Island colonization and evolution of the insular woody habit in Echium L. (Boraginaceae).
It is argued that the origin of insular woodiness involved response to counter-selection of inbreeding depression in founding island colonies, and was furthermore accompanied by intense speciation, which brought forth remarkable diversity of forms among contemporary island endemics.
Secondary Structure of the ITS1 Transcript and its Application in a Reconstruction of the Phylogeny of Boraginales
A general secondary structure of ITS1 for Boraginales, with four major helices, is proposed here and it is demonstrated that in each subtaxon, derivations from this structure are found.
Congruence of a phylogeny of Cordiaceae (Boraginales) inferred from ITS1 sequence data with morphology, ecology, and biogeography.
A set of ancestral characters (including apomorphies and plesiomorphies) is reconstructed for Cordiaceae based on lie phylogenetic hypotheses as inferred from the congruence between morphological and ITSI data.
Phylogeny and systematics of Lithodora (Boraginaceae-Lithospermeae) and its affinities to the monotypic genera Mairetis, Halacsya and Paramoltkia based on ITS1 and trnLUAA-sequence data and morphology
A critical reevaluation of carpological characters traditionally used to delimit Lithodora corroborates the results of the molecular analysis and indicates that the cupulate areole and the mericarpid appendage found in the genus are homoplasious.
The borage family (Boraginaceae s.str.): A revised infrafamilial classification based on new phylogenetic evidence, with emphasis on the placement of some enigmatic genera

Multiple origins for Hound's tongues (Cynoglossum L.) and Navel seeds (Omphalodes Mill.)--the phylogeny of the borage family (Boraginaceae s.str.).
The phylogeny shows high statistical support for most nodes on the backbone and on the individual clades, and suggests that the family originated in Africa and western Asia and radiated to eastern Eurasia, with several independent dispersal events into Australia and the New World.
Diversification in the Andes: age and origins of South American Heliotropium lineages (Heliotropiaceae, Boraginales).
The hypothesis that the Andean South American groups of Heliotropium originated and diversified in response to Andean orogeny during the late Miocene and a the subsequent development of aridity is examined.
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.
Fossil and Extant Western Hemisphere Boragineae, and the Polyphyly of “Trigonotideae” Riedl (Boraginaceae: Boraginoideae)
Molecular data show that “Trigonotideae” are polyphyletic, and none of its members is at all closely related to Trigonotis itself, and several fossil taxa from the Cenozoic of North America can be confidently placed into Boragineae.
