However, A. hookeri can be distinguished by its sparsely hairy adaxial and white tomentose abaxial leaf surfaces, 6–15-flowered, dichotomously branched cymes, lance-ovate caducous bracts and outwardly reflexed lance-ovate sepals with acute apex. In addition, both the species shows a disjunct distribution. Some additional morphological differences between these taxa are given in Table 1 and Figure 1.</p><p>Based on extensive field surveys along the Western Ghats and after examining the herbarium specimens of Argyreia at AHMA, BLAT, BSI, CALI, DRC, MH and TBGT, it is concluded that A. hookeri does not occur in the Western Ghats. After careful scrutiny of our own collections and specimens at above mentioned herbaria, it is revealed that whatever specimens collected and identified as A. hookeri from the Western Ghats are actually belong to A. boseana . The original taxon identified erroneously as A. hookeri by Cooke (1908) was later described as A. boseana by Santapau and Patel (1958). The Cooke’s concept of A. hookeri was, however, followed by succeeding taxonomists (Sharma et al., 1984; Venkanna &amp; Das Das, 2001; Ramaswamy et al., 2001; Manikandan &amp; Lakshminarasimhan, 2013; Nayar et al., 2014). Report on the occurrence of A. hookeri in Western Ghats is thus erroneous.</p></div>	https://treatment.plazi.org/id/038587FFFF9FFF982B5CFC37FD82F987	Public Domain	No known copyright restrictions apply.
