Typification and taxonomic status of Portulaca macrantha (Portulacaceae)

2010

The name Portulaca macrantha (Maire) Ricceri & Arrigoni and its basionym, P. oleracea var. macrantha Maire, from Morocco, are lectotypified. Seed micromorphology demonstrates that the species is distinct from the closely related P. papillatostellulata and P. rausii. It does not occur in Italy.

Chemical composition and herbicidal activity of the essential oil from a Cistus ladanifer population from Spain

2012

[EN] The essential oil composition of Cistus ladanifer grown in central Spain was analysed by gas chromatography and gas chromatography/mass spectrometry, revealing it to be rich in oxygenated compounds, with trans-pinocarveol (20.00%), bornyl acetate (7.03%) and terpinen-4-ol (6.37%) as the main monoterpene compounds. Viridiflorol (13.59%) and ledol (4.36%) were the main constituents of the oxygenated sesquiterpene fraction. Large amounts of-pinene (4.70%) were found in the hydrocarbonated fractions. To study its possible use as a natural herbicide, the oil was tested invitro against Amaranthus hybridus, Portulaca oleracea, Chenopodium album, Conyza canadensis and Parietaria judaica, compl…

First data on the taxonomic diversity of the Portulaca oleracea aggregate (Portulacaceae) in Iran

2017

The review of specimens from Iran belonging to the Portulaca oleracea L. aggregate resulted in the recognition of six microspecies: P. cypria Danin, P. granulatostellulata (Poelln.) Ricceri & Arrigoni, P. nitida (Danin & H.G.Baker) Ricceri & Arrigoni, P. rausii Danin, P. socotrana Domina & Raimondo, and P. trituberculata Danin, Domina & Raimondo, all reported for the first time for the flora of Iran. The identification was based on the microscopic study of seeds. It is noted that P. oleracea is not confirmed for Iran. Distribution data and an identification key for Portulaca microspecies in Iran are presented.

Data from: A revision of Sesuvium (Aizoaceae, Sesuvioideae)

2017

Sesuvium and Cypselea are closely related succulent genera within the Sesuvioideae (Aizoaceae). Since Cypselea is nested in Sesuvium in molecular studies and both genera share traits separating them from other members of the subfamily, we propose to include Cypselea in Sesuvium. Sesuvium (incl. Cypselea) comprises 14 species and is distributed worldwide with centres of diversity in southern Africa and North and Central America. Sesuvium comprises erect to procumbent herbs with opposite leaves that often bear conspicuous sheath-like lateral appendages on the petioles (pseudostipules). These and the many-seeded capsules are diagnostic traits, separating Sesuvium from the closely related gener…

Caratterizzazione degli acidi grassi nell’olio dei semi di Portulaca oleracea L.

2021

La Portulaca (Portulaca oleracea L.) è una pianta erbacea annuale con steli rossastri e foglie alternate della famiglia Portulacaceae. Si adatta ad ambienti diversi, anche marginali, caratterizzati da siccità e salinità dei suoli. È una pianta ben nota nella medicina tradizionale del bacino del Mediterraneo come diuretico, febbrifugo, antisettico, antispasmodico, vermifugo e svolge attività di anticolinesterasica. Questi effetti sono principalmente attribuiti ai suoi costituenti fenolici e ai diversi acidi grassi, specialmente all’acido α-linolenico che rappresenta quasi il 30% degli acidi grassi essenziali. A parte l’acido αlinolenico, sono stati rilevati in tessuti vegetali anche altri ac…
