The angiosperm family Boraginaceae includes ca. 1600 species distributed among ca. 110 genera. Some floral features are constant within the family, but many vegetative, floral, pollen, and nutlet traits vary. Utilizing 224 species of Boraginaceae and related taxa, five matrices were constructed with various combinations of morphological characters, three chloroplast DNA regions, and one nuclear...

Marcomeria viridiflora (Boraginaceae) is pollinated by broad-tailed and rufous hummingbirds in the White Mountains of Arizona. This is the first hummingbird-pollinated member of the family Boraginaceae to be recorded in western North America. It provides one more example of a predominantly beepollinated plant group that has given rise to one or a few exceptional species of hummingbird flowers i...

Asopines are predators of insects, with several species with potential as biocontrol agents of a number of pests. Metrogaleruca obscura (Degeer), a neotropical species of Galerucini, was introduced in Malaysia, Asia, and Mauritius, Africa, to control the spread of Cordia curassavica (Boraginaceae), a native plant of the neotropics. The occurrence of Podisus nigrispinus (Dallas) preying on M. ob...

Onosma anatolica Binzet, is described and illustrated as a new species from Niğde province in southern Anatolia, Turkey. It belongs to sect. Onosma L. subsect. Asterotricha (Boiss.) Gürke. The new species is closely related to Onosma subulifolia Riedl from which it is distinguished. Onosma anatolica is readily distinguished from Onosma subulifolia by its sterile shoots, the green-grey stem indu...

With its four species, Anchusa is one of the weedy genera of Boraginaceae in Iran. Its species are distributed in different habitats. In this study, the fruit morphological and micro-morphological features of the Anchusa taxa have been considered, so as to evaluate their diagnostic value. Eight qualitative and quantitative fruit features from 12 accessions of A. italica, A. strigosa, A. arvensi...

Externally accumulated flavonoid aglycones have been found for the first time in Nonea species. They exhibit only flavones, one of them being the rare tricetin-4'-methyl ether. Within the subfamily Boraginoideae, exudate flavonoids appear to be a rare character.

Recent studies all indicated that both the affinities and subdivision of Boraginaceae s.str. are unsatisfactorily resolved. Major open issues are the placement and affinities of Boraginaceae s.str. in Boraginales and the major clades of the family, with especially the large tribes Cynoglosseae and Eritrichieae repeatedly retrieved as non-monophyletic groups, and the doubtful monophyly of severa...

Dimorphism in style height has evolved repeatedly in flowering plants, with some individuals having short and others long styles; in the case of distylous species, stigma position varies reciprocally with that of the anthers. Distyly can be associated with divergence in the functional gender between long- and short-styled individuals, but gender divergence has rarely been investigated in specie...

One adenoma and one adenocarcinoma of the islet cells and one adenoma of the exocrine pancreas were found in 3 out of 15 rats given a single dose (500 to 1500 mg/kg body weight) of pyrrolizidine alkaloids from Amsinckia intermedia Fisch and Mey (Boraginaceae), tarweed, a plant known to cause livestock losses from liver damage in the United States. Among rats treated with Heliotropium supinum L....
