Chemical Constituents and Biological Properties of Genus Doronicum (Asteraceae)
2021
The genus Doronicum, belonging to tribe Senecioneae (Fam. Asteraceae), is found mainly in the Asia, Europe and North Africa. This genus of plant has always been used in traditional medicinal treatments due to the many biological properties shown such as killing parasitic worms and for relieving constipation, as well as to improve heart health, to alleviate pain and inflammation, to treat insect bites, etc. According to the World Flora the genus Doronicum contains 39 subordinate taxa.[1-3] The purpose of this article, which covers data published from 1970 to 2021 with more than 110 articles, aims to carry out a complete and critical review of the Doronicum genus, examining traditional uses a…
Crassula campestris(Eckl. & Zeyh.) Endl.(Crassulaceae), a new record for the Italian flora
1998
Abstract Brullo, S., Campo, G., Marceno, C., Romano, S. & Siracusa, G.: Crassula campestris (Eckl. & Zeyh.) Endl. (Crassulaceae), a new record for the Italian flora. — Willdenowia 28: 53–58. 1998. — ISSN 0511-9618. Crassula campestris, a species widespread in S Africa, was discovered in Sicily near Palermo, which is a new record for the Italian flora. A description and illustration of C. campestris is provided and the species is compared with C. tillaea and C. basaltica, the two other Crassula species in Sicily.
A survey of the epiphytic bryophyte flora of the Rif and Tazzeka Mountains (northern Morocco)
2005
SUMMARY The catalogue of the epiphytic bryophyte flora of the Rif Mountains includes a total of 72 taxa, of which 66 are mosses and six are liverworts. Some new records are provided: Hypnum resupinatum and Tortula israelis, new to northern Africa, Antitrichia curtipendula and Cryphaea heteromalla, new to Morocco, and Dicranoweisia cirrata, Isothecium alopecuroides and Orthotrichum macrocephalum ,n ew to the Rif Mountains. Epiphytic communities in the different forest types have been analysed, with the conclusion that altitude and humidity are the main factors that determine their composition. The epiphytic stratum is best developed at the highest altitudes on the Principal chain and Tazzeka…

Plagiochasma appendiculatumLehm. & Lindenb. (Marchantiales, Aytoniaceae), a species new to the European bryophyte flora
2005
Abstract The liverwort Plagiochasma appendiculatum Lehm. & Lindenb. is reported for the first time in Europe from Mallorca (Balearic Islands, Spain). The species is described and illustrated and its distribution and ecology are discussed. Plagiochasma appendiculatum differsfromP. rupestre (J. R. Forst. & G. Forst.) Steph., the only species of the genus known at present in Europe, by characters such as the bright green or green-yellowish thallus and the orbicular and obtusescale appendages which are markedly constricted and folded at the base.
Additional reports for Italian moss flora.
2013
As a result of the study of both recent collections and a review of herbarium specimens, the following taxa are reported for the first time from various Italian regions: Hedwigia stellata Hedenas, Hedwigia ciliata var. leucophaea Bruch & Schimp., Pleurozium schreberi (Willd. ex Brid.) Mitt. and Ptychostomum compactum Hornsch. var. compactum. The last taxon is new for southern Italy, while the report of Pleurozium schreberi confirms the occurrence of this species in southern Italy after more than half a century. Moreover, Crossidium laxefilamentosum Frey & Kurschner represents the second report of this species from Italy.
First record of Ribes uva-crispa L. (Grossulariaceae) from the Madonie Mts., a new species of the Sicilian flora.
2011
Abstract In this study, a first record of Ribes uva-crispa L. (Grossulariaceae) – a new species of the Sicilian flora – from the Madonie Mts. is reported. The autochthonous and relict new population of Ribes uva-crispa L. (Grossulariaceae) is found on Mount Carbonara (Madonie Mts., North-Central Sicily), which is several hundred kilometers away from the Central Apenninic and the South Mediterranean locations of its distribution range. R. uva-crispa shows a distribution similar to other taxa extending from the Euro-Asiatic area to the mountains of North Africa with disjunct populations on the main Sicilian reliefs (Madonie and Nebrodi Mts.), testifying ancient phytogeographical connections. …
Discovery of a Lochkovian flora (Lower Devonian) in the Iberian Peninsula
2011
ABSTRACT The Lower Devonian represents an important episode in plant life history, which was marked by the diversification of land plants. Unfortunately, remains of early Devonian plants in the Iberian Peninsula are scarce. In the present paper, we describe a small assemblage of early land plants from the Lochkovian (Lower Devonian) of the Teruel Province in Spain. The main element consists of Taeniocrada-like sterile stems that are predominandy dichotomous and ribbon-like with a narrow central strand. An unidentified fossil formed by dichotomous axes together with an uncertain globular structure were also observed. This finding increases our knowledge of the palaeogeographical distribution…
