Molecular phylogenetic evidence for the geographic origin and classification of Canary Island Lotus (Fabaceae: Loteae).
Molecular phylogenetic analyses of Macaronesian Lotus and related genera were conducted to assess their biogeographic history and taxonomy. Macaronesian Lotus, which are typically classified within one of two subgenera, Lotus subgenus Pedrosia or L. subg. Rhyncholotus, are diagnosed by the presence of a forked or toothed style and differences in corolla morphology. Maximum parsimony and Bayesia...
متن کاملTribal delimitation and phylogenetic relationships of Loteae and Coronilleae (Faboideae: Fabaceae) with special reference to Lotus: evidence from nuclear ribosomal ITS sequences.
The temperate herbaceous tribes Loteae and Coronilleae have traditionally been regarded as taxonomically distinct entities. More recent morphological assessments, however, have challenged this view and suggest combining the two tribes under Loteae. Two key features used to distinguish the Coronilleae from Loteae include jointed fruits and branched root nodules. We evaluate the taxonomic utility...
متن کاملTwo new species and a new record of the genus Astragalus (Fabaceae) from NE Iran
During the study on the specimens of Astragalus sect. Ammodendron in the herbarium of Ferdowsi University of Mashhad (FUMH), based on the last and most recent sources, two new species, i.e. A. microfoliolatus sp. nova and A. rashed-mohasseli sp. nova were found and described. Morphological evidence confirmed that the belonging of these taxa to Astragalus sect. Ammodendron. The most important di...
متن کاملPhytochemical and Biological Studies on the Different Organs of Tanacetum parthenium L. Cultivated in Egypt
Phytochemical investigation of Tanacetum parthenium L. family Asteraceae cultivated in Egypt resulted in isolation and identification of four flavonoids. One surface flavonoid was isolated from the fresh leaves and three other flavonoids were isolated from the flower heads. Four sesquiterpene lactones were isolated from the leaves. Two sterols were isolated from the roots. A comparative study o...
متن کاملChromosome studies in the genus Jatropha L
The inflorescences of ten species of the genus Jatropha were fixed in Cornoy’s fluid (6:3:1). Acetocarmine stain (2%) was used for staining the pollen mother cells. Seven species exhibited 11 bivalents and 2n =22 and x=11. But the two other species, J.villosa var. villosa and J.villosa var. ramnadensis showed only 10 bivalents and 2n number of 20 chromosomes and x=10. The study concluded the oc...
