Reproductive biology in the primitive relic AngiospermDrimys brasiliensis (Winteraceae)

Plant Systematics and Evolution, 1980
From field observations onDrimys brasiliensis, principally in the Botucatu region of Sao Paulo State, Brazil, new data on the reproductive biology, the rhythm of growth, and the development of lateral cymose inflorescences, flowers and fruits are presented. Pollination accelerates the rate of flower-development for about 4–6 days.

INTEGUMENTARY STUDIES IN THE POLYCARPICAE: III. DRIMYS WINTERI (WINTERACEAE)

Acta Botanica Neerlandica, 1974
SUMMARY Drimys winteri has an anatropous, crassinucellate type of ovule with two non-vascularized integuments. Both the inner integument (i.i.) and the outer one (o.i.) are of dermal derivation. The integuments consist of three, or locally sometimes two or four layers of cells. The dermal initiation of the o.i.

A RECONSIDERATION OF THE GENUS TASMANNIA (WINTERACEAE)

TAXON, 1969
SummaryNew 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

Stamen venation in the Winteraceae

1987
Stamen venation is described for all species of Pseudowintera and an interspecific hybrid; the single species of Exospermum, several species of Belliolum, Drimys, Tasmannia (syn. Drimys sect. Tasmannia) and Zygogynum, as well as one species of Bubbia.

Fly pollination in Drimys (Winteraceae), a primitive angiosperm

1982
The primitive angiosperms are an assemblage of relictual plants considered to be representative of the earliest flowering plants (Stebbins 1974). These living fossils are distributed throughout the temperate and tropical regions of the world (Takhtajan 1969); an exceptionally large number of extant primitive angiosperms are concentrated in New Guinea ...

A new species of Zygogynum (Winteraceae)

1983
A new species, Zygogynum vinkii, is described within the woody Ranalean family Winteraceae. It differs from other species of the endemic New Caledonian genus in having 302-371 stamens per flower. Unspecialized cells of the lower leaf surface are covered with cuticular papillae of a type hitherto unreported in Zygogynum.

Epidermal leaf characters of the Winteraceae

1973
Leaf epidermal features (mostly studied in cuticular macerations) of 146 specimens, belonging to c. 33 species of all the 6 genera of the Winteraceae are described in detail. Typical for most representatives is the occurrence of alveolar material of cutinaceous nature overlying the cuticle proper, and usually occluding the stomata. Special attention is
