It is characterized by sepals densely covered with long eglandular hairs (not long glandular hairs), pedicels bearing retrorse and crispate hairs and lacking glandular hairs with only sparse subsessile glands, and mericarps that are almost hairless, bearing only very sparse subsessile glands rather than dense glandular indumentum.
