f. Rubus exsuccus Steud. ex Richard (1847: 256) .

Lectotype (designated here):—ABYSSINIA [ ETHIOPIA]. ‘In umbrosis lateris borealis montis Aber prope Dsche-nausa’. 28 December 1839, Schimper 867 (lectotype P00374023 [https://science.mnhn.fr/institution/mnhn/collection/p/item/p00374023] ; isolectotypes A 00056042 , BM000622346 , BR 842 202, GH 00056041 (strong sample), K000310009 (the right hand branch), K000310011 , K000310012 , L 0019729 , LG0000090026836 , MPU024530 , P00374017 , P00374018 , S12-13510

Notes: —The specimen P003740122 does not have a printed label. It is similar to the type collected by Schimper and conserved by Steudel. However, the number on the label is different (807). This might be a mistake, but the uncertainty makes it unsuitable for selection as a lectotype.

This species has long patent reddish brown hairs on the stem and in the inflorescence; the serrature is rather obtuse, rounded or triangular, with short mucros; prickles from 1–3 mm broad base are compressed, strongly declining, sometimes somewhat curved, up to 4–5 mm long, stipules 11–15 mm, linear-lanceolate; ovaries glabrous.
