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.

Two New Species of Cyperus (Cyperaceae) from the Zambezian Region of Africa

Abstract Cyperus absconditicoronatus Bauters, Reynders & Goetgh. and C. unispicatus Bauters, 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.
