The genus Santolina (Asteraceae, Anthemideae) includes 26 species of aromatic evergreen shrubs endemic to the western Mediterranean Basin. Santolina is widely used as ornamental plant, in xerigardening, and in ethnobotany. The Santolina chamaecyparissus complex, including about half of the known species diversity, has been properly investigated on...
A traditional karyomorphological approach was carried out in order to investigate the cytotaxonomic relationships among the species of the Santolina chamaecyparissus complex. All the 14 species included in this species complex were analysed for a total of 39 populations. Metaphase plates were obtained by squashing root tips stained with Feulgen tec...
Aims
Serpentine soils are rare globally, covering <1% of the land surface, but frequently harbouring large numbers of narrow endemic species. Many serpentine areas are endangered and would benefit from actions informed by species distribution models (SDMs). Here, we assessed, for the first time, the potential use of remotely sensed descriptors of w...
Santolina treatment in Flora Iberica
Traballo desenvolvido para Observer Turismo Científico e con financiamento da deputación de Lugo. Unha guía divulgativa para aproximarse aos valores naturais e culturais das montañas de Ancares e Courel
An alphabetical list of all the validly published names of taxa in Erythrocephalum (Asteraceae: Dicomeae) is presented with details of all types of which four are new lectotypifications and three new neotypifications. The names first published in Achyrothalamus and Haemastegia are also included. All names are assigned to their accepted taxa in this...
The genus Santolina is represented in the Iberian Peninsula and Balearic Islands mainly by two complexes of species: S. rosmarinifolia aggr. and S. chamaecyparissus aggr., with a great similarity between the taxa included in each of these complexes. In the study of Santolina for the “Flora iberica” project, we prefer the species rank for the taxa w...
The Rand Flora is a well-known floristic pattern in which unrelated plant lineages show similar disjunct distributions in the continental margins of Africa and adjacent islands—Macaronesia-northwest Africa, Horn of Africa-Southern Arabia, Eastern Africa, and Southern Africa. These lineages are now separated by environmental barriers such as the ari...
A molecular phylogenetic study of the African Mutisieae s.l. (Asteraceae) was performed using the chloroplast markers ndhF and trnL-F. The sequences of 46 species, including three representatives of Cynareae (Cardueae), were analysed applying maximum parsimony and Bayesian inference, with Mutisia and Hecastocleis as outgroups. Four main clades corr...
Os livros vermelhos são essenciais na identificação e monitorização de táxones ameaçados e assumem uma importância acrescida quando são produzidos nos níveis hierárquicos mais baixos, já que permitem aos gestores priorizar as medidas de conservação da biodiversidade a nível local. No entanto, existem algumas dificuldades relativas à produção de liv...
To better understand the taxonomy and phylogeny of the genus Omphalodes (Boraginaceae), the pollen morphology of 23 species encompassing all major geographical and morphological groups was studied from acetolysed pollen grains using light and scanning electron microscopy. Three pollen types were distinguishable through apertural morphology and scul...
En el año 2000 salió publicada la última Lista Roja sobre las plantas vasculares españolas, que evaluaba sus amenazas en todo el país según las categorías de la Unión Internacional para la Conservación de la Naturaleza (UICN) reformadas en 1994, más cuantitativas y objetivas. Aquel documento dio a conocer la situación de riesgo de 1.414 especies y...
During a stay at the Kirstenbosch Research Centre in Cape Town, South Africa, in 2002, the first author studied a collection of Polygonum L. (Polygonaceae) from Springbok (Namaqualand, Northern Cape, South Africa), which was identified as a new species. In addition to the description of the new species, Polygonum snijmanii, we discuss its relation...
