The classification of the Opuntioideae is thus uncertain as of March 2012; Griffith and Porter say that changes in classification will require "broad information (of multiple data types) regarding all species of opuntioid cacti". [8] The ICSG classification divides the subfamily Cactoideae into nine tribes. However, phylogenetic research has ...
Acanthocereus tetragonus is a tall, columnar cactus that reaches a height of 2–7 m (6.6–23.0 ft). Stems are dark green, have three to five angles, and are 6–8 cm (2.4–3.1 in) in diameter. Stems are dark green, have three to five angles, and are 6–8 cm (2.4–3.1 in) in diameter.
Acanthaceae (/ æ k æ n ˈ θ eɪ s iː ˌ aɪ,-s i ˌ i /) is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions.
Three goals of plant taxonomy are the identification, classification and description of plants. The distinction between these three goals is important and often overlooked. Plant identification is a determination of the identity of an unknown plant by comparison with previously collected specimens or with the aid of books or identification manuals.
In 1840 Edward Hitchcock inserted a paleontological chart in his Elementary Geology (1840). [4] It shows a branching diagram of the plant and animal kingdom against a geological background. The tree of life image that appeared in Darwin's On the Origin of Species, 1859; Early classification chart are often visualized in a tree structure.

A pioneering system of plant taxonomy, Linnaeus's Systema Naturae, Leiden, 1735. This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a ...
