Description

The habit of the particular species, Magdalenaea limae, takes form of a perennial subshrub or shrub [1] . The stems are erect, rigid and branched.

The pale-green leaves are oppositely-arranged, subsessile, ovate and acute in shape. Leaves are usually thick, 2 to 3.5 centimeters long and 1.2 to 2.2 centimeters wide. Both sides are glabrous. Leaf margin is obscurely few-toothed.

Flowers form terminal axillary racemes. Flower bracts are smaller than leaves, yet similar. Pedicels are singular, erect when open, measuring 2.5 to 3 centimeters long each. Flower bracteoles are oppositely-arranged and lanceolate and 0.5 centimeters long, 1-1.5 millimeters wide. The calyx is green, spherical and are both smooth and glabrous. The calyx is twice as long as the flower's corolla at about 5 centimeters long.

The fruit is a spherical capsule, shortly acute, measured to be 1.5 centimeters wide and 1.7 centimeters long. The fruit bears multiple seeds, which are brown in color and have a brown testa (seed coat). [3]
