Taxonomic investigations on Psoralea palaestina (Fabaceae), a critical species of Mediterranean flora
2016
Psoralea palaestina is a critical and unappreciated species described from Palestinian territories, and currently treated as synonym of P. bituminosa, nowadays known as Bituminaria bituminosa. Nomenclatural investigations allowed to ascertain that it was validly described for the first time by Bassi (1768) and not by Gouan (1773), as previously thought. Extensive taxonomic investigations revealed that this very peculiar legume is morphologically well differentiated from the other allied known species. Therefore, it has to be properly treated at specific level and transferred to the genus Bituminaria, thus proposing a new combination: Bituminaria palaestina. Based on literature, herbarium an…
New populations of the threatened fern Equisetum moorei Newman in the Valencian Community (Spain)
2020
Se aportan nuevas citas del helecho amenazado Equisetum moorei en la Comunidad Valenciana, donde solo se conocían previamente seis localidades con presencia actual de la especie. Una de las nuevas poblaciones amplía notablemente el área de distribución conocida en esta región, ya que la mayor parte de las localidades conocidas se concentraban en el macizo del Peñagolosa (provincia de Castellón). Se describen las características ecológicas y demográficas de las nuevas localidades en el contexto de las poblaciones previamente conocidas en la región valenciana.
Precisiones corológicas y taxonómicas sobre la flora de Alicante
2007
Se presentan datos sobre la distribución y ecología de táxones nuevos o poco conocidos de la flora vascular de Alicante. Se aportan nueve primeras citas concretas para la flora provincial, siendo tres de ellas novedades asimismo para la Comunidad Valenciana. Además, se proponen dos nuevas combinaciones: Nepeta mallophora subsp. bourgaei (Briq.) M.B. Crespo, Camuñas & J.C. Cristóbal, y N. mallophora subsp. anticaria (Ladero & Rivas Goday ex Ubera & Valdés) M.B. Crespo, Camuñas & J.C. Cristóbal. Data are reported on distribution and ecology of new or poorly known taxa of Alicante province (E of Spain). Nine species are cited for the first time in that territory, being three of them also new f…
Allium makrianum (Alliaceae), a new autumnal species from Greece
2010
Allium makrianum is described as a new species growing on the limestone of the Chios, north-eastern Aegean island (Greece). It is a very rare autumnal geophyte, showing some relationship with A. archeotrichon from Rhodos. Its iconography, morphology, chromosome number (2n=16), leaf anatomy, ecology and taxonomy are examined.
New national and regional plant records: Contribution to the flora of the Old World countries
2023
is paper presents new data on the occurrence of 16 vascular plant species from five Eurasian countries obtained during field explorations, as well as during taxonomic revisions of herbarium materials. Five taxa (Draba fladnizensis, Gentiana orbicularis, Helianthus giganteus, Symphyotrichum cordifolium, alictrum alpinum) are recorded for the first time from Poland, five (Achnatherum jacquemontii, Arrhenatherum elatius, Dittrichia graveolens, Geranium pyrenaicum, Stipa × balkanabatica) from Tajikistan, three (Achnatherum sibiricum, Asyneuma thomsonii, Stipa × balkanabatica) from Kyrgyzstan, one (Orobanche bartlingii) from Turkey, one (Calamagrostis obtusata) from China and one (Calamagrosti…

Prospero hierae (Hyacinthaceae), a New Species from Marettimo Island (Sicily)
2009
A new species, Prospero hierae C. Brullo, S. Brullo, Giusso, Pavone & Salmeri (Hyacinthaceae), from Island of Marettimo (Egadi Archipelago, Sicily) is described and illustrated. Its chromosome number (2n = 14), leaf anatomy and ecology are examined. This small species with glaucous, adaxially flat leaves is closely related with the taxa belonging to the Prospero autumnale group and, in particular, it shows more affinities with P. corsicum, P. pulchellum and P. minimum.
Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 2
2014
The paper presents new records for 20 vascular plant species from eight Asian and two European countries. Five taxa (Artemisia campestris, Artemisia tanacetifolia, Delphinium sajanense, Diarthron vasiculosum var. undulatum, Epilobium adenocaulon) are reported from Kazakhstan, four (Deyeuxia yanyuanensis, Poa arnoldii, Stipa gracilis, Stipa macroglossa subsp. kazachstanica) from China, three (Nepeta pamirensis, Silene bucharica, Scrophularia pamiro-alaica) from Uzbekistan, two (Epilobium nervosum, Stellaria zolotukhinii) from Mongolia, two (Oenothera deflexa, Scirpus georgianus) from Poland, one (Coronopus didymus) from Tajikistan, one (Orobanche rumseiana) from Italy, one (Stipa macroglossa…
Chorological notes on the Sicilian endemic Euphorbia papillaris (Euphorbiaceae)
2022
Thanks to the discovery of a new important site in the Trapani Mountains, the distribution of Euphorbia papillaris, a rare plant endemic to N-W Sicily, is revised. On the basis of the unpublished record, one of the two hypotheses on the discovery of the species in Sicily, previously advanced, is here confirmed. Floristic and ecological information on the new locality are also provided.
<i>Santolina ageratifolia</i> Bamades ex Asso (<i>Compositae</i>) and their relationships with <i>S. rosmarinifolia<…
1997
The status of Santolina ageratifolia Bamades ex Asso as a distinct species belonging to S. rosmarinifolia L. aggr. is vindicated. An historical approach, a revision of the diagnostic characters and a detailed chorology of the species in Spain is presented. Likewise, some doubtful questions conceming taxonomy and chorology in Spain of the whole aggregate (including S. rosmarinifolia L. s. str., S. canescens Lag., S. pectinata Lag. and S. semidentata Hoffmanns. & Link) are clarified. A new nomenclatural combination is proposed: S. semidentata subsp. melidensis (Rodriguez-Oubina & Ortiz) Lopez Udias, Fabregat & Mateo.
