Linaria pseudamethystea, from the south-western part of the Iberian Peninsula, is here newly described, illustrated, and compared with its morphologically closest relatives from L. sect. Supinae: L. amethystea, L. semialata, and L. diffusa. The species is characterized by being annual and glabrous and by having a loose inflorescence; calyx lobes unequal; corolla blue-violet, with conspicuous dark veins and yellow to orangish palate, abaxial lip with two prominent humps and ornamentation reticulate and often with two thick spots, and spur equalling the length of the rest of the corolla, curved, usually dark blue-violet; capsule globose and glabrous; seeds black with densely papillose and non-tuberculate disk, and non- thickened wing. L. pseudamethystea is an endemic species, whose general morphology and distribution area overlap with that of L. amethystea, causing confusion between the two species and misidentification of their populations. The new species grows in ephemeral therophyte pastures of siliceous mountains, from the east of the province of Seville (Spain) to the Algarve and Alentejo (Portugal).
Linaria subbaetica, a new species from the south of the Iberian Peninsula, is here described, illustrated, and compared with its morphologically closest relatives from L. sect. Supinae: L. badalii, L. caesia, and L. supina. The species is characterised by being annual, and having usually revolute leaves, a short and corymbiform inflorescence at anthesis with a pilose-glandulose axis, a white to pale-yellow corolla (yellow to orangish palate), bearing a spur equalling to slightly longer that the rest of the corolla, and black seeds with a tuberculate and papillose disc surface and a thickened wing. L. subbaetica is an endemic species, growing on calcareous mountains, in the Sierras Subbéticas Natural Park, Córdoba province (Andalusia, Spain).

Se cita por primera vez en la Península Ibérica y en Europa Occidental la presencia de Eremopyrum orientale (L.) Jaub. & Spach, un taxon anual que se desarrolla en los medios semiáridos de la Hoya de Guadix (Granada). Las características ambientales propias de estos ambientes (sustratos poco favorables para el desarrollo de la vida vegetal junto a una alta irregularidad intra e inter anual de las precipitaciones) parecen ser la causa de no haber sido localizada hasta ahora. Esas mismas características ambientales y la, aparentemente imparable, expansión de las actividades antropocéntricas nos hacen considerar este taxon como amenazado bajo la categoría de En Peligro (EN) con el criterio: A4ac; B1ac(i,ii,iii,iv)+2ac(i,ii,iii,iv)Key words: Flora, Europa, Poaceae, Eremopyrum.Palabras clave: Flora, Europa, Poaceae, Eremopyrum.
ResumenSe han elaborado dos listas Top Ten de plantas vasculares amenazadas en Andalucía Oriental, una para los 10 taxones endémicos y otra para los 10 no endémicos. Para ello se ha evaluado el estado de conservación de 275 taxones de plantas a partir de la gran cantidad de información generada en los últimos años, utilizando 6 criterios a los que se asignan valores numéricos: número de individuos, número de poblaciones, tendencia poblacional, nivel de endemicidad, grado de protección legal y valor ecológico. Entre los 111 endémicos, las tres especies más amenazadas son Verbascum prunellii, Gadoria falukei y Echinospartum algibicum, aunque las más preocupantes en cuanto a su evolución reciente son Laserpitium longiradium, Limonium estevei y Tephroseris elodes. Entre los 164 no endémicos analizados, las tres especies más amenazadas son Nepeta hispanica, Centaurea dracunculifolia y Polygala balansae. Las amenazas principales en el conjunto del Top Ten derivan del escaso número de poblaciones y efectivos existentes, la fragilidad y singularidad de los hábitats sobre los que se asientan, así como de las alteraciones antrópicas, entre las que cabe destacar los efectos negativos del cambio climático, la transformación de uso del suelo y el sobrepastoreo. La comparación de los listados obtenidos con los catálogos legales muestra un desfase importante, ya que el 61% de los taxones más amenazados en la actualidad para Andalucía Oriental carecen de protección en la legislación vigente. Abstract Top Ten of most threatened plants in eastern Andalusia: endemic and nonendemic taxaTop Ten lists of threatened vascular plants have been drawn up in eastern Andalusia, one for the 10 endemic taxa and one for the 10 non-endemic ones. The conservation status of 275 taxa of plants has been evaluated from the large amount of information compiled in recent years, using 6 criteria to which numerical values are assigned: number of individuals, number of populations, population trend, endemicity level, degree of legal protection, and ecological value. Among the 111 endemics, the three most threatened species are Verbascum prunellii, Gadoria falukei, and Echinospartum algibicum, although the most worrying in terms of their recent trends are Laserpitium longiradium, Limonium estevei, and Tephroseris elodes. Among the 164 non-endemic taxa analyzed, the three most threatened species are Nepeta hispanica, Centaurea dracunculifolia, and Polygala balansae. The main threats for the entire Top Ten list concern the low number of existing populations and individuals, the fragility and singularity of their habitats, as well as anthropogenic alterations, among which the negative effects include climate change, land-use change
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.
