Discussion

The naming of new species refers to the main character of this species i.e. sessile or sitting cephalium. This species closely related with F. rigidifolia and F. pectinata and included in section Hemsleya because it has a pectinate spinulose auricle. The differences of Freycinetia sessiliflora with F. rigidifolia and F. pectinata are the size of leaves, tip of auricle, shape of bractea, number of stigma and pres- ence of pedicellus (Table 1).
