Although SO generally united to O . polycarpus, this appears to be a good
species, distinguished by the constant presence of a struma, and the leaves at
their upper part papillose on both sides.

Glen Phee, Clova [Fergusson 1868).
This was sent as O. polycarpus by the Rev. Mr. Fergusson, as well as
true specimens of that plant, and hence it is probable that they grew together,
and at first sight it is not an easy matter to discriminate them. Perhaps the
distinction will be best apprehended by a comparison of the figures of the
leaves and bracts, and of their apices and areolation. O. polycarpus has the
leaves papillose only on the back towards apex, while in 0 . gracilescens
both surfaces are distinctly so. It will doubtless be met with in other places
now that attention is drawn to it.
