 Kakteenk. 14:99. 1904. 



Plant 2 to 7 meters high, when old quite spine- 

 less below, but very spiny toward the top ; trunk 

 usually very short, 2 to 2.5 cm. in diameter, its 

 outer layers pulpy and yellow, terete, with many 

 branches from near the base, these nearly erect 

 or more or less spreading and again branching; 

 ribs 12 to 15, no broader at base than above, some- 

 what tuberculate, separated by acute intervals; 

 areoles approximate, sometimes with only a very 

 little space between them, 5 to 10 mm. in diameter, 

 with short white wool, on many old stems and 

 branches the areoles die and fall, leaving a row of 

 indentations along the top of the rib; spines vari- 

 ous, on vigorous sterile shoots about 12 to 15 at an 

 areole, most of them about i cm. long, while i or 2 

 are very stout, porrect, elongated, and sometimes 

 12 em. long; on flowering branches the spines 

 numerous, soft and hair-like or some of them 

 bristle-like ; flowers borne near the tops of branches, 

 6 to 7 cm. long including the ovary; flower-buds 

 globular, covered with long, white, silky hairs; 

 inner perianth-segments white, short; fruit globu- 

 lar, 5 to 6 cm. in diameter, fleshy, said to be acid, 

 densely clothed with white hairs; seeds not know^n. 



Type locality: Iquique, Province of Taraj

 sea or rise from a narrow coastal plain, and is not found on the pampas, which extend east 

 of the coastal hills to the Andes. In both the Provinces of Antofagasta and Tarapaca, it 

 is the most conspicuous plant seen, in fact it is the only woody plant met with on their 

 western borders. It is called by the natives copado, and the old dead branches are carried
