* PUvjiobothrus was evidently intended, fiodpos beinjr the word for pit or liollow, 

 and tliere is no Greek word answering to bolhrys. Ahhough we may not correct 

 tlie form of tlie name, we must hold to the masculine gender. Although tiie 

 name, in its original application to the hollow in the face of the nutlet, is good 

 only for the single original species, it is not far amiss for the others also, in view 

 of tiie hollows left on the gynobase after the nutlets fall. These are shallow 

 pits or depressions, or areola} with raised borders, orbicular or nearly so except 

 in the first species, in two or three of them with the borders so tliickcned or 

 salient that the gynobase after the nutlets fall is cruciform wlicn all four nutlets 

 mature. More commonly only one or two nutlets ripen.
