Flower Structures of Averrhoa dolichocarpa Rugayah & Sunarti [PDF]
, 2022 Hermaphrodites are believed to be the ancestral characters of flowering plants. However, plants have developed spatially and functionally in arrangements to reduce the chances of self-fertilization. One well-known spatial arrangement is heterostyly. This

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]
, 2016 Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

Phylogeography of a Tertiary relict plant, Meconopsis cambrica (Papaveraceae), implies the existence of northern refugia for a temperate herb [PDF]
, 2011 The perennial herb Meconopsis cambrica, a western European endemic, is the only European species of the otherwise Himalayan genus Meconopsis and has been interpreted as a Tertiary relict species.

TAXON, Volume 75, Issue 2, April 2026.Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]
, 2018 Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.

Taxonomic decomposition of the latitudinal gradient in species diversity of North American floras [PDF]
, 2017 Aim: To test the latitudinal gradient in plant species diversity for self-similarity across taxonomic scales and amongst taxa. Location: North America. Methods: We used species richness data from 245 local vascular plant floras to quantify the slope and ...

Floral structure and systematics in four orders of rosids, including a broad survey of floral mucilage cells [PDF]
, 2018 Phylogenetic studies have greatly impacted upon the circumscription of taxa within the rosid clade, resulting in novel relationships at all systematic levels. In many cases the floral structure of these taxa has never been compared, and in some families,

Explosive Radiation of Malpighiales Supports a Mid-Cretaceous Origin of Modern Tropical Rain Forests [PDF]
, 2005 Fossil data have been interpreted as indicating that Late Cretaceous tropical forests were open and dry adapted and that modern closed-canopy rain forest did not originate until after the Cretaceous-Tertiary (K/T) boundary.
