[3] M. auristipulata is commonly found in Northern Chili[4] and rarely in Tacna, Peru.

[5] In general, the species range is very restricted as a result M. auristipulata is considered a rare plant.

[3][1] It is likely that there are less than 100 individuals left, classifying the species as critically endangered by the local government.

[1] The flowers of M. auristipulata are described as having tubes that are wider at the throat than the middle, a narrow corona, and blood red petals.

[5] The aerial tissues of M. auristipulata secretes a resin like exudate that has anti-inflammatory and antimicrobial properties, with higher efficiency when treating infections of gram positive bacteria than gram negative in vitro.
