Melilotus comprises 19 species, while the phylogenetic relationships between species remain unclear. In the present work, three chloroplast genes, rbcL, matK, trnL-F, and one nuclear region, ITS (internal transcribed spacer) belonging to 48 populations of 18 species of Melilotus were sequenced and phylogenetic trees were constructed to study their interspecific relationships. Based on the phylo...

We describe and illustrate Croton restingae Sodré & Riina sp. nov., a new species endemic to restricted area in the state of Rio de Janeiro, Brazil, characterized by particular type vegetation Atlantic Forest known as restinga. The belongs sect. Adenophylli subsect. Laceratoglandulosus, which is supported morphology phylogenetic analysis based on nrDNA ITS sequence data. most closely relate...

Three monophyletic branches are strongly supported in a phylogenetic analysis of the Teloschistaceae based on combined data sets of internal transcribed spacer and large subunit nrDNA and 12S small subunit mtDNA sequences. These are described as new monotypic genera: Jasonhuria S. Y. Kondr., L. Lőkös et S. -O. Oh, Loekoesia S. Y. Kondr., S. -O. Oh et J. -S. Hur and Olegblumia S. Y. Kondr., L. L...

Recent discovery of a low shrub from Topia, in the state of Durango, Mexico that appears similar to both J. durangensis and J. jaliscana, prompted the analyses of nrDNA and petN-psbM (cpDNA) SNPs. The plants from Topia differed from J. durangensis by 2 indels but were shown to be closely related as shown in a minimum spanning network. Phytologia 91(2): 353-358 (August, 2009).

Recent nrDNA and trnC-trnD sequence data revealed that J. monticola and J. m. f. compacta are not monophyletic, and this prompted additional research using Single Nucleotide Polymorphisms (SNPs). The SNPs data clearly show that J. monticola f. compacta is not conspecific with J. monticola f. monticola. Juniperus monticola f. compacta Mart. is raised to the specific level as: Juniperus compacta ...
