The vexillavy stamen in this species is free at the base but not above ; it is
rather shorter than the others and bears a perfect anther ; the anthers of the 9 stamens
forming the sheath are alternately perfect and abortive; there are thus 5 perfect anthers
on the sheath and a sixth perfect anther on the vesillary stamen. This structure provided
Roxburgh with the excellent specific name that has usually been overlooked.
P a r t l y on this account, and partly on account of the interesting characters of the
plant, a copy is now given of Roxbui-gh's original figure.
