Summary
This study reclassifies Macfadyenahispida as Dolichandrahispida, based on distinct morphological traits. This taxonomic update expands the Dolichandra genus to nine recognized species, aiding Neotropical plant identification.
Area of Science:
- Botany
- Plant Taxonomy
- Neotropical Flora
Background:
- Dolichandra is a genus of Neotropical lianas.
- The genus currently comprises eight species.
- Previous classifications included Macfadyenahispida within Dolichandrauncata.
Purpose of the Study:
- To re-evaluate the taxonomic status of Macfadyenahispida.
- To propose a new combination for Macfadyenahispida.
- To provide an updated taxonomic key for the genus Dolichandra.
Main Methods:
- Morphological analysis focusing on indument, ovary color, fruit length, and seed characteristics.
- Molecular data (implied by previous characterization).
- Taxonomic revision and proposal of new combinations.
Main Results:
- Macfadyenahispida is distinct from Dolichandrauncata.
- The new combination Dolichandrahispida (DC.) L.H. Fonseca & L.G. Lohmann, comb. nov. is proposed.
- The number of accepted species in Dolichandra increases to nine.
Conclusions:
- The morphological differences support the separation of Dolichandrahispida.
- An updated taxonomic key is provided for the nine species of Dolichandra.
- This revision clarifies the taxonomy of Dolichandra in Neotropical forests.

Taxonomy is the science of defining and naming groups of biological organisms based on shared characteristics. It uses a hierarchy of increasingly inclusive categories with Latin names. The smallest units of taxonomy, species and genus, are used to assign a formal, taxonomic name to each species in a system. This classification system, referred to as binomial nomenclature, was formalized by Carolus Linnaeus in the 18th century.

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

01:23Phylogeny
64.8K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
