Grusonia F.Rchb. ex Britton & Rose (1919)
|🌵 Author(s)||Joseph Nelson RoseNathaniel Lord Britton|
|🌵 Type||Grusonia bradtiana|
Presumably named for German entrepeneur and cactus collector Hermann Gruson (1821-1895).
The author of this name was without a doubt Friedrich Reichenbach (F.Rchb.) and not Heinrich Gustav Reichenbach (Rchb.f.), as is sometimes claimed.
