. & stat. nov.; Senegalia kerrii (I.C.Nielsen) Maslin, B.C.Ho, H.Sun & L.Bai, comb. & stat. nov.; Senegalia kunmingensis (C.Chen & H.Sun) Maslin, B.C.Ho, H.Sun & L.Bai, comb. & stat. nov.; Senegalia macrocephala (Lace) Maslin, B.C.Ho, H.Sun & L.Bai, comb. nov. Senegalia andamanica (I.C.Nielsen) Maslin, Seigler & Ebinger and S. macrocephala are new records for China.A lectotype is designated for Acacia teniana Harms and 2nd step lectotypifications effected for Acacia delavayi Franch., Acacia insuavis Lace, Acacia pruinescens Kurz and Acacia yunnanensis Franch. Former holotype citations are corrected to lectotype for Acacia hainanensis Hayata, Acacia macrocephala Lace, Acacia oxyphylla Graham ex Benth. and Acacia philippinarum Benth. A neotype is designated for Acacia arrophula D.Don.China is a principal area of species-richness for Senegalia in Asia. Senegalia displays a high degree of endemism within China and almost half the species are endemic or near-endemic, with Yunnan the most species-rich and species-diverse Province.

Abstract-The relationship between language and culture make culture teaching enter into FLE that cultural understanding of the target language is indispensable. But much emphasis on western culture led to Chinese culture aphasia among Chinese English learners. Consequently, an investigation is conducted in this paper to check whether the phenomenon exists; and if so, to test the extent, reasons and feasible solutions of students' aphasia of Chinese culture. The results demonstrate the tested college students master the Chinese culture well, but have difficulties in translating them into English and some college English teachers are not proficient in translating sentences containing Chinese culture into English. Chinese Culture Aphasia is due mainly to lacking of Chinese culture in college English teaching class. Based on analyzing results of the investigation and summarizing scholars' teaching strategies, the author claims the incorporation of Chinese culture into college English teaching adhering to certain principles, effective teaching strategies including preparing reasonable syllabus and improving teachers' comprehensive qualities.
