Article Synopsis
  • The research focuses on the floral axis in the Malveae tribe, examining its classification and functional role, highlighting terminology discrepancies.
  • The study conducts ontogenetic, morphological, and histochemical analyses to clarify that the axis functions as an articulated pedicel, marked by a protuberance that allows for separation into two parts.
  • It reveals the presence of secretory extrafloral nectaries on the pedicel, which attract ants, and emphasizes the need for standardized terms to improve understanding in botanical studies.

Object-oriented programming (OOP) embodies a software development paradigm grounded in representing real-world entities as objects, facilitating a more efficient and structured modelling approach. In this article, we explore the synergy between OOP principles and the TypeScript (TS) programming language to create a JSON-formatted database designed for storing arrays of biological features. This fusion of technologies fosters a controlled and modular code script, streamlining the integration, manipulation, expansion, and analysis of biological data, all while enhancing syntax for improved human readability, such as through the use of dot notation.

The subtribe Ditaxinae in the plant family Euphorbiaceae is composed of five genera (, , , and ) and approximately 120 species of perennial herbs (rarely annual) to treelets. The subtribe is distributed throughout the Americas, with the exception of , which also occurs in tropical Africa and Madagascar. Under the current classification, Ditaxinae includes genera with a questionable morphology-based taxonomy, especially , and .

This study aimed to describe the origin, position, development and typology of inflorescences in Miconieae through ontogenetic and morphological analyses using light microscopy. We observed three morphological character states: terminal, pseudo-axillary and axillary; and two ontogenetic states: terminal and axillary. The terminal and pseudoaxillary inflorescences originate from terminal reproductive meristems.
