Yungasocereus is a monotypic genus of cacti. Its sole species is Yungasocereus inquisivensis, native to Bolivia.[3]
Description[edit]
It is a columnar cactus, appearing either as a tree or shrub, ranging up to 4–5 meters in height. The 6–7 cm diameter stems are dark green, with 6-10 ribs. The 1.5–3 cm spines are in groups of 4-12, with no differentiation into central and radial types, and range from a brownish to grayish color. The flowers are white, appearing in groups of 5-8 near the stem tips. They open day and night and are 5 to 6 centimeters long.
The fruits have a length between 2 and 2.8 centimeters. They contain small, broadly oval, shiny black, slightly keeled seeds on the back, 0.9 millimeters long and 0.7 millimeters wide.[4]
Taxonomy[edit]
Martín Cárdenas described the species in 1957 from Inquisivi, placing it in Samaipaticereus.[5] Friedrich Ritter later found the same species in Yungas. In 1980, he gave the cactus its own genus, Yungasocereus.[6] After a period in Haageocereus, this was again separated into Yungasocereus.
Distribution[edit]
This cactus is known only from Yungas and Inquisivi provinces of La Paz Department, where it is found at elevations of around 1000 to 2300 meters.[citation needed]
