“…Within the Genista ephedroides complex, both the restriction fragment analysis and the investigation of De Castro et al (2002) allowed to distinguished some units. A plesiomorphic unit includes the only two contintental taxa, G. numidica and G. cilentina, which are considered the most ancient species; G. numidica (an Algerian endemic) would be close to the hypothetical ancestor of the group, as previously emphasized also by Estabrook (2001).…”

“…Spartocarpus, on the basis of the sequencing of ITS1 and ITS2 of ribosomal DNA and of the chloroplast DNA trnL gene, by De Castro et al (2002), who recognized three units, besides one in Balearic Islands (Ibiza) with Genista dorycnifolia. The first is represented by G. numidica and G. cilentina, regarded as ancient species; the second includes the southern Tyrrhenian species (G. demarcoi, G. gasparrinii, G. tyrrhena); the third comprehends the Sardinian species (of which only G. ephedroides and a population of G. valsecchiae s.l., likely to be attributed to G. bocchierii, were analysed); the last two units are considered more recent.…”

Analysis of the Genista ephedroides group (Fabaceae) based on karyological, molecular and morphological data

et al. 2012

Within the genus Genista, the species belonging to the G. ephedroides complex are examined from karyological, molecular and phenetic point of view. All the examined taxa show a chromosome complement with 2n = 48, occasionally with some accessory chromosomes. In addition, the aneuploid number 2n = 44 was found only in G. ovina, while higher counts (2n = 72 and 2n = 96) are reported for G. tyrrhena ssp. pontiana. As concerns the DNA, the restriction fragment analysis of the ribosomal ITS1 (HaeIII, RsaI) and 5.8S-ITS2 (HaeIII) regions was used; the classification and ordination of the taxa allow to distinguish three clusters: the first including the S-Tyrrhenian taxa, the second all the Sardinian and Balearic taxa, and the third grouping G. numidica and G. cilentina. The phenetic analysis was performed by using 40 morphological characters processed by the NTSYSpc package. The relative cladogram distinguishes three main clades: the most isolated including the Sicilian species, the other two separating the Sardinian and Balearic species from the STyrrhenian and Algerian ones.
