Type locality: Not cited. 



Distribution: Chile. 



This species was sent from Santiago to Dr. Schumann by Dr. Karl Reiche in 1900 and 

 does not seem to have been very much distributed. It is a very remarkable plant, judging 

 from the illustration below cited, and may not be of this alliance. We know it only from 

 description and illustration.

6. Malacocarpus napinus (Philippi). 



Echinocactns napinus Philippi, Anal. Univ. Chile 41: 720. 1872. 

 Echinocactus mitis Philippi, Anal. Univ. Chile 85: 493. 1894. 



Plant 2 to 9 cm. high with a very large root, larger than the globose stem itself; ribs broken into 

 rounded tubercles; spines about 9, minute, 3 mm. long, appressed; flower small, about 3 cm. long, 

 pale yellow to nearly white ; flower- tube covered with minute scales, the axils long- woolly and bristly ; 

 stigma-lobes reddish. 



Type locality: Huasco, Chile. 



Distribution: Northern Chile. 



Echinocactus napinus and E. mitis both came from Huasco, and Schumann is probably 

 right in uniting them under the older name.
