Conservation
Barleria grandis is localised in distribution but is well represented in herbarium material from western Ethiopia, though this is perhaps in part due to the very showy flowers that are unmissable in the field; the paucity of fruiting collections is notable. It favours areas where human disturbance is likely to be low due to the limited agricultural potential of dry rocky slopes, though overgrazing may be problematic to some populations. B. grandis is currently assessed as of Least Concern (LC) using the IUCN (2001) criteria, though more data on population trends are desirable to confirm this assessment.
Distribution
W Ethiopia and Eritrea; also likely to occur in easternmost Sudan.
Ecology
Recorded from grassland, bushland and woodland of Acacia, Combretum, Terminalia and/or Lannea, being particularly associated with dry rocky slopes in river valleys and gorges; 900 – 1850 m.
Note
With its very large, white or pale pink-flushed corollas, this species is unmistakable. It appears rather isolated taxonomically in Africa, its closest relative perhaps being Barleria grandiflora from India which has a similar corolla. B. grandis displays signficant variation in the relative lengths of the corolla tube and limb, with a particularly long-tubed specimen having been collected from Welaga in westernmost Ethiopia near the Sudan border (Friis et al. 9272). Barleria grandis is the type species of sect. Cavirostrata (Balkwill & Balkwill 1998). However, Ensermu (2006) erroneously treats this species under sect. Somalia, having only seen immature fruits.
