EULYCHNIA. 



The only difference Dr. Rose was able to observe in the field between this species and 

 E. acida is the very woolly flower and fruit of E. spinibarbis. The flowers seemed to be 

 identical in form, size, and color and at La Serena the two were growing side by side; the 

 form with long silky wool on the flowers was never seen in the interior valleys, although 

 thousands of flowers were there observed. 



Cereus tortus (Forster, Handb. Cact. 391. 1846) may belong here. 



Cereus chilensis breviflorus (Hirscht, Monatsschr. Kakteenk. 8: 159. 1898) doubtless 

 belongs here, but has not been described.

 plant brought by Dr. Rose to the New York 

 Botanical Garden from the Botanical Garden 

 of Santiago, Chile, under the name Eulychnia 

 breviflora, in 1914. 



2. Eulychnia iquiquensis (Schumann). 



Cereus iquiquensis Schumann, Monatsschr. 

 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 1 2 to 1 5 at an 

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

 are very stout, porrect, elongated, and sometimes 

 12 cm. 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 known. 



Type locality: Iquique, Province of Tarapaca, Chile. 



Distribution: On top and slopes of the coastal hills in the Provinces of Atacama, 

 Antofagasta, and Tarapaca, Chile. 



According to published records, this species is known only from the original collection 

 made by Carlos Reiche in 1904, and has never been in cultivation. Dr. Rose collected 

 living, herbarium, and formalin specimens in 1914 not only at Iquique, but also at Anto- 

 fagasta. It grows only on the coastal hills, which at both towns come down almost to the 

 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
