Notes:
This species is characterized by its glabrescent habit, distinctive stipules united around the stem into a well developed tube with a group of glandular appendages near the base of each interpetiolar side, elliptic subsessile leaves, subsessile axillary inflorescences that are subcapitate to shortly cymose, short lobed calyx limbs, salverform corollas with the tube 5-7 mm long,and ovoid fruits 6-10 mm long. The authors note that the inflorescences are paired at nodes well below the stem apex, and thus agree with the axillary arrangement in other Rubiaceae genera and represent a mophological novelty in Rudgea and perhaps Palicoureeae.
