Two new species of Vigna (Leguminosae) from Somalia

The new species Vigna monantha ( V. subgen. Vigna sect. Catjang ) from coastal dunes of northern and central Somalia, and V. virescens ( V. subgen. Macrorhynchus ) from the inland of central and southern Somalia are described and illustrated. V. virescens is unique in Vigna by having branched stylar hairs, a character indicating a relationship between V. subgen. Macrorhynchus and the monotypic Wajira.     

Two new species of Ormocarpum (Leguminosae) from Somalia

Ormocarpum gillettii and O. rectangulare from respectively central and southern Somalia are described and illustrated.     

Two new species of Crotalaria (Leguminosae) from Somalia

The new, closely related species Crotalaria mudugensis and C. camptosepala , with vicarious distributions in central Somalia, are described and illustrated. The two species are regarded as members of C. sect. Crotalaria along with the related C. verdcourtii and C. deflersu that have previously been placed in sect. Hedriocarpae.     

A new species of Microcharis (Leguminosae) from Somalia

The new species Microcharis omissa , from the sandstone escarpment near Yasoomman in central Somalia, is described. This apparently narrow endemic is closely related to M. sessilis in north-eastem Somalia.     

Acacia ochracea (Leguminosae-Mimosoideae), a new species from Somalia

Acacia ochracea , a new species in the A. Senegal complex, is described and illustrated. It is a common and conspicuous tree over large areas in the western Bay Region and in the Gedo Region in SW Somalia.     

Acacia sousae (Leguminosae: Mimosoideae) a new species from Mexico

A new species,Acacia sousae, from the states of Guerrero and Puebla is described and illustrated. A key for determination of the related species is given.     

Two new species of Jatropha (Euphorbiaceae) from Somalia

The new species Jatropha miskatensis , from limestone slopes of the Cal Miskaat Range in north-eastern Somalia, and J. marmorata , from bushland on shallow soil over limestone just south of the Nugaal valley in north-eastern Somalia, are described. An illustration is provided for J. miskatensis.     

Two new species of Dyschoriste (Acanthaceae) from Somalia

The new species Dyschoriste bayensis, from a granitic inselberg in southern Somalia, and D. miskatensis, from open bushland on limestone in north-eastern Somalia, are described and illustrated.     

Two new species of Polygala (Polygalaceae) from Somalia

The new species Polygala praetermissa , a dwarf perennial herb growing in stony places on limestone, and P. dasanensis , a shrublet apparently confined to gypsum, are described. Both species occur in the Cal Miskaat Range in north-eastern Somalia, but P. praetermissa has a wider distribution in northern Somalia.     

Two new species of Monadenium (Euphorbiaceae) from Somalia

Two species of Monadenium, M. gillettii related to M. ellenbeckii , and M. lindenii related to M. virgatum are described as new endemics of Somalia.     

Two new species of Abrus (Leguminosae-Papilionoideae) from Somalia

The new species Abrus baladensis , from fixed sand dunes near Mogadishu in south-central Somalia, and A. gawenensis , from limestone or sand over limestone in central Somalia, are described.     

A new species of Acacia (Leguminosae) from the Horn of Africa

Acacia cernua , sp. nov., is described from open Acacia-Commiphora bushland on the foothills of the north-facing limestone escarpment running along the coast of northern Somalia. The new species is obviously closely related to the widespread A. etbaica that is common on this escarpment, but at considerably higher altitudes. A. cernua differs from A. etbaica in, for example, its smooth, ash grey to white bark, and in its slender, hanging terminal branches with a glaucous foliage.     

Two new species of Acacia (Leguminosae-Mimosoideae) from Yemen

The new species Acacia harala and A. mahrana , both from southern Yemen, are described and illustrated. A. harala belongs to A. subgen. Acacia and is known from the Abyan and Shabwah Regions, whereas A. mahrana belongs to A. subgen. Aculeiferum and is known only from the Mahrah Region.     

Two new species of Dicoma (Asteraceae) from Somalia and Ethiopia

Two new species of the genus Dicoma, D. popeana from Somalia and D. aethiopica from Ethiopia, both of the section Psilocoma , are described and illustrated. The two species are distinguished from D. anomala and other similar taxa by a morphologic diagnostic key.     

Two new species of the genus Dicoma (Asteraceae) from Somalia

Two new species, Dicoma gillettii and Dicoma scoparia (Asteraceae), both from Somalia, are described and illustrated. The differences between the new species and related taxa are listed.     

Two new Neogaillonia species (Rubiaceae, tribe Paederieae) from Somalia

Two new species of Neogaillonia, N. somaliensis and N. calcicola , both endemic to NE Somalia, are described. Palynological data are given for both species. Relationships to other taxa of Neogaillonia and the "Gaillonia complex" are discussed.     

A new species of Croton (Euphorbiaceae) from Somalia

Croton crispatus , sp. nov., from Acacia-Commiphora bushland on sand in central Somalia, is described and illustrated.
