Comparative structure of ovules and seeds inRafflesiaceae
The genera of theRafflesiaceae show a marked diversity in the structure of their ovules and seeds. Evolutionary trends are recognizable in ovule orientation and number of integuments. A change fromExpand

EMBRYOLOGY AND SEED DEVELOPMENT IN MAYACA FLUVIATILIS (MAYACACEAE)
SUMMARY The embryology and seed structure of Mayaca fluviatilis was studied. The embryological and structural seed characters clearly support the assumption of a separate familial status of theExpand

The Seed: Structure
The seed functions as the reproductive unit of the Spermatophyta (seed plants), and links the successive generations. Other important seed functions concern dispersal and survival under cold, dry orExpand

Development of ovule and seed in Rapateaceae
VENTURELLI, M. & BOUMAN, F., 1988. Development of ovule and seed in Rapateaceae. The structure of the ovules and/or seeds of twelve species of Rapateaceae were studied, some additional embryologicalExpand

Integument initiation and testa development in some Cruciferae
This study has shown for the first time that the middle layer (or layers) of the outer integument is (are) of subdermal derivation in at least some taxa of the Cruciferae. The outer integument isExpand

Seed Structure in Cannaceae: Taxonomic and Ecological Implications
The ovules and seeds of Canna show some striking differences to those in other zingiberalean families. The pachychalazal development of the ovule results in a seed of which only a small part of theExpand

An exploratory study on seed morphology of Miconia Ruiz & Pavón (Melastomataceae), with taxonomic and ecological implications
SUMMARY The results of an exploratory study on seed morphology of Miconia Ruiz & Pavon (Melastomataceae) are presented. Seeds of 75 species, mainly from north-western South America, includingExpand

Evolution and Phylogenetic Importance of Endocarp and Seed Characters in Viburnum (Adoxaceae)
Recent phylogenetic analyses based on molecular markers have resulted in a solid phylogeny of Viburnum with 12 well‐defined clades. This has allowed us to focus on character evolution, endocarp andExpand

Development of the ovule and seed in Costus cuspidatus (N.E.Br.) Maas (Zingiberaceae), with special reference to the formation of the operculum
The ovule primordium of Costus is trizonate and both its integuments are dermally initiated. With other evidence, this strongly suggests that most, if not all, monocotyledons have dermally initiatedExpand
