REMARKS
This subspecies has large, elliptic and moderately to strongly bullate leaf blades. It occurs from the north to south near the coasts, but I am unable to discern consistent differences between the northern and southern populations. Previously annotated specimens of this subspecies may bear the manuscript names Gossia “grandibullata” or Gossia clusioides subsp./ var. “grandibullata”. Unvouchered photos (Fig. 10D) of a possible specimen of this subspecies taken by J.-L. Ruiz near the River de Pirogues showed honeybees (Apis sp.) pollinating the flowers.
