Journal ArticleDOI
Anatomical variation in Cactaceae and relatives: Trait lability and evolutionary innovation
TL;DR: It is hypothesized that high lability of many putative "precursor" traits may have been critical in generating the organismal context necessary for the evolution of an efficient and integrated photosynthetic stem.
Journal ArticleDOI
Valdivian ecosystems in the Late Cretaceous and Early Tertiary of Antarctica: further evidence from myrtaceous and eucryphiaceous fossil wood
TL;DR: In this article, the first occurrences of myrtaceous and eucryphiaceous wood taxa from the Maastrichtian-Palaeocene sediments of the James Ross Basin were reported.
Journal ArticleDOI
Characterization and Palaeoecological Significance of Archaeological Charcoal Assemblages during Late and Post-Glacial Phases in Southern France
TL;DR: In this article, the results of the charcoal analysis, based on the identification of woody species from anatomical features, contribute to the elaboration of plain phases within the development of vegetation in southern France.
Journal ArticleDOI
The floral nectary of Hymenaea stigonocarpa (Fabaceae, Caesalpinioideae): structural aspects during floral development.
TL;DR: Starch hydrolysis contributes to nectar formation, in addition to the photosynthates derived directly from the phloem, in these nectaries, the secretion is an energy-requiring process.

Phylogeny of the asteridae s. str. based on rbcl sequences, with particular reference to the dipsacales
Anders Backlund,Birgitta Bremer +1 more
TL;DR: TherbcL gene was sequenced and analyzed cladistically together with a large sample of genera representing all main clades of the subclassAsteridae in order to determine more precisely the delimitation of the orderDipsacales and to elucidate the phylogeny of the families within the order.
