MALACOCARPUS. 203 



Type locality: Stony hillslopes near Valparaiso, Chile. 



Distribution: Along the coastal hills of central Chile. 



Dr. Rose found this plant very common in two localities in central Chile. One was in 

 pasture on the hills above Valparaiso, altitude about 1,000 feet; the other was on the edge of 

 cliffs about Valparaiso Harbor and only about 20 feet above the water. In the latter 

 locality it was associated with Ncoporteria subgibbosa. 



Under Eckinocactus soehrensii, Haage and Schmidt (1920) offer for sale the varieties 

 albispinus, brevispinus, and niger. 



Cactus horridus Colla, Eckinocactus tuberisulcatus Jacobi, and E. soehrensii were all 

 based upon plants from Valparaiso and we believe we are justified in combining them under 

 the oldest specific name available.

Eckinocactus froeklichianus Schumann, Gesamtb. Kakteen Nachtr. 124. 1903. 



Simple or clustered, subglobose or short-columnar, 15 cm. high, pale green; ribs 16, broad and 

 obtuse, divided into large tubercles ; spines 15, all radials, or at least no very definite central ones, 

 straight or somewhat curved, flexuous; flowers yellow or reddish brown, large, 3 to 6.5 cm. long; 

 perianth-segments lanceolate, acute; stigma-lobes green; scales on the flower-tube and ovary small, 

 scattered, bearing short wool and setae in their axils. 



Type locality: Chile. 



Distribution: Chile. 



Mr. Sohrens tells us that he obtained the specimens, which were named Eckinocactus 

 froeklichianus, from the mountains south of Santiago and that he now considers the species 

 the same as Eckinocactus curvispinus. 



Bertero's type of Cactus curvispinus is preserved in the museum at Santiago. It con- 

 sists of one small fragment bearing two clusters of spines and one flower ; the spine-cluster 

 contains 10 or 11 spines, the longest of which is 2 cm. long; the flower is 3 cm. long with the 

 ovary bearing small scales with woolly axils and the uppermost scales bearing bristles in 

 their axils.

Subglobose to short-cylindric, bright green; ribs about 14 to 16, broad, obtuse, strongly tuber- 

 cled ; areoles rather large, felted ; spines about 7, short, spreading, slender ; flowers large, yellowish red ; 

 perianth-segments oblong, obtuse; ovary bearing small scales with a little wool in their axils. 



Type locality: Chile. 



Distribution: Chile. 



This species was introduced by a Mr. Hitchen from Chile and flowered in 1836. 



The status of this species is very confusing. It was described very briefly by Hooker 

 who had never seen the living plant ; its exact habitat was not given and it has never with 

 certainty been re-collected.
