Abstract

A new Anchusa (A. negevensis) (Boraginaceae) from the Negev of Israel is described. It is referred to subgen. Hormuzakia (Guşul.) D. F. Chamb. on account of its helmet shaped nutlets with a hollow base and with a basal dentate ring around the ventral side. Although the only other species in this subgenus (A. aggregata Lehm.) is annual, nutlet morphology is strikingly similar between these two taxa. The new species is a perennial, herbaceous plant with succulent roots and reproduces vegetatively by adventitious shoots from its roots. It is known only from a 0.2 hectare area of weathered, Neogene sandstone outcrop, situated with a sloping aspect and subject to high wind erosion, located 10km SE of Dimona, Israel.
