Topic: Calyceraceae


  
  Asterales
Calyceraceae + Asteraceae: flowers small, C tubular, commissural veins connate, (median veins 0), filament collar +, G [2], with 1 ovule; fruit a cypsela, K persistent, modified, involved in dispersal.
Calyceraceae are herbs that may be recognised by their capitate inflorescences the flowers of which often open centripetally.
The flowers are small and polysymmetric, the sepals are spines or are thick and aerenchymatous, the outer layer of the tubular corolla is photosynthetic, the stamens are free, and the ovary is inferior.

 PBIO 450 Lecture Notes - Asteridae -- Spring 1999
While the near association of the Menyanthaceae is somewhat supported by the rbcL data, I am not inclined to muddy the water with the addition of a family that otherwise clearly fits in the Campanulanae.
The significance of the Calycerales (and therefore the Calyceraceae) is that here is the one group that probably points the way toward the evolutionary establishment of the Asterales (and therefore the Asteraceae).
A potential problem with using the Calycerales as a near relative to the Asterales is that the latter are probably primitively woody with opposite leaves whereas the Calycerales are herbs with alternate leaves.

Qualitative and quantitative data are presented for secondary xylem of 14 species of four genera of Calyceraceae.
Diversity in wood anatomy within Calyceraceae is explainable in terms of adaptation to particular ecological conditions.
The presence of pseudoscalariform pitting, with transitions to helical-banded secondary xylem vessels, very much like those of primary xylem, in Boopis graminea and Nastanthus spp., coupled with absence of libriform fibers (replaced by axial parenchyma) are probably related to expansion and contraction of the wood in response to fluctuation in moisture availability.

The sister group to Asteraceae, Calyceraceae, and a second family Valerianaceae, exhibit wall structure types most similar to that of Tubuliforidites.
It is possible that the reticulate layer in Barnadesioideae and Mutisieae is not homologous to the condition found in Calyceraceae, Valerianaceae, and Tubuliforidites.
Grains of Calyceraceae, Valerianaceae, and Tubuliforidites appear to have a reticulate exine layer that is derived from divisions of the upper portion of columellae.

Expanded sampling of Calyceraceae and Asteraceae, in addition to past ultrastructural studies of Asteraceae, provide an excellent data base for examining trends in pollen morphology.
Using Calyceraceae and Goodeniaceae as outgroups, a phylogenetic analysis of all six tribes of subfamily Cichorioideae and subfamily Barnadesioideae was completed.
Looking at the distribution of ultrastructural features on tree topologies obtained from molecular phylogenetic analyses provide further insights to the evolutionary development of pollen types among basal lineages of Asteraceae.

The order Calycerales, with only the small family Calyceraceae (about 60 species), is of interest because of its role in speculation concerning the ancestry and relationships of the family Asteraceae.
The family Calyceraceae has sometimes been included in the Campanulales or in the Dipsacales, but it does not fit well in either.

Most of my research has focused on the systematics of Calyceraceae and the basal members of Asteraceae (sunflower family).
For my studies I have used morphology, pollen structure, wood anatomy, cytology, and distribution of Calyceraceae to understand the evolution of this small southern South American family of flowering plants.

Current work involves a biosystematic study of the endemic species of Lysimachia (Primulaceae) and qualitative and quantitative analyses of flavonoids in endemic Vaccinium species (blueberries) and in Metrosideros (Ohia lehua).
A long standing interest has been the flavonoid chemistry of Asteraceae (sunflower family) and relatives including the South American family Calyceraceae.

Phylogenetic analysis of a total of 24 sequences of rbcL identified a lineage consisting of two families, the Goodeniaceae and Calyceraceae, as the sister group to the Asteraceae.
In addition, a strongly supported major monophyletic clade consisting of Asteraceae, Goodeniaceae, Calyceraceae, Corokia (Cornaceae sensu Cronquist), Menyanthaceae, Lobeliaceae, and Campanulaceae was found.
These results clearly distance from the Asteraceae certain groups previously considered closely related; moreover, the results support alternative hypotheses of affinity that were based upon floral and inflorescence morphology, biogeography, pollen morphology, chemistry, and pollen-presentation mechanisms.
