HARDLY A RELICT: FREEZING AND THE EVOLUTION OF VESSELLESS WOOD IN WINTERACEAE
Evolution; International Journal of Organic Evolution, 2002 The Winteraceae are traditionally regarded as the least-specialized descendents of the first flowering plants, based largely on their lack of xylem vessels. Since vessels have been viewed as a key innovation for angiosperm diversification, Winteraceae have been portrayed as declining relicts, limited to wet forest habitats where their tracheid-based ...

Pharmacological and toxicological studies of Drimys angustifolia Miers. (Winteraceae)
Journal of Ethnopharmacology, 2007 Drimys angustifolia Miers. (Winteraceae) is a Brazilian medicinal plant used as analgesic, antiulcer and anti-inflammatory without studies to assure its efficacy and safety Leaf and stem bark extracts were evaluated to determine the antiulcer, analgesic, antiinflammatory and antioxidant activities.

Journal of Biogeography, 2014 Aim: Our aim was to implement a molecular dating analysis and assess divergence times among taxa of Winteraceae. This enabled us to test hypotheses of vicariance versus long-distance dispersal to explain intercontinental disjunctions in the family ...

The First Record of Fossil Wood of Winteraceae from the Upper Cretaceous of Antarctica
Annals of Botany, 2000 Fossil wood of the Winteraceae from the Upper Cretaceous sediments of James Ross Island, Antarctic Peninsula, is described here for the first time. The specimen is characterized by the absence of vessels, rays of two distinct sizes and tracheids with one–

Leaf flavonoid patterns in the winteraceae
Phytochemistry, 1982Abstract In a leaf flavonoid survey of 59 specimens of the Winteraceae and related families, representing nine genera, luteolin 7,3′-dimethyl ether (in 77%) and flavonols (in 81%) were found to be major constituents. Indeed the high incidence of luteolin 7,3′-dimethyl ether chemically isolates the family from all other angiosperm groups, including ...

Cytotoxic sesquiterpenoids from Winteraceae of Caledonian rainforest
Phytochemistry, 2009One secobutanolide, two butanolides and six drimane sesquiterpenoids were isolated from the bark and leaves of Zygogynum pancheri and Zygogynum acsmithii (Winteraceae) along with six known drimanes, isodrimanial, 1beta-O-p-methoxy-E-cinnamoyl-bemadienolide, 7-ketoisodrimenin, drimenin, polygodial and 1beta-E-cinnamoyl-6alpha-hydroxypolygodial.
