In this thesis the development of the stamen is investigated, using structural and histochemical observations, micromanipulation and in-vitro culture.Formation and exposure of pollen are the two main goals of the developing stamen. The main processes of the pollen formation were already known.

Nordic Journal of Botany, EarlyView.We describe Stachytarpheta forzzae, a new species from an inselberg located in the municipality of Guaratinga, state of Bahia, within the Brazilian Atlantic forest. Morphologically, it resembles S. sprucei, the only other species of the genus known to inhabit inselbergs.

PLANTS, PEOPLE, PLANET, EarlyView.Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

PLANTS, PEOPLE, PLANET, EarlyView.The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

"Carpelloid stamens" in Lotus sp.
Acta Societatis Botanicorum Poloniae, 2014 The anatomy and cytology of flower buds in which one or two stamens underwent modifications of various degree, termed in the teratological terminology "carpelloid stamens" were analysed in <em>Lotus</em>. It is presumed that these disturbances were due to the hybrid character of the studied plants.

The Cinderella tree, Quillaja saponaria – A soap story
PLANTS, PEOPLE, PLANET, EarlyView.Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

Animating blossom: Time‐lapse to encourage plant awareness in the YouTube era
PLANTS, PEOPLE, PLANET, EarlyView.Time‐lapse videos can effectively capture key traits of flower blossoms, such as color, 3D structure, and temporal changes, making them valuable complements to herbarium specimens and other botanical collections. Despite the abundance of such videos on YouTube, most provide no ecological and botanical insights.
