Revision of the genus Pseudognaphalium (Asteraceae, Gnaphalieae) in Chile

El genero Pseudognaphalium, con cerca de 90 especies de distribucion cosmopolita, es uno de los generos de la tribu Gnaphalieae con mayor numero de especies, principalmente distribuidas en America del Sur, Central y del Norte, aunque algunas tambien estan presentes en Asia y Africa. Este trabajo comprende la revision de 12 especies de Pseudognaphalium para Chile, P. aldunateoides, P. cabrerae, P. cheiranthifolium, P. cymatoides, P. gayanum, P. lacteum, P. landbeckii, P. munoziae, P. psilophyllum, P. remyanum, P. tarapacanum y P. viravira. Se incluye una clave para identificarlas y para cada una de las especies se brinda descripcion, ilustracion, fenologia, distribucion geografica y habitat, mapa de distribucion, material adicional examinado y afinidades taxonomicas. Sobre la base del estudio de los materiales tipo, se establecen los siguientes nuevos sinonimos: Gnaphalium diminutivum, Pseudognaphalium perpusillum, con P. aldunateoides; G. canum, G. ulophyllum, P. moelleri con P. cymatoides; P. heterophyllum, P. heterotrichum, G. pseudohelichrysum, P. robustum, con P. gayanum; P. glandulosum con P. psilophyllum; G. longifolium, G. subnudum, P. andicola, P. coquimbense, P. illapelinum, P. montevidense, P. pratense, con P. viravira; se designan lectotipos para las siguientes especies: Gnaphalium acutifolium, G. araucanum, G. argyrolepis, G. canum, G. cymatoides, G. glandulosum, G. heterophyllum, G. illapelinum, G. lacteum, G. landbeckii, G. moelleri, G. ramosum, G. remyanum, G. subnudum, G. tarapacanum, G. ulophyllum, G. viravira y se designa el neotipo para G. psilophyllum.

Taxonomic Studies in Pseudognaphalium Kirp. (Asteraceae, Gnaphalieae) from Peru

Abstract An account of the nine species of Pseudognaphalium occurring in Peru is provided, i.e. P. cheiranthifolium, P. dysodes, P. elegans, P. gaudichaudianum, P. lacteum, P. lanuginosum, P. luteoalbum, P. psilophyllum, and P. viravira. A number of species are placed in synonymy: Gnaphalium ecuadorense, G. ecuadorense var. boliviense, andPseudognaphalium pellitum are synonymized under P. cheiranthifolium; Gnaphalium imbaburense, G. jelskii, G. peruvianum, G. sodiroi, and Pseudognaphalium cabrerae are synonymized under P. gaudichaudianum; Gnaphalium humillimum and Pseudognaphalium dombeyanum are synonymized under P. dysodes; Gnaphalium helichrysoides and Pseudognaphalium melanosphaeroides are synonymized under P. lanuginosum; and Gnaphalium polium is synonymized under Pseudognaphalium viravira. Lectotypes are designated for Gnaphalium dombeyanum, G. elegans, G. gaudichaudianum, G. gaudichaudianum var. subrufescens, G. helichrysoides, G. jelskii, G. luteoalbum var. pallidum, G. multiceps, G. poeppigianum, and G. sodiroi. Descriptions, notes on habitat and phenology, distribution maps, full specimen citations for all taxa treated, an identification key, as well as line drawings of four of the nine species, are provided.

Pseudognaphalium munoziae (Gnaphalieae, Asteraceae): A new South American species from Chile

Pseudognaphalium is a large genus with about 90 species distributed worldwide, but with most species in America, and some in Asia, and Africa. A new species, P. munoziae , from the north of Chile (Parinacota and Iquique provinces), is described and illustrated. Pseudognaphalium munoziae is similar to P. glandulosum but it is principally distinguished by its rosulate basal leaves which are longer than the upper, all of which are apically acute to subobtuse. A key to the species of dwarf Pseudognaphalium occurring in Chile is provided along with a map of their distribution.
