Congruence of a phylogeny of Cordiaceae (Boraginales) inferred from ITS1 sequence data with morphology, ecology, and biogeography.
The phylogenetic relationships of Cordiaceae were investigated using ITS1 sequences from 50 ingroup taxa and three outgroup taxa. Molecular analyses suggest that Coldenia procumbens, traditionally… Expand

Multiple origins for Hound's tongues (Cynoglossum L.) and Navel seeds (Omphalodes Mill.)--the phylogeny of the borage family (Boraginaceae s.str.).
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.… Expand
