Orobanche tetuanensis Ball (Orobanchaceae) resurrected

Abstract

Orobanche tetuanensis Ball (Orobanchaceae), a problematic taxon initially described from specimens found in the Beni Hosmar Mountains (Tetuan, Morocco), was identified in this work from the original material collected by Ball [K 96690!]. This taxon features: upper leaves and bracts highly densely covered with up to 1.5-mm-long glandular, woolly, rusty-coloured hairs; a campanulate corolla, (14-)16-20 mm in size, that is reddish-brown on the outside and dull red on the inside, is covered with 0.5-1.2-mm-long hairs (mainly in the upper half), and has lip margins with short (0.1-0.2 mm) glandular hairs, in addition to slightly prominent lips and throat of a dull red colour when dry; and narrow staminal filaments inserted very near the base that are glabrous at the base and possess sparse short glandular hairs at the apex. The plant grows in the western Mediterranean region and can be considered as an endemic of north-west Morocco. © 2007 The Linnean Society of London.
