A taxonomic synopsis of Heliotropiaceae and new combinations in Heliotropium from Thailand

“… Heliotropium indicum is likely native to tropical America and introduced in all the tropical regions of the world. This species is also a common weed with medicinal properties ( Dash and Abdullah 2013 ). It is most easily recognised by ovate to elliptic leaves with strigose and stiff hairs on both surfaces, truncate or obtuse leaf base, irregularly undulate leaf margins, white to purple or purplish corollas with a yellow-orange throat inside and fruits are deeply 2-lobed with apical divergent lobes.…”
