    Notes: Abstract Random Amplified Polymorphic DNA (RAPD) was used to generate molecular markers to trace the origin of the fodder legume tagasaste (Chamaecytisus proliferus (L. fil.) Link ssp. palmensis (H. Christ) Kunkel) in the Canary Islands. Results from multivariate analyses of data through “Two Way Indicator Species Analysis” (TWINSPAN) and “Detrended Correspondence Analysis” (DECORANA) showed that genotypes collected on the island of La Palma exhibited a wider range of variation than those from the other islands. This supports the existing hypothesis that tagasaste originated on La Palma and emphasizes the importance of conserving and evaluating germ plasm from this island.

    Reproductive characters associated with breeding behaviour inBeta sect.Beta (Chenopodiaceae) (1983)
    Springer
    Plant systematics and evolution 143 (1983), S. 277-283

    ISSN: 1615-6110
    Keywords: Angiosperms ; Chenopodiaceae ; Beta ; Reproductive biology ; allogamy versus autogamy

    Topics: Biology
    Notes: Abstract Populations of different taxa withinBeta sect.Beta were compared using a number of floral and reproductive characters. Plants which were known to be self-incompatible (through S-allele incompatibility) were found to be morphologically distinct from those which were self-compatible, with the floral characteristics of the latter promoting their autogamy.

    The phytogeography of the Chamaecytisus proliferus (L. fil.) Link (Fabaceae: Genisteae) complex in the Canary Islands: a multivariate analysis (1994)

    Notes: Abstract Chamaecytisus proliferus (L.fil.) Link (Fabaceae: Genisteae) represents a species complex in the Canary Islands. Floristic data from 147 releves from the whole complex were collected and analysed by classification (TWINSPAN) and ordination (DECORANA) methods. Results indicate that white escobon of Tenerife, escobon of El Hierro, white escobon of Gran Canaria and typical tagasaste in La Palma are associated with those plant communities from the north of these islands which are under the influence of the north-eastern trade winds. Narrow-leaved escobon in Tenerife and La Gomera, escobon of southern Gran Canaria and white tagasaste of La Palma are found in those areas which are not under the direct influence of these winds. Morphological forms from the more easterly islands (Gran Canaria and Tenerife-La Gomera) have the broadest ecological range and they have played an important role in the floristic changes which have taken place after the destruction of the forests in these islands. The highest priorities for in situ conservation should be given to wild populations of typical tagasaste, white escobon of Tenerife and escobon of El Hierro.

    The evolutionary significance of multigermicity in the genusSpinacia (Chenopodiaceae) (1981)

    Notes: Abstract The presence of multigerm seedballs in the chenopodiacious genusSpinacia is noted. In the wild, colonising, and “weedy” dioecious species,S. turkestanica andS. tetrandra, the distribution of a multigerm seedball could effectively overcome the problem posed by isolation of the sexes. The hypothesis is tested assessing the extent of intra-seedball progeny hybridisations and seed production in the two wild species. The success in seed production by intra-seedball progeny crosses suggests that the distribution of such seedball progeny groups permits not only a percentage survival under isolation of these dioecious plants, but also the colonisation of areas outside that of the parent populations.
