The published occurrence of Camellia caudata var. caudata in Bhutan (Sealy, Rev. Gen. Camellia, 105. 1958; Ming, Monogr. Gen. Camellia, 202. 2000) is based on T. J. Booth s.n. 1 Nov and 20 Dec at K. However, Thomas Jonas Booth’s collections referring to "Bootan" were made east of Bhutan, in SE Xizang or NE India, in 1850-1851 (Grierson & Long, Fl. Bhutan 1: 8. 1983).
