Notes
Baraajos, saaq-saaq (Som.).Three subspecies were recognized in this variable species by Verdcourt in Kew Bull. 13: 199 (1958), subsp. africana in Africa, subsp. indica Verdc. in India and subsp. plebeia in Malaysia and Australia. However, it is not entirely clear that this taxonomy should be maintained and further studies on the variation pattern of the species are desirable. An older name for the species may be I. biflora (L.) Pers. that was used, for example, by Staples in Flora of China 16: 304 (1995) in a very wide sense, but the identity of Convolvulus biflorus L. is still ambiguous.
