A new species of Cuscuta (Convolvulaceae: Cuscuteae) from South America is described, illustrated, and studied under light and scanning electron microscopy. Cuscuta taimensis is similar to Cuscuta racemosa, but differs in having oblong to elliptic calyx lobes and a circumscissile capsule. 
O genero Evolvulus L. (Convolvulaceae) na Regiao Sul do Brasil
Nine species of Evolvulus were found in southern Brazil, with three of them occurring in three states and six found only in Parana state, with an identifi cation key for species.
Disentangling Cuscuta identification in Brazil: a first taxonomic contribution to the northeast region species
The diversity of Cuscuta is studied for the northeast region of Brazil and eight species were recognized, occurring mainly in areas of Caatinga, that predominates in the region.
Micro-morphological study of Evolvulus spp. (Convolvulaceae): the old world medicinal plants
An identification key to species is constructed based on leaf anatomy and seed coat characters, which can be used in other subjects such as pharmaceutical botany, organic chemistry, taxonomy and horticulture, in terms of species identification.
Erratum to: Micro-morphological study of Evolvulus spp. (Convolvulaceae): the old world medicinal plants
There was an error in the Abstract section which was published with incorrect pollen size results, and this has now been updated in the original article.
Cuscuta L. (Convolvulaceae) na Região Sul do Brasil
RESUMO Cuscuta é amplamente distribuído e possui aproximadamente 200 espécies de parasitas volúveis. Estima-se que ocorram 26 espécies no Brasil, porém, não há estudos atuais publicados para a flora


A new species of Cuscuta (Convolvulaceae) from Michoacán, Mexico
A new species, Cuscuta cotijana, is described and illustrated from the Trans-Mexican Volcanic Belt in northwestern Michoacán, Mexico. The species is most closely related to Cuscuta jalapensis, C.
A phylogeny inferred from large ribosomal subunit (26S) rDNA sequences suggests that Cuscuta is a derived member of Convolvulaceae
Analysis of 26S rDNA sequences suggests that Cuscuta is a derived member of Convolvulaceae, which would place it within the Solanales or within the Polemoniales.
Systematics of Cuscuta chinensis species complex (subgenus Grammica, Convolvulaceae): evidence for long-distance dispersal and one new species
Cuscuta alata from Mexico, previously considered synonymous to C. chinensis and C. applanata, was found to be a distinct species based on both molecular and morphological evidence.
Pollen evolution and its taxonomic significance in Cuscuta (dodders, Convolvulaceae)
The morphology of pollen supports Cuscuta as a sister to either the “bifid-style” Convolvulaceae clade (Dicranostyloideae) or to one of the members of this clade.
Diversity and evolution of the gynoecium in Cuscuta (dodders, Convolvulaceae) in relation to their reproductive biology: two styles are better than one
Gynoecium features suggest that Cuscuta is allied with the “bifid clade” (Dicranostyloideae) in Convolvulaceae.
Classification of Convolvulaceae: A Phylogenetic Approach
A formal reclassification of Convolvulaceae reveals that many homoplasious characters were emphasized in previous classifications, resulting in formal recognition of non-monophyletic groups.
Evolutionary history and taxonomy of the Cuscuta umbellata complex (Convolvulaceae): Evidence of extensive hybridization from discordant nuclear and plastid phylogenies
The Cuscuta umbellata complex is one of the 15 major clades recently circumscribed in C. subg. Grammica. Most of its members occur in North America and the Caribbean (C. desmouliniana, C. lacerata,
Evolution and classification of flowering plants
My sincere thanks are extended to Prof. Dr. Kai Larsen of the University of Aarhus for offering me this opportunity to deal with Thai Cyperaceae, and to Dr. Tem Smitinand, Deputy Director-General of
Delimitation of major lineages within Cuscuta subgenus Grammica (Convolvulaceae) using plastid and nuclear DNA sequences.
The first phylogenetic study of Grammica using plastid trnL-F and nrITS sequences from a wide taxonomic sampling covering its morphological, physiological, and geographical diversity indicates that the fruit dehiscence character is homoplastic, thus compromising its value as a major taxonomic and evolutionary feature.
Monophyly of the Convolvulaceae and circumscription of their major lineages based on DNA sequences of multiple chloroplast loci.
The results indicate that Convolvulaceae are monophyletic and sister to Solanaceae and Humbertia is the sister to all other members of the family.
