[4] Jens Klackenberg,[5] the botanist who formally described the species named it after the distinct coronal lobes of its flowers that resemble half the head of a spear (hasta in Latin).

Its many flowered, branching Inflorescences occur at the junction between the leaves and stem.

Its flowers have 5 hairless sepals that are connected at the base with broad, egg-shaped lobes that are 0.7–1 by 0.7–1 millimeters.

Its corona has 5 thread-like lobes that are 2–3 millimeters long with appendages at the top that point inwards.

The connective tissue between the chambers of the anther extends up into a rounded tip.
