Imidazolium Based Ionic Liquids: A Promising Green Solvent for Water Hyacinth Biomass Deconstruction.
2018
Water hyacinth (WH) is a troublesome aquatic weed of natural and artificial water bodies of India and other tropical countries and causing severe ecological problems. The WH biomass is low in lignin content and contains high amount of cellulose and hemicellulose, making it suitable material for conversion into liquid fuels for energy production. This study highlighted that, how different imidazolium based ionic liquids (ILs) [1-alkyl-3-methylimidazolium bromide, [Cnmim]Br (n = 2, 4, 6, 8, and 10)] with tunable properties can be employed for the degradation of WH biomass. Different characterizations techniques, such as XRD, FT-IR, SEM, and DSC are used to unravel the interplay between ILs an…
Loncomelos koprulense (Asparagaceae), a new species from southern Turkey
2021
A new species, Loncomelos koprulense (Asparagaceae), is described and illustrated from southern Turkey. It is a very rare endemic species growing on small semi-rocky escarpments within the Köprülü Kanyon in the province of Antalya. Morphologically for its hairy leaves, L. koprulense shows some relationships with L. malatyanum and L. tardum, species localized in Anatolia too. The chromosome number of the new species is 2n = 2x = 22. Geographical distribution map for L. koprulense, L. malatyanum and L. tardum is provided.

Prospero hierae (Hyacinthaceae), a New Species from Marettimo Island (Sicily)
2009
A new species, Prospero hierae C. Brullo, S. Brullo, Giusso, Pavone & Salmeri (Hyacinthaceae), from Island of Marettimo (Egadi Archipelago, Sicily) is described and illustrated. Its chromosome number (2n = 14), leaf anatomy and ecology are examined. This small species with glaucous, adaxially flat leaves is closely related with the taxa belonging to the Prospero autumnale group and, in particular, it shows more affinities with P. corsicum, P. pulchellum and P. minimum.
Uptake prediction of nine heavy metals by Eichhornia crassipes grown in irrigation canals: A biomonitoring approach
2021
The principal objective of this study is to generate mathematical regression equations that facilitate the estimation of the extent to which Eichhornia crassipes (C. Mart.) Solms, water hyacinth, absorbs heavy metals (HMs) into four plant organs (laminae, petioles, roots, and stolons). This study considers the absorption of nine HMs (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn), and the E. crassipes evaluated in this study were located in three irrigation canals in the North Nile Delta in Egypt, with sampling being conducted in both monospecific and homogenous E. crassipes. Samples of both E. crassipes and water were collected on a monthly basis during one growing season. Analysis of the water s…

1997
Se aportan datos diversos sobre los táxones del género Urginea Steinh. (Hyacinthaceae) presentes en la flora ibérica. Se propone la combinación Urginea undulata subsp. caeculi (Pau) M.B. Crespo & Mateo comb. nov., para las poblaciones ibéricas de la especie, y se tipifica dicho nombre. Además, se añade una clave para la identificación de los táxones considerados. Some data on taxa of Urginea Steinh. (Hyacinthaceae) found in the Iberian flora are reported. The combination Urginea undulata subsp. caeculi (Pau) M.B. Crespo & Mateo comb. nov., is proposed for the Spanish populations of the species, and that name is also typified. Moreover, a key is presented for identification of taxa.
Hyacinthoides kroumiriensis sp.nov. (Hyacinthaceae): a new species from North West of Tunisia
2014
Hyacinthoides kroumiriensis El Mokni, Domina, Sebei& El Aouni, a new species in Hyacinthaceae from Kroumiria region, North West of Tunisia, is described and illustrated. Morphological characteristics with illustrations, habitat and description of the new species are provided, in addition to a diagnostic comparison with one phenotypically similar species within the same clade.
Indagine biosistematica su Scilla sensu lato in Italia e generi affini
2008
The taxonomic assessment of the genus Scilla s.l. and its related genera growing in Italy is defined based on literature data and our own morphological, karyological and phenological studies. A cladistic analysis is also performed in order to test taxonomic role of the selected diagnostic characters. Results agree with the most recent revisions and give support for the proposed synoptical key.

The Ability of Water Hyacinth (Eichhornia crasipes Mart.) and Water Lettuce (Pistia stratiotes Linn.) for Reducing Pollutants in Batik Wastewater
2021
Batik produced by craftsmen is categorized as a small and medium industry. The problem of Batik production is less attention to the environment because the craftsmen lived in the middle of a residential area that has inexperience. One of less attention to the environment is no treatment of wastewater that reaches up to 95 % (61.9 L each cloth). Thus it polluted the river. This research aimed to treat the wastewater of Batik production by using phytoremediation. In this study, phytoremediation was carried out in three tanks in series using Eichhornia crassipes and Pistia stratiotes which are abundant in Indonesia. The treated wastewater was evaluated for its ammonia and chromium (Cr). The re…
