Stigma form and surface in the tribe Boragineae (Boraginaceae): micromorphological diversity, relationships with pollen, and systematic relevance
TLDR
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. Expand
Molecular systematics of Boraginaceae tribe Boragineae based on ITS1 and trnL sequences, with special reference to Anchusa s.l.
TLDR
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 systematicExpand
Leaf surface and anatomy in Boraginaceae tribe Boragineae with respect to ecology and taxonomy
TLDR
No strict correlation occurred between surface elements, trichome structure, edaphic requirements and systematic position of the 14 examined taxa, although the presence of small amounts of sulphur and phosphorus in Nonea and a remarkable abundance of Potassium in nonea pulla and Pulmonaria picta could have systematic relevance.

Pollen morphology in theBoragineae (Boraginaceae) in relation to the taxonomy of the tribe
TLDR
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. Expand
Molecular phylogeny, morphology and taxonomic re‐circumscription of the generic complex Nonea/Elizaldia/Pulmonaria/Paraskevia (Boraginaceae‐Boragineae)
TLDR
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. Expand
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 aExpand
A TEM and EPR Investigation of the Competitive Binding of Uranyl Ions to Starburst Dendrimers and Liposomes: Potential Use of Dendrimers as Uranyl Ion Sponges
Transmission electron micrographs (TEM) of UO22+-negatively stained starburst dendrimers (SBDs), members of the family of dendritic macromolecules, have been analyzed in the absence and in theExpand
Karyotype variation, evolution and phylogeny in Borago (Boraginaceae), with emphasis on subgenus Buglossites in the Corso-Sardinian system.
TLDR
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. Expand
