ECHINOFOSSULOCACTUS. 



II 9 



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 dietrichii. 



Illustration: Pfeiffer, Abbild. Beschr. Cact. 2: pi. 22 (fide Index Kewensis), as Echino- 

 cactus obvallatus.

Plant glaucescent, ovoid to oblong, 12.5 cm. high, 10 cm. in diameter with a depressed apex 

 covered with connivent spines ; ribs prominent, rather broad, obtuse, 14 to 22 ; spines 10, gray, 4 upper 

 spines subulate, of these 3 usually ascending, the central spreading or porrect, the largest 5 cm. long, 

 4 lower spines acicular; flowers and fruit unknown. 



Type locality: Mexico. 



Distribution: Probably eastern Mexico. 



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 adopted 

 by Salm-Dyck. The original Echinocactus gladiatus, based on Deppe's plant, is very dif- 

 ferent from Schumann's plant.
