Anatomy of the Strelitzia reginae flower (Strelitziaceae)

open access: yesNordic Journal of Botany, 1986
The Strelitzia reginae Ait. flower has many remarkable structural spezializations, the histology and cytology of which we have investigated. The chromoplasts of the sepals are conspicuously elongated and enclose numerous carotenoid tubules parallel to the ...

Phylogenetic Relationships and Evolution in the Strelitziaceae (Zingiberales)

Systematic Botany, 2012
Abstract Evolutionary trends and phylogenetic relationships in the Strelitziaceae (Zingiberales) were investigated using sequence data from ten plastid and two nuclear regions and a morphological dataset. The status of species of Strelitzia were evaluated in terms of the phylogenetic species concept. Relationships among the genera remain equivocal with

Pollen Grain Development and Tapetal Changes in Strelitzia Reginae (Strelitziaceae)

open access: yesAmerican Journal of Botany, 1989
The proexine that forms within the callosic envelope before the end of the microspore tetrad period is thick (about 1 μm) and exceptionally complex. It has components equatable with tectum, columellae, and a nexine that includes lamellar zones. All these components persist in the exine although late in development they become difficult to recognize ...

Exine, onciform zone and intine structure in Ravenala and Phenakospermum and early wall development in Strelitzia and Phenakospermum (Strelitziaceae) based on aborted microspores

Review of Palaeobotany and Palynology, 1997
Abstract The pollen grain wall of Ravenala and Phenakospermum , like Strelitzia , the better known member of Strelitziaceae, has a thin exine (about 0.1 μm), thick channeled zone (10–15 μm), and an intine (2–5 μm in thickness). We found aborted grains having thicker exines (0.3–0.7 μm) than mature grains of Phenakospermum and Strelitzia .

Inflorescence and Flower Development in Orchidantha chinensis T. L. Wu (Lowiaceae; Zingiberales): Similarities to Inflorescence Structure in the Strelitziaceae [PDF]

open access: yesInternational Journal of Plant Sciences, 2020
Premise of research. The monotypic Lowiaceae remains the least-known family in the plant order Zingiberales, yet it may hold an important key to unraveling the phylogenetic placement of the families Musaceae, Heliconiaceae, Strelitziaceae, and Lowiaceae.
