[2] M. angustisecta is a pale green woody shrub can grow up to 0.5 meters tall.

[3] Visually, it is very similar to M. tenuifolia, but can be identified by its broader calyx and higher crown.

[2][3] The first published description of the species dates to 1922[5] and Hermann Harms is accredited with its discovery.

[5] It was collected in 1915 at altitudes of 2350 m above sea levels in an area described as sparse of vegetation surrounded by other shrubs and cacti.

[2] Malesherbia angustisecta is currently considered endangered due to its restricted distribution.
