Lobivia pugionacantha, is a species of Lobivia found in Argentina and Bolivia.

Description

Lobivia pugionacantha typically grows individually, though it can also form clusters. The shoots are spherical to egg-shaped, with a cloudy gray-green color, reaching heights of 8 to 15 centimeters and diameters of up to 4.5 centimeters. These shoots develop a long taproot and have about 17 ribs. Each shoot bears four to seven light yellow spines, which can be quite variable in shape, sometimes resembling daggers. These spiness point sideways and can reach lengths of up to 2.5 centimeters or more.

The flowers of Lobivia pugionacantha are funnel-shaped and emit a fragrant scent during the day. They come in shades ranging from yellow to pink or orange-red, measuring up to 4.5 centimeters in both length and diameter. The spherical fruits are semi-dry and split open upon maturity.[2]

Distribution

This species is found in the Bolivian regions of Cochabamba, Chuquisaca, Potosí, Tarija, and possibly La Paz, as well as in the Argentine province of Jujuy at altitudes ranging from 3500 to 4000 meters.

Taxonomy

First described as Echinopsis pugionacantha in 1931 by Joseph Nelson Rose and Friedrich Bödeker, the specific name "pugionacantha" is a combination of the Latin word "pugio," meaning 'dagger,' and the Greek word "akantha," meaning 'thorn.' Curt Backeberg later reclassified the species under the genus Lobivia in 1936.[4]
