De Candolle's plate cited below, and may not be quite correct. This species, so far as 

 we are aware, has not been again collected. 



Cactus zinniaeflora Mocino and Sesse (De Candolle, Prodr. 3: 475. 1828) was given 

 as a synonym.

16. Pereskia horrida (HBK.) De Candolle, Prodr. 3: 475. 1828. 



Cactus horridus Humboldt, Bonpland, and Kunth, Nov. Gen. et Sp. 6: 70. 1823. 



Tree, 4 to 6 meters high, with terete slender branches ; spines often solitary, sometimes 2 or 

 3, slender, dark in color, unequal, the longest 2 to 3 cm. long; leaves solitary, alternate, 

 narrowly oblong, 3 cm. long, subsessile, entire, glabrous; flowers 3 to 5 together in upper axils, 

 about lo mm. long; calyx described as 5-toothed and persistent; petals 5 or 6, red, lanceolate, 

 spreading; fruit fleshy, many-seeded. 



Type locality: "Ad flumen Marahon prov. Jaen de Bracamoros." (Schumann says 

 this locality is in Peru.) 



Distribution: Northwestern South America. 



The above description is compiled from Kunth's original description and from notes 

 made by Dr. Rose upon the type material in the herbarium of the Museum of Natural 

 History at Paris, in which there are specimens from both Bonpland and Kunth. Both of 

 these sheets lack flowers and fruit, and only Kunth's bears leaves. So far as we are aware.
