[1] Cecarria obtusifolia is an aerial, stem-parasitic shrub, and like species in the genus Muellerina, it has epicortical runners.

[5] The inflorescence is axillary, with and a two-flowered umbel or a four-flowered raceme or spike; there are nearly orbicular bracts[5] beneath each flower.

The stamens are nearly equal, and the anthers are dorsifixed and versatile,[3] having a short sterile tip with the free part of the filament about 2 mm long.

Recorded hosts include plants in the genera: Calophyllum, Casuarina,[7] and Syzygium, and Xanthostemon.

[3] The leaves, which are blunt and rounded at the apex (tip), gave rise to the latin-derived name, obtusifolia, meaning "obtuse-leaved".
