Imaging Technologies – From Intravital Microscopy to Molecular Analyses

Nodosilinea epilithica Perkerson et Casamatta is reported for the first time for Russia. The sample was isolated from a typical chestnut soil in the zone of dry steppes (Volgograd Region) and its identity was confirmed by morphological and molecular analyses. The specific feature of the studied strain is its ability to form nodules at normal (60–75 μmol photons ∙ m-2 ∙ sec-1) light. The number of nodules is supposed to be related to the age of a cyanobacterial culture.

Taxonomic Studies

Psychotria subg. Heteropsychotria Steyerm. has been shown by morphological and molecular analyses to be polyphyletic. Most of its species, including its type, belong to Palicourea Aubl. (“Pal.”). Thirty-two species of this group are reviewed here, and 17 species in Psychotria L. are transferred to Palicourea and one to Rudgea Salisb. Two replacement names, Pal. agudeloana C. M. Taylor and Pal. tabayensis C. M. Taylor, are published. Taxonomic studies here clarify circumscriptions of similar, often-confused species for several distinctive species groups found variously in Mesoamerica and the Andes: the Palicourea aschersonianoides group, the Palicourea galeottiana group, the Palicourea sulphurea group, and the Palicourea tristis group. Three new species of Palicourea are described: Pal. aschersonianula C. M. Taylor, Pal. gonzaleziana C. M. Taylor, and Pal. wachterae C. M. Taylor. Nineteen names are newly typified, and infrageneric classifications are noted for the species of Palicourea studied.
