This species would appear to be best placed between A. tubero- 
sum, Eck. & Zey., and A. polyphyllum, Eck. & Zey. It is astouter 
plant, much more branched and leafy than the former; the flowers 
also are larger and dry pale, those of 4. tuberosum drying black ; 
the teeth of the calyx-lobes also are almost obtuse, not acumi- 
nate. From 4. polyphyllum it is distinguished by its rather less 
leafy character, narrower linear (not obovate) leaflets, and the 
more obtuse teeth of the calyx-lobes.
