The typical subspecies, known only from the Kaieteur Gorge, has subulate external calyx teeth 1.8 mm long and the ovary apex with a lobulate corona tipped with numerous glandular hairs 0.3-0.5 mm long. A n isotype of the Potaro endemic (Sandwith 1268, NY) shows some gland-tipped hairs on the external calyx teeth, as well as incurved-setose stem and inflorescence pubescence; however the topotypical Maguire & Fanshawe 23075 lacks glandular calyx hairs and has appressed stem and inflorescence indument. In subsp. tepuiensis, there is similar variability in the degree of hair appression; there also is variability in the density of the lower leaf surface hairs, some of the paratypes being sericeous-strigose but with no concomitant floral differentiation.
