The Olea europaea L. var. sylvestris (Mill.) Lehr. forests in the Mediterranean area
2019
This paper examines the forest communities dominated by Olea europaea L. var. sylvestris (Mill.) Lehr. that have been described up until now in the Mediterranean Region (including other isolated extrazonal areas in the northwestern Iberian Peninsula and in Northern Turkey) as more or less evolved aspects of woods, microwoods and high maquis that principally tend to make up climacic and edapho-climacic “series heads”. These forma- tions maintain a significant large-scale distributive potential within the infra- and thermomediterranean bioclimate belts (with a few penetrations into the mesomediterranean) with a dry-subhumid (and sometimes humid) ombrotype; however, they are currently quite ra…
Silene nefelites (Caryophyllaceae) a new annual species from Sicily
2014
A new species of Silene sect. Dipterosperma, named S. nefelites C. Brullo, S. Brullo, Giusso & Ilardi spec. nova, from Sicily is described and illustrated. Some of the characteristics are pinnately nerved leaves, 10–25 mm long bracts and 10– 15 mm long filaments. It is a therophyte occurring on the top of Mt. Erice, near Trapani, where it grows on calcareous rocky stands. Its relationships with S. colorata and allied species are also examined. A key to the Sicilian species belonging to S. sect. Dipterosperma is provided Eine neue Art von Silene sect. Dipterosperma, nämlich S. nefelites C. Brullo, S. Brullo, Giusso & Ilardi spec. nova von Sizilien wird beschrieben und illustriert.

Silene crassiuscula (Caryophyllaceae), a new species from Sicily
2015
Silene crassiuscula,, a new species of S. sect. Dipterosperma, is described and illustrated from North-Western Sicily. It is an annual halophyte with succulent growing on carbonatic or calcarenitic rocks of coastal stands. From the morphological point of view , S. crassiuscula appears to be similar to the species belonging to the S. colorata group especially to S. nummica, from Sardinia, from which it differs in several features chiefly regarding the habit, leaves, inflorescences, floral pieces and seed micro-morphology. An analytical key of the taxa belonging to this section is also provided.
Three new Spanish species of Biscutella L. (Brassicaceae) and remarks on B. valentina (L.) Heywood
2000
Abstract Three new species are described in Biscutella sect. Biscutella from the central-eastern mountains of the Iberian Peninsula B. bilbilitana Mateo & M.B. Crespo, B. segurae Mateo & M.B. Crespo, and B. conquensis Mateo & M.B. Crespo. They are characterized morphologically, ecologically and chorologically. Data separating them from B. valentina (L.) Heywood, a taxon to which they sometimes have been referred, are also reported.
Anotaciones sobre Lasiopogon muscoides (Desf.) DC. (Compositae) en la Comunidad Valenciana
2014
Se dan a conocer nuevos datos sobre Lasiopogon muscoides, planta autóctona de la flora de la Comunidad Valenciana (E de España), en cuyas comarcas centrales alcanza su límite septentrional de distribución. Se aporta por primera vez información concreta sobre su ubicación y su comportamiento ecológico y fitosociológico. Además, dada su rareza y originalidad en el conjunto de la flora de este territorio, se propone su inclusión en el Catálogo Valenciano de Especies de Flora Amenazadas con la categoría “en peligro de extinción”. New data are reported on Lasiopogon muscoides in the Valencian Community (E of Spain), a territory in which its northernmost distribution is found. Data are shown for …
Sobre Teucrium × bicoloreum (Lamiaceae) y sus afinidades taxonómicas con algunos congéneres presentes en el territorio valenciano
2009
Se reivindica el nombre Teucrium × bicoloreum Pau ex C. Vicioso para el nototaxon producto del cruce natural entre T. expassum Pau y T. ronnigeri Sennen. Se comentan las relaciones morfológicas con ambos parentales y las afinidades taxonónicas con aquellos congéneres más estrechamente emparentado. Esta nueva interpretación permite separar a las plantas valencianas respecto del complejo de formas de distribución bética, tradicionalmente adscritas a T. bicoloreum auct. pl. non Pau ex C. Vicioso. Se aportan nuevos datos sobre su presencia en la Comunidad Valenciana y algunos aspectos relacionados con su ecología. Además, se describen dos nuevas notoformas: T. × bicoloreum nm. expassoides y nm.…

Fern-dominated Rock Plant Communities of Tajikistan (Middle Asia)
2015
The results of phytosociological research conducted on the fern vegetation of rock crevices and clefts of the Pamir-Alai Mountains in Tajikistan are presented. During field surveys done in 2010–2013, 78 phytosociological relevés were sampled. Plant species were recorded according to the Braun-Blanquet cover-abundance scale. A synopsis of the fern communities of the montane and high altitude zones in Tajikistan is proposed. In the examined vegetation plots, species of 9 ferns, 58 angiosperms and 13 mosses were recorded. The most frequent ferns were: Cystopteris fragilis, Cheilanthes persica, Asplenium ruta-muraria, Asplenium ceterach, Adiantum capillus-veneris and Cryptogramma stelleri. Six …

Notas taxonómicas y distributivas sobre Serapias lingua subsp. tunetana (Orchidaceae), una rara espècie endémica de Túnez
2019
Serapias lingua subsp. tunetana, a rare endemic orchid confined to Tunis, northern of Tunisia, has been rediscovered far away from its type locality nearly after 22 years. Since its first finding in 1996 and its description published in 2005, the subspecies has not been found again, and was presumed to be extinct, or the taxon was erroneously identified. A detailed description of the subspecies justifying an amendment to its description, a map of its current distribution and colour photographs are also provided. The affinities to the related taxa within the S. lingua group occurring in Tunisia are here presented. The global IUCN status for this taxon is evaluated. Serapias lingua subsp. tun…
