 Echinocactus ambr^nus Hildmann in Schumann, Gesamtb. Kakteen 311. 1898. 



Globose, about 8 cm. irT&iameter, green, the apex covered with gray wool; ribs 20 or 21, some- 

 what compressed; areoles 6 to 20 mm. apart; radial spines 8, usually 10 to 12 mm. long; central 

 spines 1 or 2, 18 to 25 mm. long, stouter than the radials, all rigid, yellowish or grayish; flowers 

 yellow; outer perianth-segments acute, often recurved; inner perianth-segments lanceolate, erose, 

 or dentate. 



Type locality: Copiapo, Chile. 



Distribution: West coast of northern Chile. 



In the original description of Echinocactus ambiguus it is stated that the ovary is 

 probably scaly and woolly, but this is doubtless wrong. In all the species of Copiapoa, the 

 ovary is buried in a mass of wool but this arises from the areoles about the base of the 

 flower. This plant is known to us only from descriptions and figures. 



Echinocactus iiitricatus longispinus Monville (Labouret, Monogr. Cact. 178. 1853) 

 was referred here as a synonym.

? Echinocactus salm-dyckianus Pfeiffer, Abbild. Beschr. Cact. 2: under pi. 14. 1847. 



Simple, globose, very woolly at apex; ribs 8 to 13, straight, rounded, green; radial spines 5 to 7, 

 stout, straight or somewhat curved; central spine solitary, porrect, 3 cm. long; flowers pale yellow; 

 outer perianth-segments narrowly ovate, acute, reddish ; inner perianth-segments broadly oblong, 

 obtuse ; scales of ovary and flower-tube described by Schumann as woolly in their axils, but un- 

 doubtedly he is wrong. 



Type locality: Not cited. 



Distribution: Reported from Bolivia, but perhaps from that part of Bolivia now 

 belonging to Chile.
