ECHINOFOSSULOCACTUS. 11g 
Type locality: Mexico. 
Distribution: Mexico. 
Pfeiffer in 1837 attempted to identify Echinocactus obvallatus with certain plants then 
in the Schelhase collection, but later when he figured his plant he questioned this identifi- 
cation, although he did not rename it. Dietrich, however, in 1839, named the Echinocactus 
obvallatus Pfeiffer in part, as above. 
Echinocactus lancifer was used by Reichenbach (in Terscheck, Suppl. Cact. 2), but 
whether properly described or not we do not know. The name was, however, formally 
published by Walpers in 1843 (Repert. Bot. 2: 320), but this date was after Dietrich had 
published his name. Heynhold evidently considered Reichenbach’s name properly pub- 
lished for he changed Dietrich’s name to Echinocactus dietrichit. 
Illustration: Pfeiffer, Abbild. Beschr. Cact. 2: pl. 22 (fide Index Kewensis), as Echino-

Schumann in his monograph does not take for this name the plant as originally de- 
scribed and figured by Link and Otto, but a later description used. by Pfeiffer and adopte 
by Salm-Dyck. The original Echinocactus gladiatus, based on Deppe s plant, is very dif- 
ferent from Schumann’s plant.
