Notas taxonómicas y distributivas sobre Serapias lingua subsp. tunetana (Orchidaceae), una rara espècie endémica de Túnez
Get PDFSerapias 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. tunetana, una rara orquídea endémica con área de distribución restringida en Túnez, al norte de Túnez, ha sido redescubierta lejos de su localidad tipo después de 22 años. Desde su primer hallazgo en 1996 y su descripción publicada en 2005, la subespecie no se había encontrado nuevamente y se presume que se extinguió o fue identificada erróneamente. En este trabajo se proporciona una descripción detallada de la subespecie que justifica una enmienda a su descripción, y se aporta asimismo un mapa de distribución y varias fotografías. Se listan las principales afinidades de la subsp. tunetana con los táxones más estrechamente relacionados dentro del grupo de S. lingua que se distribuyen en Túnez. Se evalúa su estado de conservación atendiendo a los criterios y categorías de la UICN

Studies on the genus Atriplex (Chenopodiaceae) in Italy. VIII. Names published by Vincenzo Tineo and Michele Lojacono-Pojero
Get PDFThe typification of the Atriplex names published by Vincenzo Tineo and Michele LojaconoPojero is discussed. Atriplex ambigua, A. dealbata, A. graeci, A. halimoides, A halimoides var. glomerata, A. halimoides var. perglauca, A. polyphylla, and A. ratundifolia are neo- or lectotypified on specimens preserved at FI or PAL and
ynonymized with A. glauca (= A. dealbata), A. halimus (= A. halimoides = A. halimoides var. glomerata = A. halimoides var. perglauca), A. rosea (= A. ambigua = A. graeci) and A. tornabenei (= A. polyphylla = A. rotundifolia). The Tineo’s A. arenaria, previously considered as replaced synonym of A. tornabenei, is clarified
and typified (neotype) on a specimens deposited at FI
The floristic research in Italian archaeological sites
Get PDFIn Italy occur about 240 archaeological areas or parks and more than 1500 main monumental complexes;
the number of individual monuments would exceed several thousand. The interest on the
flora of archaeological sites in Italy dates back to the XVII Century. The scope of floristic inventories
can be limited to the mere list of the plants growing into the area or this list can be accompanied
by indication of the dangerousness for the monument represented by single species and the indications
for their management. For this review the basic references concerning the flora of archaeological
sites located in Italy were listed and classified by publication date, area, and main historical period
or civilization to which the complex refers.
Overall 96 references have been collected (73 full articles, 10 chapters of book and 13 conference
abstracts) referring to 47 sites. The large part of these contributions was published between 1990 and
1999. The most investigated regions are Lazio and Sicily. The complexes belonging to the Roman
civilization were the most studied. This even if, in many cases, it is not easy to attribute a monument
to a precise historical epoch because different buildings, over time, have been re-adapted and used
by the civilizations that have succeeded each other. From what has been stated above it is evident
that the botanical prospecting in archaeological areas is still very limited, lacking entirely in several
regions. With the exception of the single Flavian Amphitheatre in Rome (the Colosseum), which has
become a case study, there are no studies published on most of the sites and monuments in Italy. This
review can be a stimulus for scholars and managers in order to undertake targeted campaigns of
prospecting of the biological component occurring in these areas and of deepening knowledge on its
management in order to preserve this historical and artistic heritage
Typification of the name Lavatera agrigentina (Malvaceae)
No full textAs part of an ongoing study on the names of vascular plants described from Sicily (Southern Italy), a nomenclature investigation on the name Lavatera agrigentina Tineo, basionym of Malva agrigentina (Tineo) Soldano, Banfi & Galasso in Banfi et al., which appears to be yet untypified, is here presented
Wedelia glauca (Asteraceae) a new naturalized alien to Italy
Get PDFWedelia glauca (Ortega) Blake (Asteraceae), perennial herb native to the tropical regions of South America, was found naturalized in the suburbs of Palermo (Sicily). This is the first report to Italy. In Europe this plant is known from Spain and Portugal
