on both sides, papillae longish ; nerve thin, vanishing below apex, cells 

 very small, roundish-quadrate, the basal elongated, diaphanous. Cap- 

 sule pale becoming brownish, on a flexuose pale pedicel, erect or 

 subcernuous, oval and oblong, striate, the neck inconspicuous, not 

 strumose ; lid long beaked, smooth at margin, annulus persistent, of 

 2 rows of cells ; teeth 2 rarely 3 fid below middle, rufous red, 

 remotely articulate.

This was sent as O. poly carpus 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 ar eolation. O. poly carpus has the 

 leaves papillose only on the back towards apex, while in O. gmcilescens 

 both surfaces are distinctly so. It will doubtless be met with in other places 

 now that attention is drawn to it.
