***Vatricania*** is a [monotypic](/source/Monotypic_taxon) [genus](/source/Genus) of [flowering plants](/source/Flowering_plant) belonging to the family [Cactaceae](/source/Cactus). It contains just one species, ***Vatricania guentheri***.[2] It has the common name of **red tail cactus**.[3][4]

Its native range is [Bolivia](/source/Bolivia).[2][3] It is found in dry forest vegetation or covering hillsides, at altitudes of 800–1,300 metres (2,600–4,300 ft) metres above sea level.[5]

## Description

*Vatricania guentheri* is an [evergreen](/source/Evergreen), perennial columnar cactus.[3][4][6] It can grow up to 2 m (6 ft 7 in) tall.[3] Branching occurs from the base, with pale green stems up to 10 cm (4 in) in diameter.[4] It has about 27 ribs.[3][4][6] The flowers are initially borne in a [cephalium](/source/Cephalium) (reddish brown wool,[4]) running down from the crown (top of the plant) on one side, of the branches,[3] later in a superficial dome cephalium.[6] It blooms during the early summer and develops yellowish whitish flowers that get up to 8 cm long and 5–3 cm (2–1 in) in diameter.[3] The flowers are yellowish white areoles or funnel shaped flowers,[4] with 25 spines, 5–22 mm (0–1 in) long.[3][4] It has edible fruit.[4]

## Taxonomy

Flower of the plant

The genus was first described and published in 1950 by [Curt Backeberg](/source/Curt_Backeberg).[2] The genus name *Vatricania* is in honour of [Louis Félix Vatrican](https://en.wikipedia.org/w/index.php?title=Louis_F%C3%A9lix_Vatrican&action=edit&redlink=1) (1904–2007), an agricultural engineer from [Monaco](/source/Monaco), director of the national [Jardin Exotique](/source/Jardin_Exotique_de_Monaco).[7] The genus is placed in the tribe *Trichocereinae*.[8]

In publishing the genus name, Backeberg designated *Cephalocereus guentheri* as the [type species](/source/Type_(biology)), although he did not actually use the combination *Vatricania guentheri*,[9] which he published in 1951. *Cephalocereus guentheri* was first described by Kupper in 1931.[1] The Latin [specific epithet](/source/Binomial_nomenclature) *guentheri* refers to Ernesto Günther of [Valparaíso](/source/Valpara%C3%ADso), Chile, who financed the expedition in Bolivia during which Carl Troll discovered the species. Kupper originally spelled the epithet *Güntheri*.[10]

The species was lumped into *Espostoa* in 1959.[11][5][12] A hybrid origin was suggested as there are differences from *Espostoa*.[13] Molecular evidence suggests that *Espostoa* is not the correct placement for this species.[11]

## Cultivation

Cephalium

Can be grown in the USA,[4] in Zone USDA: 9b-11.[3] It can survive a minimum average temperature of 55°F (12°C) and can tolerate positions in full sun.[3]
