Template:Short description Template:Speciesbox
Arrojadoa bahiensis is a species of plant in the family Cactaceae. It is endemic to Brazil. Its natural habitat is rocky areas.
Description
Arrojadoa bahiensis is a solitary cactus characterized by its green to gray-green shoots, which are spherical to cylindrical in shape. These shoots can grow up to 1.1 meters tall and have a diameter of 8 centimeters. They feature 9 to 14 rounded vertical ribs. Initially, the round areoles are covered with cream-colored wool, but they eventually become bare. The spines are finely needle-shaped and somewhat flexible, varying in color from yellowish to reddish, eventually turning gray. Each shoot has a central spine that can be up to 3 centimeters long, along with 6 to 11 radial spines that can reach up to 1.6 centimeters long, with older areoles containing as many as 23 spines that are either erect or spreading.
The cactus produces tubular pink flowers that appear near the top and along the upper sections of the shoots. These flowers measure between 3.2 and 3.9 centimeters in length and have a diameter of 8 to 10 millimeters, with white inner bracts. The fruits are round to egg-shaped, pink in color, and have a diameter ranging from 1 to 3 centimeters.[1]

Taxonomy
The species was first discovered in 1981. It was initially described as Floribunda bahiensis in 1993 by Pierre Josef Braun and Eddie Esteves Pereira.[4] The specific name "bahiensis" reflects its native range in Bahia. In 1994, Nigel Paul Taylor and Urs Eggli reclassified it into the genus Arrojadoa.[5]
