Orobanche australis Moris ex Bertol. the correct name for O. thapsoides Lojac. (Orobanchaceae)
2022
The taxonomic relationships between Orobanche australis and O. thapsoides are analyzed through the study of the original material. These species are also compared with other morphologically similar ones occurring in the Mediterranean (O. canescens, O. pubescens, O. palaestina, O. amethystea). The lectotype of O. palaestina is designated. From the comparison of these taxa it is evident that O. australis and O. thapsoides refer to the same taxon, to which the name O. australis must be given by priority. The distribution of this species includes Sardinia, Sicily, Peninsular Italy and Southern France. It grows on pastures from the sea level to about 1000 m of altitude, host of Asteraceae. An id…
New records of the genus Orobanche L. (Orobanchaceae) to the Tunisian flora with lectotypification of the name O. rapum-genistae Thuill.
2023
Based on several field surveys and on the study of original material, we have identified three new species of Orobanche L. s.s. (Orobanchaceae) new to the flora of Tunisia. Orobanche alba Willd., O. calendulae Pomel, and O. gracilis Sm. are reported as new for the country, and the occurrence of O. rapum-genistae Thuill. is confirmed. The lectotypification of O. rapum-genistae is here proposed with a specimen housed in Genève (G). The geographical distribution of the four taxa in Tunisia is given, and details of habitats and hosts are provided. Altogether, the genus Orobanche in Tunisia now includes 18 species; a dichotomous key is proposed to facilitate the identification of these taxa.
The genus Capparis L. (Capparaceae) in Laos and Cambodia
2023
SummaryA taxonomic revision of the genus Capparis in Laos and Cambodia was undertaken. Based on examination of historical and recent herbarium collections coupled with field investigations, 25 species and 7 intraspecific taxa, all belonging to sect. Monostichocalyx, were recognised in the study area. Among these, a new species, C. averyanovii, and a new subspecies, C. acutifolia subsp. thamphae, from central and northern Laos are described and illustrated. A key to the species is provided, along with descriptions, synonyms, distribution ranges, autecological and phenological data, and 31 lectotypes are selected. When available, vernacular names and traditional uses of the species are also g…
VERBENA BONARIENSIS (VERBENACEAE) ADVENTIVE IN ITALY
2014
Among the species of Verbena L. cultivated in Italy Traverso (1) reports: V venosa Gilles, V tenera Sprengel (= V. pulchella Sweet.) and the horticultural hybrid V I?Jbrida Hort. (=V. hortensis Hort.). No trace of V. bonariensis L., that is reported about 60 years later as naturalized in Tuscany (2). In the Herbarium Centrale !talcum (Fl) are housed specimens collected in Piedmont and Tuscany, labelled as V. venosa - taxon considered a variety of V. bonariensis. V. bonariensis, as indicated by the specific epithet, is a South American species, herbaceous, usually perennial, also cultivated as an ornamental. Several varieties and wild lforms are known of this taxon. The International Plant N…

La componente terofitica della flora della Sardegna. Forme di crescita, ecologia, corologia e sinsistematica
2004
Nel quadro di una ricerca finalizzata all’incremento delle conoscenze sulla flora e vegetazione terofitica della Sardegna, viene presentata una check-list aggiornata delle specie annuali presenti sull’isola, frutto dell’integrazione di dati bibliografici con indagini condotte sul campo. Il presente lavoro è stato realizzato con l’intento di aggiornare le informazioni relative a corologia, forme di crescita, strategie di disseminazione, periodo di fioritura, colorazioni antesiche, habitat preferenziali e rarità delle specie terofitiche finora segnalate per la Sardegna.
