COPIAPOA. 8 7 
Plants subcylindric, growing in clusters of 2 to 9, usually erect, but when old often 6 dm. long 
and spreading with ascending tips, about 12 cm. in diameter; ribs 8 to 12, low, separated by broad 
intervals; young areoles and tops of flowering plants filled with masses of soft brown hair; areoles 
large, approximate, the adjoining ones usually touching; spines 5 to 10, unequal, subulate, stout, the 
longer one 3 cm. long; flowers small, 2.5 cm. long; outer perianth-segments broad, obtuse, with red 
tips; inner perianth-segments yellow; stamens included; fruit naked, small, 8 mm. long; seeds black, 
shining. . 
Type locality: Chile. 
Distribution: Coastal hills of Antofagasta, Chile. 
The four species, referred above as synonyms of this one, were described between 
1845 and 1853 and may have come from the same source. ‘Two of them are said to have 
been from Bolivia, but at the time they were described, Antofagasta, now a part of Chile, 
belonged to Bolivia. Dr. Rose, when collecting in Chile in 1914 (No. 19410), found these 
plants very common on the dry hills above Antofagasta, and a number of fine specimens 
were sent to the New York Botanical Garden. 
We are following Pfeiffer in referring E. columnaris to this species. According to 
Pfeiffer, both species came from Valparaiso, Chile, but Dr. Rose could find no plant of 
this relationship about Valparaiso. Mr. Séhrens, whom he consulted, believes that 
Pfeiffer’s station was wrongly recorded.

3. Copiapoa coquimbana (Karwinsky). 
Echinocactus coquimbanus Karwinsky in Forster, Handb. Cact. ed. 2. 601. 1885. 
Plants clustered, forming mounds up to 1 meter broad and 6 dm. high, composed of several 
hundred heads; individual heads 12 cm. in diameter or less, pale green, at flowering time crowned by a 
dense mass of long white wool; ribs 10 to 17, obtuse, somewhat tubercled; radial spines 8 to 10, 
slender, straight or somewhat recurved; central spines 1 or 2, stouter, straight, 1.5 to 2.5 cm. long, 
black to gray ; flowers campanulate, 3 cm. long; outer perianth-segments distinct, linear, acute, green; 
inner perianth-segments oblanceolate, yellow, obtuse; tube nearly or quite wanting; filaments, style, 
and stigma-lobes yellow; ovary small, turbinate, naked. 
Type locality: Near the town of Coquimbo, Chile. 
Distribution: Province of Coquimbo, Chile. 
The Philippi Herbarium at Santiago de Chile has a specimen from Coquimbo, near 
La Serena, labeled ‘“‘Echinocactus cinerascens Lemaire,’’ which is doubtless to be referred 
here. E. cinerascens originally came from Copiapo, an interior town, much farther 
north than Coquimbo. Dr. Rose found this species very abundant on the hills near La 
Serena not far from Coquimbo (No. 19261). — 
Related to this species, and perhaps not distinct from it, is Echinocactus fiedlerianus 
Schumann (Gesamtb. Kakteen Nachtr. 121. 1903), but it grows farther north, not along 
the coast but in an interior valley. The type was collected by Mr. Sohrens near Vallenar, 
Huasco, Chile. Dr. Rose did not obtain specimens but he is now confident that this is 
the plant which he saw in great abundance just south of Vallenar. Schumann misunder- 
stood the relationship for he places it between Echinocactus megalothelos and EF. schicken- 
dantzii, two species of Gymnocalycium. It may be briefly characterized as follows: | 
i i ip-li ot, depressed-globose, grayish, covered with copious wool at 
the ae tne, we tlicreulete; aceoles depressed radial spines 4 to 7, 3 cm. long, subulate; flowers 
yellow, greenish without.
