Early floral development and androecium organization in Fouquieriaceae (Ericales)

Plant Systematics and Evolution, 2005
Early floral development with focus on the androecium was studied with the help of scanning electron microscopy and serial microtome sectioning in Fouquieria columnaris and F. splendens. Perianth organs appear in a spiral pattern on the floral apex. The spiral may be a clockwise or anti-clockwise.

Comparative androecium morphogenesis ofSicyos angulatus andSechium edule (Cucurbitaceae)

Botanical Magazine, 1992
“Androecium” ofSicyos angulatus andSechium edule is unique in having a solid central column below a head portion with thecae. Its morphogenesis was examined for the two species. The developmental course is composed of two distinct successive phases; (1) establishment of stamen primordia and (2) uplift of the stamen primordia caused by development of a ...

Androecium anatomy of Isertia laevis, a polysporangiate species of Rubiaceae

Protoplasma, 2020
In this study, we performed an anatomical analysis of the polysporangiate anthers and the development of pollen in Isertia laevis (Rubiaceae) with the aim to elucidate the internal structure of these atypical anthers. For this purpose, flowers in successive stages of development were dissected and the anthers were processed for conventional anatomical ...

Androecium and gynoecium anatomy of Bromeliaceae species

Flora, 2020
Abstract In this study, we performed a detailed anatomical analysis of the androecium and gynoecium in 16 species belonging to three out of the eight Bromeliaceae subfamilies, with a first-time description of the interlocular zone in anthers, a diagnostic character for Quesnelia and Aechmea species. Other potential taxonomic characters were observed:

OLIGOMERY AND VASCULATURE IN THE ANDROECIUM OF MOLLUGO NUDICAULIS LAM. (MOLLUGINACEAE)

Acta Botanica Neerlandica, 1982
SUMMARY The androecial morphology and vascular anatomy of Mollugo nudicaulis Lam. are examined in serial transverse sections. Androecia of this species can be arranged in a reduction series. The position and vasculature of stamens in some transitional cases show that oligomery is likely to proceed from fusion rather than non-production or abortion ...

Androecium development and staminode diversity of Cocculus orbiculatus (Menispermaceae)

Flora, 2020
Abstract The stamen is an extremely important reproductive organ in angiosperms. Androecia are the places where pollen is produced and show diversity in number and form; some are even reduced to staminodes or nectary structures in Ranunculales, but the development, morphology and structure of staminodes are completely unknown in Menispermaceae.

ANDROECIUM AND PISTIL CHARACTERS FOR TRIBE VICIEAE (FABACEAE)

TAXON, 1976
SummaryFive genera are recognized in the tribe Vicieae (Adanson) de Candolle ex Seringe (Fabaceae): Cicer Linnaeus, Lathyrus Linnaeus, Lens P. Miller, Pisum Linnaeus, and Vicia Linnaeus. A recently proposed genus, Vavilovia Fedorov, is placed in synonymy under Pisum, and a new subgenus is founded.

HISTOGENESIS OF THE ANDROECIUM AND GYNOECIUM IN DOWNINGIA BACIGALUPII

American Journal of Botany, 1968
A histogenetic investigation of the synandrous androecium and syncarpous gynoecium in the flower of Downingia bacigalupii Weiler (Campanulaceae; Lobelioideae) was undertaken for the purpose of comparing the modes of initiation, early growth and fusion in these floral whorls with that reported

Corolla and androecium development in someEudesmia eucalypts (Myrtaceae)

Plant Systematics and Evolution, 1989
In the early stages of ontogeny, the corolline parts of theEudesmia eucalypts develop as compound structures directly comparable to the early stages of the petals ofAngophora and the bloodwood eucalypts, but with the onset of androecial formation a marked difference takes place.
