Observaciones: Árbol conocido aparentemente sólo de poblaciones en el Parque Nacional Cutervo. Si bien está en un área protegida, la deforestación fuera de esta unidad de conservación podría ser una amenaza.Versión Online ISSN 1727-9933Nota del Editor: En la versión on line de este artículo han sido omitidos los mapas del Perú que ilustraban el Registro departamental.

Se realizó un estudio de la diversidad florística de los alrededores de las lagunas Pomacocha y Habascocha (4350 - 4550 m de altitud, 11°45’-11°48’S y 75°12’-75°15’O), Provincia de Concepción, Junín, Perú. Se han registrado 29 familias, 64 géneros y 100 especies. Poaceae fue la familia con mayor diversidad específica (25%), seguida por Asteraceae (24%) y Gentianaceae (6%). Se hace una comparación de la composición florística de la puna de Concepción con la de otras localidades de la puna del Perú.
Studies in theTwo species of Socotra Island and N Somalia, respectively, known as Prenanthes amabilis and P. somaliensis, are identified by molecular (ITS and matK) and morphological analyses as the closest relatives to Cichorium, hitherto considered an isolated genus of the tribe Cichorieae. To accommodate these two species, the new genus Erythroseris is established, the new combinations E. amabilis and E. somalensis are validated, and the basionym Tolpis somalensis is neotypified. Morphological differences and accordances between Cichorium and Erythroseris are discussed. It is concluded from the micromorphological results that the scaly pappus of Cichorium is homologous with the setaceous pappus as present in Erythroseris. A key to the species, illustrations of achenes, pappus and pollen, and a distribution map of the new genus are given.
Phoradendron englerianum and P. ernstianum, described by Jozef Paczoski based on Peruvian material have been recently neotypified. The original types, collected by Augusto Weberbauer in the Berlin herbarium (B) were destroyed during World War II. However, prior to these neotypifications, the two species names were inadvertently lectotypified using duplicate material for the original types kept at the Herbario Weberbauer (MOL) in Lima, Peru. Additional information on another Paczoski name, P. leucocarpum, a species transferred to Dendrophthora, is also provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
