Browningia is a genus of columnar cacti in the family Cactaceae (order Caryophyllales), comprising around 11 accepted species native to western South America, particularly Colombia and Peru. The genus was described by Nathaniel Lord Britton and Joseph Nelson Rose in 1920 and named in honor of Webster E. Browning (1869–1942), director of the Instituto Inglés in Santiago, Chile.
Plants in Browningia are bushy to tree-like and almost always columnar, typically branching from a well-developed central trunk and reaching heights of up to 10 meters. The cylindrical shoots can measure up to 50 centimeters in diameter. The ribs are numerous and low, each bearing large areoles; those in the active growth zone are heavily armed with spines, while areoles in the reproductive zone typically carry few spines or none at all, a dimorphism characteristic of the genus.
The flowers are tubular to bell-shaped, ranging in color from white to purple, and open at night — an adaptation associated with bat or moth pollination. The flower tube is slightly curved and the areoles on the flower cup and tube are nearly bare. Fruits are usually small and variable across species.
Browningia is represented in cultivation primarily as a specimen plant for large collections, prized for its distinctive candelabra-like silhouette. Well-known members include Browningia candelaris, the candelabra cactus of the Atacama Desert borderlands, and Browningia hertlingiana, notable for its powder-blue stems.
Etymology
The genus Browningia was named by Britton & Rose (1920) in honor of Webster E. Browning (1869–1942), a British-American educator who served as director of the Instituto Inglés in Santiago, Chile. The name commemorates his contributions to education in South America rather than any botanical work.
Distribution
Browningia is native to western South America, with GBIF distributions recorded from Colombia and Peru. The genus is associated with Andean and pre-Andean arid zones, consistent with the habitats of well-documented members such as B. candelaris, which occurs in the Atacama Desert region of Peru and northern Chile.
