Karyological and taxonomic notes on Cytisus Desf. Sect. Spartopsis Dumort. and Sect. Alburnoides DC. (Genisteae, Leguminosae) from the Iberian Peninsula and Morocco

Karyological information on Cytisus species indicates at least two chromosome numbers for most of the taxa. This instability is, a striking karyological feature of Cytisus . Chromosome numbers of taxa in Sect. Spartopsis and Sect. Alburnoides, both well represented in Morocco and the Iberian Peninsula, are presented here. We provide the first data on chromosome numbers for the Moroccan taxa: C. grandiflorus subsp. barbarus , and subsp. haplophyllus (n = 23, 2 n = 46) , C. maurus (2 n = 48), C. megalanthus ( n = 23), C. arboreus subsp. arboreus , subsp. baeticus , and subsp. catalaunicus (2 n = 50), C. valdesii ( n = 23 ). New populations from the Iberian Peninsula have been counted: C. grandiflorus subsp. grandiflorus (2 n = 46), C. scoparius subsp. scoparius ( n = 23) , C. striatus subsp. eriocarpus ( n = 23, 2 n = 46), C. multiflorus (n = 23), C. oromediterraneus ( n = 23, 24). Our data confirm the instability of the chromosome number in Cytisus . The presence of B chromosomes in C. valdesii and C. megalanthus , as well in other species, is discussed in relation to this instability and previous data. We suggest that instability of the chromosome number within a taxon, and even in the same population, may be related to the breakage of A chromosomes and the appearance of B chromosomes.

Assessment of heavy metals accumulation by spontaneous vegetation: Screening for new accumulator plant species grown in Kettara mine-Marrakech,Southern Morocco

The present paper aims to perform a screening of native plants growing in Kettara mine-Marrakech (Southern Morocco) for its phytoremediation. Plants and soil samples were collected and analyzed for Pb, Zn, Cu and Cd concentrations at several sites in the mine. The results showed that the soil in the vicinity of Kettara mine is deficient in major elements and contain toxic levels of metals. Spontaneously growing native plants were botanically identified and then classified into 21 species and 14 families. Significant difference was observed among the average concentrations of four heavy metals (Pb, Zn, Cu and Cd) in plants (p ≤ 0.05). Six plants of 21 species namely Hammada scoparia (Pomel) Iljin, Hirschfeldia incana (L.) Lagreze-Fossat, Lamarckia aurea (L.) Moench, Calendula algeriensis Boiss. & Reuter, Aizoon hispanicum L. and Melilotus sulcata Desf. were considered as the best-performing specimens due to their high ability to accumulate multiple metals in their shoots and roots without sustaining toxicity. This was confirmed by the transfer factors generally higher than 1. Using the most common criteria to classify the hyperaccumulator plants, these species can be classified as new accumulator plants of many heavy metals and be potentially used as remediation tools of metal-contaminated sites.

Essential oils from two endemic species of Apiaceae from Iran

The composition of essential oils of Leutea glaucopruinosa (Rech.f.) Akhani & Salimian comb. nov., and Zeravschania (Boiss. & Hausskn.) Salimian & Akhani comb. nov. were analysed by GC-MS. 49 compounds are identified in the former and 33 compounds in the latter, comprising a total of 76 compounds in both species. Both species were originally described under Peucedanum, which are transferred in this paper into Leutea and Zeravschania, respectively. The chemical compounds of the essential oils show that there are only seven common compounds between two species. The major compounds of L. glaucopruinosa are mostly monoterpene hydrocarbons and oxygenated monoterpenes, in which alpha-pinene (31.5%), sabinene (9.7%), beta-pinene (9.2%), exo-fenchyl acetate (4.5%) are dominant. In Z. pastinacifolia sesquiterpene hydrocarbons and phenylpropanoids dominate with beta-bisabolene (37.3%), 3,1-butyl-1,2-dimethoxy benzene (14.9%), 10,11-dimethylbicyclo[6.3.0]undec-(8)-en-9-one (12.9%), 4-t-butyl-1,2-dimethoxy benzene (6.8%), (E)-asarone (5.1%) and elemicine (4.1%) as major compounds.

Among them, twelve species (Coleophora lativalva sp. nov., C. ossaedeaga sp. nov., C. pendulivalvula sp. nov., C. novisqualorella sp. nov., C. capitargentella sp. nov., C. curvidentatella sp. nov., C. dorsiproducta sp. nov., C. harbinensis sp. nov., C. xinjiangensis sp. nov…C. cuprea sp. nov., C. pallidiptera sp. nov. and C. resupina sp. nov.) are described as new to science and fifteen species are newly recorded from China. Carpochena halostachyos Falkovitsh is proposed as a synonym of Coleophora plicipunctella Chrètien. Genitalia of new species are illustrated and females of Coleophora armeniae Baldizzone et Patzak, C. carchara Falkovitsh and C. sequens Falkovitsh are described for the first time. A key to Chinese species of Coleophora salicorniae group is given.     

Morphological diversity and structure of West Mediterranean Abies species

The aim of this study was the biometrical comparison of Abies pinsapo Boiss., Abies maroccana Trab. and Abies tazaotana Côzar ex Villar from Spain and Morocco. The morphological and anatomical analysis of the needle characters of these firs revealed significant taxonomic differences. The results showed considerable distances between regions and very small differences among the Moroccan fir taxa. The examination of the needles and earlier genetic analysis did not provide evidence for distinguishing A. tazaotana at the species level.     

Centaurea amanosensis (Asteraceae), a new species from Turkey

Centaurea amanosensis M. Bona, a new species of Asteraceae from Hatay province of Turkey is described and illustrated. It is morphologically similar to C. cheirolopha (Fenzl) Wagenitz, C. lycopifolia Boiss. & Kotschy ex Boiss. & Kotschy, and C. stevenii Bieb. (Section Pseudoseridia), but it differs mainly in life form, general habit, leaves and achene characters. The IUCN conservation status of Critically Endangered (CR) should be applied to C. amanosensis.
