Very nearly related to #. tristis, of which the female flowers alone are known, 
and only differing from that species in having several-flowered female racemes in 
place of solitary flowers. The male pedicels in this species are jointed high up as in 
H. aculeata. It is the only species of Hrythrococea with an extra-staminal ring of 
glands unaccompanied by inter-staminal ones.
