Volatile oil composition in the leaves (a), comparison of the variable sites in the matK sequence (b), comparison of the variable sites in the 18S rRNA sequence (c) and cluster trees of both the matK and 18S rRNA gene sequences (d) of Pogostemon cablin (Blanco) Benth. from 6 different locations. The top number indicates the nucleotide position upstream of the matK (b) and the 18S rRNA (c) sequence, an asterisk (*) indicates the same nucleotide as the P1 sequence, and a hyphen (—) indicates an alignment gap (c)
