New species and combinations in Acanthaceae from Somalia

摘要

Six species from Somalia, Barleria albomarginata, B. dentata, B. glaucobmcteata, B. ilicifolia, Hypoestes cinerea and Justicia carnosa, are described as new to science, J. arenaria is proposed as a new name for J. ovalifolia var. psammophila and the new combination B. brevispina is proposed for B. linearifolia var. brevispina. During revisional work in various genera of Acanthaceae for the Flora of Somalia project, six previously undescribed species were encountered. They are formally published here,along with a new name and a new combination at species level for taxa previously treated as varieties. The species are arranged in the same sequence as they have in the Flora (Hedren in Thulin 2006).
