Drosera sect. Ergaleium
Encyclopedia
Drosera sect. Ergaleium is a section
of 26 species
that are erect or scrambling tuber
ous plants in the genus Drosera. This section represents a natural group and are taxonomically monophyletic.
The section description has its origins in the description of Drosera subg. Ergaleium
, first formally described by Augustin Pyramus de Candolle in 1824. In 1848, Jules Émile Planchon
reorganized the species into sections, series
, and subseries. Ludwig Diels
reclassified the genus in his 1906 monograph
of the family, placing the erect and scrambling tuberous Drosera in section Polypeltes. Another reclassification occurred in 1977, when Larry Eugene DeBuhr corrected Diels' section name to the correct and older autonym

Section (botany)
In botany, a section is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section, and the rank of series, if present, is below the section. Sections are typically used to help organise very large genera, which may have hundreds of species...

Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Tuber
Tubers are various types of modified plant structures that are enlarged to store nutrients. They are used by plants to survive the winter or dry months and provide energy and nutrients for regrowth during the next growing season and they are a means of asexual reproduction...
