Description of a new species of Nitrosococcus

A new species of Nitrosococcus is described. It resembles Nitrosococcus oceanus in shape, size, and ultrastructure of the cells. However, the new species has a more pronounced salt requirement, corresponding to its natural habitats. Two strains were isolated from a salt lake in Saudi Arabia and a salt lagoon in the Mediterranean Sea, respectively. In contrast to N. oceanus, both isolates of the new species were unable to utilize urea as ammonia source. Both species also differed in gelelectrophoretic cell protein patterns. The name N. halophilus is proposed.

Three new species of Acanthaceae from Ethiopia

Summary  Three new species of Acanthaceae, Lepidagathis pseudoaristata Ensermu, Acanthopale aethio-germanica Ensermu, and Rhinacanthus mucronatus Ensermu, are described from Ethiopia. The three species are illustrated and their distributions mapped. The three new species are also compared to their presumed closest relatives. L. pseudoaristata is restricted to the Bale and Sidamo Regions, A. aethio-germanica is more widely distributed in Ethiopia occurring in the Kefa, Arsi, Sidamo and Bale Regions, and R. mucronatus is a local endemic restricted to the Borana area in the Sidamo Region. The conservation status of each species is also assessed.

An integrative approach to species delimitation in Echinodorus (Alismataceae) and the description of two new species

Summary  Taxonomy of the genus Echinodorus is partially revisited in the light of current understanding of the phylogenetic relationships of the genus. As a result of new taxonomy, the species status of some previously synonymised taxa are restored, other names are synonymised, and some nomenclatural problems unnoticed by previous authors are resolved. Two new species, Echinodorus reptilis and E. emersus are described. The subgeneric divisions of the genus are not accepted, and all subspecific taxa are either rejected or established as species. As a result, 28 species based on a phylogenetic species concept are now recognised in Echinodorus and an identification key to these species is provided.     

Two new species ofHeleococcum withAcremonium anamorphs

Two new species ofHeleococcum (a cleistothecial nectrioid genus in the Hypocreaceae) are described and illustrated.Heleococcum alatosporum, isolated from Indonesian soil, is recognized by the production of salmon-colored ascomata, cylindrical asci, and hyaline, small, bicellular ascospores with walls that are verruculose and ornamented with longitudinal ridges.Heleococcum inapertum, isolated from Philippine soil, is characterized by yellow ascomata, clavate asci, and pale yellow, middle-sized, bicellular, verruculose to weakly striate ascospores surrounded with a hyaline sheath. Anamorphs of the new species are included inAcremonium. A key to the accepted species of the genus is provided.
