  Factsheet - Dipsacaceae
The Dipsacaceae also have either 2 or 4 stamens; the number of stamens in Compositae is rarely reduced to 4.
Stamens in the Calyceraceae are alternating with the corolla lobes whereas they are epipetalous in the Dipsacaceae.
Although both the Dipsacaceae and Calyceraceae have persistent calyces those in the Calyceraceae typically become lignified and spiny; those in the Dipsacaceae become cupuliform or divided into a number of setae.

scabiosae, anther smuts on the genus Knautia (Dipsacaceae).
Given the monophyly of this group, the most parsimonious interpretation is the paraphyly of the smut fungi on Dipsacaceae with respect to the parasites of the other two families.
In contrast, only 11 (4.4-3.6%) out of the 250–300 species of Dipsacaceae are known to be parasitised by anther smuts [6,39].

 Implications of molecular characters for the phylogeny of the Microbotryaceae (Basidiomycota: Urediniomycetes)
Polyphyly of Dipsacaceae parasites does not receive support in our analyses, however, the sister-group relationship of M. intermedium on Scabiosa and parasites of Lentibulariaceae and Lamiaceae is well supported.
Given the monophyly of this group, the most parsimonious interpretation is the paraphyly of the smut fungi on Dipsacaceae with respect to the parasites of the other two families.
Based on a larger dataset as in previous studies, we could confirm the monophyly of the caryophyllaceous anther smuts and that there exists a group of North American anther smuts on native hosts that is clearly separated from the European clade.

 Secret Seeds Scabiosa
Family: Dipsacaceae (Hardy perennial) Parent of many garden hybrids, this scabious is every bit as pretty with nodding flat heads of dusky mauve in summer. 2m (6-7ft) Sun or part shade / well drained. (30+ seeds)
Family: Dipsacaceae (Hardy perennial) Collected from waste ground near Benidorm, this plant has lots of beautiful pale pink/mauve flowers during summer. This one was flowering in December. 60-90cm (2-3ft) Sun / loam. (20+ seeds)
Family: Dipsacaceae (Hardy annual) A vast array of pastel pinks and whites in this selection of stunning annuals. As the name suggests the colours are reminiscent of strawberry and vanilla ice cream. 30-60cm (1-2ft) Sun / loam. (20+ seeds)

 Dipsacales
This study demonstrates the wide range of divergence times that can be obtained using different methods and data sets, and cautions against reliance on age estimates based on only a single gene or methodology.
For Dipsacaceae, Caputo and Cozzolino (1994) analyzed morphological characters, Mayer and Ehrendorfer (1999, 2000) presented phylogenetic hypothesis for Scabiosa and Pterocephalus and their relatives, and studies are underway using trnL, matK, ITS (Bell and Donoghue, unpublished data) In all, nearly 300 species have now been included in one or another phylogenetic analysis.
To date the single most convincing phylogenetic study of the Dipsacales, both in terms of character number (7593 nucleotide sites) and confident resolution, is that of Bell et al.

 Botany & Plant Biology 2007 - Abstract Search
The Mediterranean-centered Dipsacaceae (Dipsacales) is characterized by an epicalyx, a novel structure that subtends the flower and forms the dispersal apparatus.
Different epicalyx phenotypes are responsible for the many dispersal syndromes found in the group, which suggests that the epicalyx is a “key innovation” that spurred the adaptive radiation of the Dipsacaceae.
Phylogenetic relationships within Dipsacaceae were inferred using sequence data from two chloroplast regions (the trnL intron and the trnS-G intergenic spacer) and the internal transcribed spacer (ITS) region of nuclear ribosomal DNA.

Phylogenetic relationships among 17 taxa of Dipsacaceae were inferred from nucleotide sequence variation in both the internal transcribed spacer (ITS) regions of nuclear ribosomal DNA and the chloroplast trnL
Our phylogenetic hypothesis indicates that adaptations to seed dispersal have been a very strong driving force in Dipsacaceae evolution, with similar selective pressures causing the onset of similar epicalyx shapes and dispersal modes in a parallel fashion in various taxa.
For this reason, the gross morphology of the involucel is deceptive in inferring relationships.

 Yale Peabody Museum: Botany: Current Research: Phylogeography in the Cretan Area
The Dipsacaceae is a family comprising 5 genera (Cephalaria, Lomelosia, Knautia, Pterocephalus and Sixalis) and 11 species.
These plants grow on calcareous rocks, cliffs, and abandoned terraces often on rocky phrygana, and their elevational distribution ranges from 0 to1,800 meters (0 to 5,906 feet).
Therefore, it is possible that elements in the Campanulaceae, Dipsacaceae and Valerianaceae could represent palaeorelicts of the continent having differentiated before the splitting up of the Aegean landmass, which have since been conserved in restricted habitats.

 Pyck, Nancy* and Erik Smets.   (Site not responding. Last check: )
The order Dipsacales is classified in Euasterids II and comprises six families following APG: Caprifoliaceae, Diervillaceae, Linnaeaceae, Dipsacaceae, Valerianaceae and Morinaceae.
In classifications of Dipsacales the genus Triplostegia is treated as a member of Valerianaceae, Dipsacaceae, or even as a monogeneric family.
The results presented, indicate that the position of Triplostegia remains equivocal: molecular data suggest a basal position in Dipsacaceae, while the morphological matrix and the total combined data set show Triplostegia as sister to all Valerianaceae.

Identification: Flowers lavender, pink to blue with 4 petals, small and arranged in an egg-shaped flowering head.
Cut-leaf Teasel (Dipsacus laciniatus) (not treated here) is very similar to Fuller's Teasel, but the leaves are lobed, particularly toward their fused bases.

To this end, I integrate knowledge from field studies (demographic surveys), greenhouse experiments (inbreeding depression experiments), and modeling (matrix population models).
Some of the plant species I have worked with are Lobularia maritima (Brassicaceae), Hypericum cumulicola (Hypericaceae), Ramonda myconi (Gesneriaceae), Scabiosa columbaria (Dipsacaceae), Tragopogon pratensis (Compositae), Hypochaeris radicata (Compositae), and Succisa pratensis (Dipsacaceae).
In addition, I am also interested in the evolution of floral morphology from both ecological and molecular points of view.
