Sir The characters 'number of pinnae and number of leaflet' are overlapping. Therefore, it is sometimes difficult to identify based on herbarium specimens. Place of collection will give basic idea whether the species is S. catechu or S. chundra. Senegalia polyacantha is distributed almost every state of India except northeast and temperate regions. To confirm the identity, it is important to observe bark, young stem, calyx. Pods of S. catechu and S. chundra are similar. They are reddish brown to brown at maturity while S. polyacantha showed light brown pods. Please check the photographs which are attached in these mails. Also, please observe prickles are brown, smaller, about 2-4 mm in S. catechu and S. chundra while prickles are light brown, husk coloured and longer, about 3-8 mm in S. polyacantha.
