Seed morphology of Linaria species from eastern Spain: identification of species and taxonomic implications
2001
Abstract Seed morphology of 15 taxa of Linaria from eastern Spain has been studied using stereoscopic and scanning electron microscopy. Four different morphological types are described according to features of the seed-coat surface. The type that includes winged seeded taxa is divided into three subtypes. Seed morphology of each type and subtype is described, compared, illustrated and discussed according to its taxonomic and biological implications. A key to identify the different species or groups of species is also supplied.
Lectotypification of the names of two species of Fumana ( Cistaceae )
2004
The names Cistus ericoides Cav. and C. laevis Cav. are typified. These names apply to two species, currently classified within the genus Fumana (Dunal) Spach, but the names have been frequently misapplied and both of thempose typification problems. The type specimen of the first has not been found. Thus an illustration is chosen as type and an epitype designated. The original material of C. laevis comprises a mixture of two different species. One element is selected to clarify the application of this binomial.
A new species of <em>Metapyroppia</em> Woolley, 1969 (Acari, Oribatida, Peloppiidae) from Nepal
2014
A new species of oribatid mites of the family Peloppiidae, Metapyroppia gigantea n. sp. , is described from Nepal. The genus Metapyroppia is recorded for the first time from the Oriental region. Metapyroppia gigantea n. sp. differs from the type species, Metapyroppia doratosa Woolley, 1969, by the absence of notogastral setae c 2 and c 3 , presence of pointed rostrum and the adanal lyrifissures distanced from the anal plates. The morphology of gnathosoma and legs are presented in detail for the first time for any member of this genus. urn:lsid:zoobank.org:pub:EEE741F4-4C86-4625-B3FD-48E1DDA1D2D3
Effects of plant species in a horizontal subsurface flow constructedwetland – phytoremediation of treated urban wastewater withCyperus alternifolius …
2013
Abstract Plant species carry out a series of important biological, chemical and physical processes within a constructed wetland wastewater treatment system and make a significant contribution to wastewater purification. This paper compares two emergent macrophytes – Cyperus alternifolius L. and Typha latifolia L. – planted separately in a pilot horizontal subsurface flow system for the phytoremediation of treated urban wastewater in the West of Sicily (Italy). The total surface area of the three units within the pilot system was 99 m 2 . Six subunits were planted with two species and three subunits were left unplanted as the control. The main aim of the study was to demonstrate that, under …
