Notes on the sweet basil and its wild relatives (Lamiaceae)

Artificial crossing experiments were made with three taxa of Ocimum. Plants ofO. forskolei Benth. andO. basilicum L. var. purpurascens Benth. were found to be interfertile, butO. americanum L. var.pilosum (Willd.) Paton was found to be reproductively isolated from the other two taxa. The new chromosome number 2n = 48 was counted inO. forskolei. These results suggest thatO. forskolei might be the closest relative of the Sweet Basil. The origin of the Sweet Basil is also discussed.
