Discussion
This species is most closely related to H. juruensis, from which it differs in the much smaller leaves which are hirsutulous beneath, and to H. racemosa, but differs in the slightly bullate leaves, the hirsutulous lower surface of the leaves, and the larger more persistent bracteoles.
Flowering June to July. B
