N. Australia (or Queensland ?). Leichhardt, no station given. The specimens 
are not good, most of the flowers injured or deformed by insects, but the best appear to 
have the calyx-lobes, petals, and stamens very deciduous, as in H. ertceus, leaving a trun- 
cate fruiting calyx concealed within the persistent bracteoles.
