ECHINOPSIS. 
63 
Usually simple, columnar, claviform, sometimes 1 meter high, 20 cm. in diameter, glaucous- 
green; ribs 10 to 15, acute, separated by acute intervals; areoles circular, filled with spines and short 
white wool; spines 8 to 15, the longest 2 cm. long, acicular, straight, pale, nearly white, except the 
tips, these brown; central spines 1 to several, the longest 3 to 4 cm. long, stouter than the radials. 
horizontal; young joints borne near the top of the plant, densely covered with yellow and brown 
spines intermixed with soft white hairs; flowers borne near the top of the plant, about 10 cm. long; 
inner perianth-segments spreading, lanceolate, acute, white. 
Type locality: Not cited. 
Distribution: Paraguay (fide Weber). 
This species is known to us only from descriptions and illustrations. Schumann 
follows Meyer in making E. forbesii a variety of E. valida. We have united the two and 
taken the older specific name 
The species was named for James Forbes (1773-1861), an enthusiastic student of 
cacti and gardener for the Duke of Bedford at Woburn Abbey. 
Cereus validissimus Weber (Diet. Hort. Bois 473. 1896) is given as a synonym of 
E. valida.

4. Echinopsis huottii (Cels) Labouret, Monogr. Cact. 301. 1853. 
Echinocactus liuotti Cels, Portef. Hort. 216. 1847. 
Echinopsis apiculata Linke, Woehenschr. Gartn. Pflanz. 1: 85. 1858. 
Plants simple, slender, up to 3.5 dm. high, short-columnar, dull green; ribs 9 to n, crenate; 
radial spines 9 to n, acicular, 2 cm. long or more; central spines normally 4, brown, 4 cm. long, 
subulate, porrect; flowers lateral, large, 17 to 20 cm. long, white; stamens included, greenish be¬ 
low, white above; style green; stigma-lobes 14, green. 
Type locality: Cited as Chile (fide Labouret), but doubtless wrongly. 
Distribution: Bolivia (fide Linke and Schumann). 
It does not seem close to any of the other species. It is quite different from the Boli¬ 
vian species collected by Dr. Rose at La Paz, Bolivia, which we have referred to E. 
bridgesii. (See page 74.) 
We have studied a plant sent to the New York Botanical Garden from the Berlin 
Botanical Garden in 1902; in this there is only one central spine at each areole. 
Schlumberger (Rev. Hort. IV. 3: 348. 1854) calls this Echinopsis kuottii, doubtless a 
typographical error. 
Cereus huottii Cels and Echinopsis verschafifeltii (Diet. Hort. Bois 471. 1896) are 
given as synonyms of this species by Weber.

5. Echinopsis minuana Spegazzini, Anal. Mus. Nac. Buenos Aires III. 4; 488. 1905. 
Simple or rarely proliferous at base, columnar, 5 to 8 dm. high, 14 to 15 cm. in diameter; ribs 12, 
straight, a little undulate; spines all straight, dark brown to chestnut-colored; radial spines 4 to 7, 
short, 2 to 3 cm. long; central spine solitary, stouter than the radials, bulbose at base, 5 to 6 cm. long; 
flowers large, inodorous, 20 cm. long; inner perianth-segments oblanceolate, 4.5 cm. long; filaments 
and style greenish white; stigma-lobes 17 or 18, greenish white; fruit subglobose, 4.5 cm. long, 
greenish red. 
Type locality: Bank of Parana River, province of Entre Rios, Argentina. 
Distribution: Province of Entre Rios, eastern Argentina. 
We know this species only from description and a photograph taken by Dr. 
Spegazzini.
