Stigma form and surface in the tribe Boragineae (Boraginaceae): micromorphological diversity, relationships with pollen, and systematic relevance
A comparative analysis of stigma form in 62 species representing 15 genera of the tribe Boragineae by means of light and electron microscopy highlighted the structural diversity, peculiarity, and functional specialization of the receptive surface of the boraginaceous stigma.
Pollen morphology in theBoragineae (Boraginaceae) in relation to the taxonomy of the tribe
Palynological data do not support a broad concept of the genus Anchusa, and point to the autonomy of the ‘satellite’ generaHormuzakia, Gastrocotyle, Phyllocara, Pentaglottis andCynoglottis.
Molecular systematics of Boraginaceae tribe Boragineae based on ITS1 and trnL sequences, with special reference to Anchusa s.l.
Molecular data show that nine of the usually accepted genera of the Boragineae consisting of two or more species are monophyletic: Anchusella, Borago, Brunnera, Cynoglottis, Gastrocotyle, Hormuzakia, Nonea, Pulmonaria and Symphytum, and the tribe includes the four monotypic genera Paraskevia, Pentaglott is, Phyllocara and Trachystemon.
Anchusa L. and allied genera (Boraginaceae) in Italy
ABSTRACT A revision of the Italian entities of Anchusa and of the related genera Anchusella, Lycopsis, Cynoglottis, Hormuzakia and Pentaglottis was carried out in view of the poor systematic…
Leaf surface and anatomy in Boraginaceae tribe Boragineae with respect to ecology and taxonomy
Molecular phylogeny, morphology and taxonomic re‐circumscription of the generic complex Nonea/Elizaldia/Pulmonaria/Paraskevia (Boraginaceae‐Boragineae)
A molecular phylogenetic analysis of the generic complex Nonea/Elizaldia/Paraskevia/ Pulmonaria (Boraginaceae-Boragineae) using trn L UAA and ITS1 sequences from non-coding plastid and nuclear DNA suggests a rede-finition of Nonea s.l. based on monophyletic groups.
Karyotype variation, evolution and phylogeny in Borago (Boraginaceae), with emphasis on subgenus Buglossites in the Corso-Sardinian system.
Molecular data support the monophyly of Borago, while relationships in subgenus Borago remain unclear, and high ITS1 variation in the tetra- and hypotetraploid races of B. pygmaea suggests a multiple origin.
CHROMOSOME STUDIES IN TURKISH SPECIES OF NONEA ( BORAGINACEAE ): THE ROLE OF POLYPLOIDY AND DESCENDING DYSPLOIDY IN THE EVOLUTION OF THE GENUS
Ultrastructure of vegetative and motile cells, and zoosporogenesis in Chrysonephos lewisii (Taylor) Taylor (Sarcinochrysidales, Pelagophyceae) in relation to taxonomy
Ultrastructural observations on the vegetative filaments, motile cells and processes leading to zoospore differentiation in Chrysonephos lewisii are presented. Vegetative filaments are embedded in a…

Under most conditions with dendrimers present, the d endrimers, rather than the liposomes, are visible in the TEM images, demonstrating that the UO22+ is complexed to the dendedrimers and not to the Liposomes.
