3. Senegalia caesia (L.) Maslin, Seigler & Ebinger, comb. nov.

Mimosa caesia L., Sp. Pl. ed.1, 1 (1753) 522. — Acacia caesia ( L.) Willd. (1806) 1090. — Lectotype: Herb. Herman 2: 50, No. 217, BM (Rico in Turland & Jarvis 1997: 475).

Distribution — India, Sri Lanka, Bhutan, Bangladesh, Myanmar ( Burma), central and southern China (Guangdong, Hainan, Sichuan & Yunnan Provinces), Thailand, Laos, Cambodia, Vietnam, Taiwan.

Notes — Although A. caesia var. subnuda is recognized by Roskov et al. (2005), based on the works of Nielsen (1981: 53) and Sanjappa (1992: 37), it is regarded as conspecific with A. caesia by Chakrabarty & Gangopadhyay (1996: 604) and Wu De-Lin & Nielsen (2010: 57). We have therefore followed the most recent taxonomy in not recognizing the variety here . However, it should be noted that Nielsen should have adopted the name var. oxyphylla for this taxon; therefore, if this entity is ever recognized as a variety, either in Acacia or Senegalia , then the combination based on A. oxyphylla will need to be made. Although Roskov et al. (2005) list A. caesia as occurring in Java and the Philippines it is doubtfully native there because it is not listed for these regions by Nielsen (1992) or Wu De-Lin & Nielsen (2010).
