Two new species of Cyperus (Cyperaceae) from the Zambezian region of Africa

Cyperus absconditicoronatus Banters, Reynders & Goetgh. and C. unispicatus Banters, Reynders & Goetgh., two new species of Cyperus L. (Cyperaceae) from Angola and Zambia, are recognized. Cyperus absconditicoronatus is a tall species (55-100 cm) characterized by a scaled rhizome, a single terminal capitulum, a ciliated spikelet bract, and deciduous spikelets. Cyperus unispicatus can be recognized by a swollen and fibrous stem base growing from slender rhizomes, a single terminal spike, and short involucral bracts. The taxa are described and illustrated, and differences with the closest resembling species are discussed

Answering Key Global IT Management Concerns Through IT Governance and Management Processes: A COBIT 5 View

Drawing on the COBIT 5 framework, this research presents the results of an analysis into which governance and management of IT processes are leveraged in practice for answering two key global IT management concerns: alignment and security. For practice, this research specifically sheds light on which governance and management of IT processes appear to be most important for explaining the achievement of alignment and security. Practitioners can therefore use these results as a benchmark to answer these concerns

Kyllinga cataphyllata (Cyperaceae), a new species from the Highlands of West and Central Africa

Kyllinga cataphyllata, a new species of Cyperaceae from the highlands of Western and Central Africa, is described and illustrated. This new species is easy recognized by the ascending rhizome densely covered by large cataphylls. The head-like inflorescence consisting of a single spike with spikelets made up of two to three glumes and only one flower, and the glumes characterized by a spinulose greenish keel. It is closely related to K. brevifolia, but differs in having conspicuous cataphylls, glumes with a strongly toothed keel and an asymmetrical pedicel to the nutlet
