An Ultrastructural Study of the Phloem of Drimys (Winteraceae)
IAWA Journal, 1985The ultrastructural features of mainly primary phloem of three species of Drimys (Winteraceae), D. winteri J. R. ' G. Forst., D. lanceolata (Poiret) Baill. and D. granadensis L. f. var. mexicana (DC.) A. C. Smith are similar to those usually observed in dicotyledons.

Journal of Biogeography, 2017
AbstractAimWinteraceae comprise c. 130 species in seven genera, with the greatest species diversity in the Pacific (Pseudowintera, Zygogynum), Australia (Bubbia, Tasmannia), New Guinea (Belliolum, Bubbia, Zygogynum, Tasmannia) and Madagascar (Takhtajania). Only Drimys occurs in South America. Because of their Cretaceous leaves, wood and pollen fossils,

A New Species of Zygogynum (Winteraceae) from New Caledonia [PDF]
Blumea: Journal of Plant Taxonomy and Plant Geography, 2003 Treelet 3–8 m high. Branchlets rather slender; dry epidermis blackish brown, longi tudinally wrinkled, cells laterally distinct, almost flat. Cataphylls (strongly reduced leaves), but usually their scars, between and below the leaves. Leaves scattered.

Molecular Ecology, 2010 Few chloroplast-based genetic studies have been undertaken for plants of mesic temperate forests in the southern hemisphere and fossil-based models have provided evidence of vegetation history only at the broadest scales in this region.

A RECONSIDERATION OF THE GENUS TASMANNIA (WINTERACEAE)
TAXON, 1969SummaryNew chromosome counts based on collections of Winteraceae have strengthened the conclusion, suggested by morphological and anatomical study, that the two Sections (Tasmannia and Drimys) traditionally treated in the genus Drimys J. R. & G. Forst. are very distinct and merit full generic status. Consequently Tasmannia R. Br. ex DC. is herewith

Carpel Development in Tasmannia insipida (Winteraceae)
International Journal of Plant Sciences, 1996Angiosperm carpels are closed (sometimes barely so) saclike structures, sometimes with a long ventral stigmatic crest. Interpretation of winteraceous carpels, particularly those of Tasmannia (synonym Drimys sect Tasmannia) piperita, has been critical to both ontogenetic and phylogenetic theories regarding general carpel development.

О РОДЕ PSEUDODRIMYS (WINTERACEAE)
2015New data on the morphology and anatomy of the fruits and seeds argues for exclusion of the aberrant (incertae sedis) species Tasmannia purpurascens (Vickery) A.C. Sm. (=Drimys purpurascens Vickery) from the genus Tasmannia R. Br. ex DC. (Winteraceae Lindl.). The species is transferred into the genus Pseudodrimys Doweld.
