  author={Massimo Bigazzi and Enio Nardi and Federico Selvi},
  journal={Plant Systematics and Evolution},
The two closely related speciesLycopsis variegata andAnchusa cretica, formerly placed inAnchusa subg.Rivinia, were compared with the type species ofLycopsis andAnchusa, on the basis of a set of macro and microcharacters. The presence of only two fertile stamens as well as other peculiar characters in flower structure, androecium, gynoecium, pollen and fruit, supports the institution of the new genusAnchusella, consisting ofA. variegata andA. cretica. Karyological and eco-chorological aspects… 

Revision of genus Anchusa (Boraginaceae-Boragineae) in Greece

A new species A. leucantha, endemic to a small area with ophiolitic outcrops in West Macedonia, is described and previously considered a Greek endemic, is shown to be a heterotypic synonym of A. sartorii.

A Morphological and Anatomical Study on Anchusa leptophylla Roemer & Schultes (Boraginaceae) Distributed in the Black Sea Region of Turkey

The morphological and anatomical characteristics of Anchusa leptophylla and A. incana, which are distributed in the Black Sea region, were investigated and features related to characteristics of the leaf and calyx were found to be important in separating the subtaxa morphologically.

Synopsis of Boraginaceae subfam. Boraginoideae tribe Boragineae in Italy

A synopsis of the Italian taxa of tribe Boragineae (Boraginaceae, subfam. Boraginoideae) is given, including analytical keys, hybrids, list of synonyms and short distribution notes, together with the lists of the selected specimens upon which they are based.

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.

Micromorphology of glandular structures in Echium vulgare L. flowers

The micromorphology of selected elements of Echium vulgare L. flowers was investigated, with special attention to the structure of the nectaries and the stigma of the pistil as well as types of

Variation in nectar-sugar profile of Anchusa and allied genera (Boraginaceae).

Dry habitats and time of flowering are the main determinants of nectar–sugar composition in the genus Anchusa sensu lato, and small differences in sugar profiles do not reflect phylogenetic relationships based on molecular studies.

Notes on the genus Echinops L. (Asteraceae) in SE Europe

ABSTRACT The occurrence of Echinops siculus Strobl, previously considered endemic to Italy, is for the first time reported from the Balkan Peninsula based on plants collected in Corfu (Greece).



The ultimate types ofAnchusa L. and Lycopsis L. (Boraginaceae)

The tribe Boragineae Bercht was regarded by Johnston (1924) as a natural group of the Boraginaceae, consisting of closely related genera showing reticulate variation of several significant characters, but one of the taxonomic problems concerns the delimitation of two Linnaean genera, Anchusa and Lycopsis.

A general survey of pollen types in Anchusa L. (Boraginaceae) in relation to taxonomy

Sometimes, the pollen types correspond well with the genera segregated from Anchusa and pollen morphology is discussed in relation to the complex taxonomy of the group.

Giemsa Banding and Karyotype in three Species of Anchusa (Boraginaceae)

All the species of Anchusa examined have shown a distinctive C-band pattern detectable by the Giemsa technique, with evident intraspecific polymorphism in A. banelieri and A. italica.

Stigma characteristics and angiosperm taxonomy

When a classification based upon certain morphological and physiological characters of the stigma was applied to ca. 1,000 species of some 900 genera of angiosperms, several taxonomic regularities

Cytology of Anchusa and Its Relation to the Taxonomy of the Genus

Anchusa italica and its varieties are shown to be allotetraploids and Johnston's combining the sections Buglossum and Euanchusa is in agreement with their cytological similarity.

Cytotaxonomic Investigations in Some Angiosperms Collected in the Valley of Aosta and in Tre National Park « Gran Paradiso »

SUMMARYThe chromosome number of 53 species of Angiosperms, occurring in the Valley of Aosta and in the National Park « Gran Paradiso » was determined. Some notes on the taxonomy of some species are

The receptive surface of the angiosperm stigma

The physiological importance of stigma type is shown by the correlations that exist between the characteristics of the receptive surface and self-incompatibility system, and various taxonotnic regularities emerge.

Morphology of flowers and inflorescences
