Marianthus erubescens is a glabrous, woody shrub or climber with reddish stems. Its adult leaves are narrowly elliptic, long and wide on a petiole up to long. The flowers are borne in groups of three to six on down-curved peduncles up to long, each flower on a pedicel long. The sepals are long, of unequal sizes, and fall off as the flowers mature. The five petals are red and joined to form a curved tube long. Flowering occurs from August to December and the fruit is a spindle-shaped capsule long.[1] [2] [3]
