1.	Olsson, Åsa, et al. (author) Relationships between Nordic dogroses (Rosa L. sect. Caninae, Rosaceae) assessed by RAPDs and elliptic Fourier analysis of leaflet shape 2000 In: Systematic Botany. - 0363-6445. ; 25:3, s. 511-521 Journal article (peer-reviewed)abstract The taxonomy of the dogroses (Rosa sect. Caninae) is notoriously problematic and all the members of the section are characterized by a form of unbalanced meiosis (so-called "canina meiosis"). We used a novel combination of random amplified polymorphic DNA (RAPD) markers and elliptic Fourier analysis of leaflet shape to investigate relationships within and between the seven common dogrose tara in the Nordic countries. A between-individual genetic distance matrix calculated on the basis of the presence/absence of RAPD hands was used in a non-metric multidimensional scaling analysis. Population data from elliptic Fourier analysis of leaflet shape were analyzed with canonical variates analysis. Elliptic Fourier analysis of leaflet shape provided a valuable complement to traditional, often subjectively-assessed, morphological characters and detected subtle patterns of within- and between-taxon differentiation that are generally consistent with the relationships recognized in the current taxonomic treatments of the section. In contrast, RAPDs emphasize the discontinuities between three groups of taxa and suggest that R. canina and the two subspecies of X. dumalis, as well as the taxon-pair A, sherardii and X. villosa subsp. mollis, are more closely related than can be concluded on the basis of morphological characters.
2.	Lavin, M, et al. (author) Africa, the odd man out: Molecular biogeography of dalbergioid legumes (Fabaceae) suggests otherwise 2000 In: SYSTEMATIC BOTANY. - : AMER SOC PLANT TAXONOMISTS. - 0363-6445. ; 25:3, s. 449-467 Journal article (peer-reviewed)abstract Vicariant biogeographic relationships have been commonly sought, inferred, or assumed between Africa and South America. Yet for disjunct distributions involving North America and the Old World, Africa is rarely considered. We present a molecular biogeogra

(author) The enigmatic tribe whitfieldieae (Acanthaceae): Delimitation and phylogenetic relationships based on molecular and morphological data 2001 In: SYSTEMATIC BOTANY. - : AMER SOC PLANT TAXONOMISTS. - 0363-6445. ; 26:1, s. 104-119 Journal article (peer-reviewed)abstract Relationships of the enigmatic genera Whitfieldia, Chlamydacanthus, and Lankesteria (Acanthaceae) were examined using molecular sequence data for two chloroplast loci (ndhF gene, trnL-trnF spacer and intron) for these and a sample of taxa representing
4.	Thulin, M, et al. (author) Phylogeny and biogeography of the Ormocarpum group (Fabaceae): a new genus Zygocarpum from the horn of Africa region 2001 In: SYSTEMATIC BOTANY. - : AMER SOC PLANT TAXONOMISTS. - 0363-6445. ; 26:2, s. 299-317 Journal article (peer-reviewed)abstract The genus Zygocarpum is described with six species formerly of Ormocarpum. This genus is endemic to the Horn of Africa, the southern end of the Arabian Peninsula, and the island of Socotra. Analysis of combined nuclear ribosomal ITS/5.8S and morpholo
