Catharanthus roseus is an evergreen subshrub or herbaceous plant growing 1 m (39 in) tall. The leaves are oval to oblong, 2.5–9 cm (1.0–3.5 in) long and 1–3.5 cm (0.4–1.4 in) wide, glossy green, hairless, with a pale midrib and a short petiole 1–1.8 cm (0.4–0.7 in) long; they are arranged in opposite pairs.
Catharanthus is a genus of flowering plants in the family Apocynaceae.Like the genus Vinca, they are known commonly as periwinkles. [3] There are eight known species. Seven are endemic to Madagascar, [4] though one, C. roseus, is widely naturalized around the world.
The Open Tree of Life is an online phylogenetic tree of life – a collaborative effort, funded by the National Science Foundation. [2] [3] The first draft, including 2.3 million species, was released in September 2015. [4] The Interactive graph allows the user to zoom in to taxonomic classifications, phylogenetic trees, and information about a ...
Catharanthus roseus yields alkaloids used in the treatment of cancer. [22] [23] Tabernanthe iboga, Voacanga africana, and Tabernaemontana undulata contain the alkaloid ibogaine, which is a psychedelic drug which may help with drug addiction, but which has significant adverse effects, [24] [25] with ibogaine being both cardiotoxic and neurotoxic ...
The taxonomy of many groups is in a state of flux as taxonomic experts strive to incorporate the findings of Molecular phylogenetics, so it is not always possible to find a single satisfactory classification, and we would be doing a great disservice by pretending otherwise. The best would be to try and find out what the current consensus is, if ...
Vinca (/ ˈ v ɪ ŋ k ə /; [2] Latin: vincire "to bind, fetter") is an Old World genus of flowering plants in the family Apocynaceae, The English name periwinkle is shared with the related genus Catharanthus (and with the mollusc Littorina littorea). Some Vinca species are cultivated but have also spread invasively.
The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's On the Origin of Species (1859). [1]
It has been recorded on Madagascar periwinkle (Catharanthus roseus) and pequi (Caryocar brasiliense). [2] It has been observed as a pollinator of the fringed star orchid (Epidendrum ciliare) in Puerto Rico. [4] The caterpillar has several antipredator adaptations. Its consumption of toxic plants makes it distasteful to most predators.
