    Springer
    Plant systematics and evolution 130 (1978), S. 203-207 
    Details
    ISSN: 1615-6110
    Keywords: Angiosperms ; Caryophyllaceae ; Silene ; Chromosome numbers ; Flora of Greece ; Crete
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The chromosome numbers of several Greece species of the genusSilene L. from natural habitats are reported for the first time:S. sieberi, S. niederi, S. radicosa subsp.rechingeri, S. oligantha, S. skorpilii, S. schwarzenbergeri andS. fruticulosa. All species are diploid with 2n = 24 chromosomes, including 0, 2 or 4 SAT-chromosomes;S. niederi has B-chromosomes.

    Variation on the population, racial, and species level in the primitive relic Angiosperm genusDrimys (Winteraceae) in South America (1979)
    Springer
    Plant systematics and evolution 132 (1979), S. 53-83 
    Details
    ISSN: 1615-6110
    Keywords: Angiosperms ; Winteraceae ; Drimys s. str. ; D. brasiliensis (with subsp. and comb. nov.) ; D. roraimensis ; comb. nov. ; D. angustifolia ; Population variation ; eco-geographical differentiation ; epidermis ultrastructure ; Systematics and history of the S. American flora
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Statistical analyses and scatter diagrams illustrate for the polymorphic E. and SE. BrazilianDrimys brasiliensis a clear correlation between morphological variation and eco-geographical differentiation. This is backed by data on the (ultra)structure of the lower leaf surface. A new infraspecific taxonomy is proposed, andD. roraimensis andD. angustifolia are recognized as distinct species of the Guyana Highlands and S. Brazil, respectively. The affinities between these and other taxa of the paleopolyploid genus, its evolution and its position within the family are discussed.

    Chromosomenzahlen einiger mediterraner und mitteleuropäischerCentaurea-Arten (Asteraceae) (1975)
    Springer
    Plant systematics and evolution 123 (1975), S. 107-115 
    Details
    ISSN: 1615-6110
    Keywords: Angiosperms ; Asteraceae ; Centaurea ; Chromosome numbers ; Flora of the Mediterranean and C. Europe
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The chromosome numbers of several Mediterranean and Central European species from the genusCentaurea L. have been studied. The material was collected in natural habitats, exceptC. thracica andC. maxima. The numbers forC. cineraria (2n = 36; tetraploid!),C. subtilis (2n = 22),C. sonchifolia (2n = 44),C. sphaerocephala (2n = 44),C. napifolia (2n = 22),C. achaia (2n = 22),C. thracica (2n = 18), andC. maxima (2n = 28) are reported for the first time. For the following species earlier counts are confirmed:C. cineraria (diploid, 2n = 18),C. maculosa (2n = 18),C. rhenana (2n = 18),C. triumfettii (2n = 22 + 0−1 B; first report of accessory chromosome for this species),C. scabiosa (2n = 20 + 0−3 B),C. crassifolia (2n = 30). B-chromosomes are reported for 3 populations ofCentaurea scabiosa from Berlin; they lack in 2 populations from Bayern and Hessen.
