TLDR
Theligonaceae zeigen einige Merkmale (unitegmische, tenuinuzellate Samenanlage) die sehr h~ufig vorkommen in Familien, welche iridoide Glycoside enthalten wurde mittels Bestimmung der Schmelzpunkte and der spezifischen optischen Rotat ionen erh~rtet. Expand
Phylogeny and classification of the subfamily Rubioideae (Rubiaceae)
TLDR
P phylogenetic analyses of the subfamily Rubioideae (Rubiaceae) based on three different pieces of chloroplast DNA, the protein coding rbcL gene, the spacer sequence betweenatpB andrbcL, and the recently published rps16 intron data are performed. Expand

  • 2004
TLDR
Comparisons with other Rubiaceae (especially Pavetteae), show that hemianatropy and campylotropy occur more often in theRubiaceae than hitherto accepted and corroborates the close affinity between Rutidea andNichallea. Expand

AbstractThe orderCaryophyllales (Centrospermae) was found to contain specific P-type sieve-element plastids which are characterized by protein inclusions composed of ring-shaped bundles of filamentsExpand
Theligonum cynocrambe: Developmental morphology of a peculiar rubiaceous herb
The annual Mediterranean herbTheligonum cynocrambe shows a peculiar combination of morphological characters, e.g., switch from decussate to spiral phyllotaxis with 90–100° divergence, combined with aExpand
A consensus classification for the order Gentianales with additional details on the suborder Apocynineae
TLDR
The Gentianales as circumscribed by Benson, Cronquist, Dahlgren, Goldberg, Hey wood and al., Melchior, Stebbins, Takhtajan and Thorne is investigated and a consensus classification or classificatory model for the order is proposed. Expand
Phylogenetic utility of the nuclear rDNA ITS region in subfamilyIxoroideae (Rubiaceae): Comparisons with cpDNArbcL sequence data
TLDR
ITS of the nrDNA were sequenced for 21 taxa inIxoroideae and outgroups (Rubiaceae) and compared with sequences of the cp-generbcL and inconsistencies found may be caused by density of taxon sampling, different evolutionary rates, phylogenetic sorting, homoplasy caused by functional constraints, or sampling of non-orthologous ITS types. Expand
Systematics, taxonomy and floristics of Brazilian Rubiaceae: an overview about the current status and future challenges
TLDR
The present work is to offer an overall view of the most recent family classification with emphasis on the genera of Rubiaceae occurring in Brazil, and to indicate particular taxa that are still in need of phylogenetic and taxonomic studies. Expand

Remarks on the position, the delimitation and the subdivision of the Rubiaceae
TLDR
Some of the characters by the aid of which in the Rubiaceae very suitable keys to the genera have been constructed, but which when they were used for the elaboration of a classification, led to entirely unsatisfactory results are discussed. Expand
