Echinopsis bridgesii often grows in groups and forms three to six shoots from the base. The spherical to elongated shoots reach heights of up to 40 centimeters with a diameter of 13 centimeters. There are nine to twelve distinct ribs , notched or not notched. The large areoles on it are brown. From them arise short and conical or longer and needle-like thorns of up to 2 centimeters in length. The mostly single central spine, sometimes it is missing or several are formed, is gray and tipped darker. The eight to ten very unequal radial spines are brown.

The white flowers open at night. They are six to eight inches long.

Distribution, systematics and endangerment

Echinopsis bridgesii is widespread in the Bolivian department of La Paz in dry valleys and the Puna vegetation at altitudes of 2900 to 3200 meters.

The first description by Joseph zu Salm-Reifferscheidt-Dyck was published in 1850.

A nomenclature synonym is Lobiviopsis bridgesii (Salm-Dyck) Frič (no year, nom. Inval. ICBN -Article 43.1). Further synonyms are Cereus salmianus Cels (no year), Echinocactus salmianus Cels (1847) and Echinopsis salmiana F.ACWeber ex Rud.Meyer (1895).

Subspecies

The following subspecies are distinguished:

Echinopsis bridgesii subsp. bridgesii

Echinopsis bridgesii subsp. bridgesii
The shoots of this subspecies are up to 40 centimeters long and reach a diameter of 13 centimeters. The up to twelve ribs are not notched. The needle-like, gray to brownish thorns are up to 2 centimeters long. The flowers are up to 18 centimeters long.

Synonyms are Echinopsis bridgesii var. Tenuispina F.Ritter (in sched., No year, nom. Inval. ICBN -Article 29.1), Trichocereus tenuispinus F.Ritter (1967) and Trichocereus tenuispinus var. Pajonalensis F.Ritter (1967).

In the Red List of Threatened Species of the IUCN , the species is listed as " Least Concern (LC) ". H. listed as not endangered. Echinopsis bridgesii subsp. yungasensis
The first description as Echinopsis yungasensis by Friedrich Ritter was published in 1980. Pierre Josef Braun and Eddie Esteves Pereira presented the species in 1995 as a subspecies to Echinopsis bridgesii . The subspecies is only distributed in the lowlands of the provinces of Nor-Yungas and Sud-Yungas . The shoots are 20 to 40 centimeters high and 7 to 13 centimeters in diameter.
