Echinopsis salmiana Weber, Dict. Hort. Bois 472. 1896.

Cereus salmianus Cels in Weber, Dict. Hort. Bois 472. 1896, as synonym.

Echinopsis salmiana bridgesii Schumann, Gesamtb. Kakteen 237. 1897.

Plants usually in clumps of 3 to 6, low, 1 dm. in diameter or more; ribs 10 to 12, high, not undulate; areoles large, filled with spines and short brown wool; spines about 10, brown when young, unequal; flowers 15 to 18 cm. long, probably white; tube slender, about the length of the limb; inner perianth-segments 3 to 4 cm. long, acute; scales on the ovary and flower-tube filled with long gray and black hairs.

Type locality: Bolivia.

Distribution: Bolivia.

The species was originally described from barren specimens. We believe that we have its flowers in the specimens collected by Mr. Bang. Plants were collected by Miguel Bang near La Paz, Bolivia, in 1890 (No. 176) and at the same locality by J. N. Rose, August 11, 1914 (No. 18844), also by Mr. Bang near Cochibamba, Bolivia, in 1901 (No. 2051). Dr. Rose's plant was without flower and its reference here is only tentative, but the habit of the plant was clearly that of the cespitose species of Echinopsis. Schumann, who studied Bang's plant, compared it with Cereus pasacana (see Cactaceae

2: 133. 1920) from which it is very distinct although the flowers resemble very much those of a Trichocereus.

27. Echinopsis mamillosa Gürke, Monatsschr. Kakteenk. 17: 128. 1907.

Stem simple, depressed- globose, 6 cm. high, 8 cm. in diameter, shining dark green, tubercled and unarmed at the apex; ribs 17, divided by deep furrows into acute tubercles; areoles 8 to 12 mm. apart, irregularly orbicular; radial spines 8 to lo, subulate, 5 to 10 mm. long; central spines 1 to 4, somewhat stronger and longer than the radials, all yellowish, brown at the apex; flowers 15 to 18 cm. long, white, rose-colored towards the apex of the segments; flower-tube funnelform, somewhat curved, green, bearing small ovate scales, these hairy in their axils; outer perianth-segments linear, brownish, spreading; inner perianth-segments oblong, apiculate; stigma-lobes yellow, linear, about 10.

Type locality: Bolivia.

Distribution: Bolivia.

We have not seen this plant, but have a colored sketch of the type made by Mrs. Gürke, July 16, 1907. Through some error, the Kew Bulletin (Kew Bull. Misc. Inf. App. 87. 1908) describes the flower as only three-fourths of an inch in length.

Although this species is formally described on page 135 of the Monatsschrift für Kakteenkunde, it is technically described a month earlier (p. 128). In fact, the flowers are much better and more fully characterized here than in the formal description.

Type locality: Mendoza, Argentina.

Distribution: Western Argentina.

We know the species only from descriptions and from some very poor illustrations. H. J. Elwes (Gard. Chron. III. 70: 199. 1921) states that there is a specimen in the Darrah Collection at Manchester that is 2 feet high. It has added but one inch to its height in the last 10 years. The specimen has been in England for 60 years.

Cereus gilliesii Weber (Dict. Hort. Bois 471. 1896) was given as a synonym of Echinop-sis formosa.

Melocactus gilliesii (Otto, Allg. Gartenz. 1: 364. 1833) and Echinocactus gilliesii and Echinopsis formosa gilliesii (Salm-Dyck, Cact. Hort. Dyck. 1844. 22. 1845) are usually referred to Echinopsis formosa.

Echinocactus formosus crassispinus Monville (Labouret, Monogr. Cact. 303. 1853) was published as a synonym of Echinopsis formosa spinosior and therefore doubtless belongs here.

Echinopsis formosa albispina Weber is mentioned by Schelle (Handb. Kakteenk. 118. 1907).

UNCERTAIN OR UNDESCRIBED SPECIES. Echinopsis MiECKLEYi R. Meyer, Monatsschr. Kakteenk. 28: 122. 1918.

Simple, ellipsoid to short-columnar, pale grayish green, 16 cm. high, 10 cm. in diameter; ribs 14, high, somewhat sinuous; radial spines usually lo, but sometimes 9 or 11, straight, 2.5 cm. long; central spine solitary, stouter than the radials, pale brown, sometimes whitish at tips, 5 cm. long; flowers and fruit unknown.

Echinopsis GiGANTEA R. Meyer, Monatsschr. Kakteenk. 29: 58. 1919.

Simple, ellipsoid to columnar, pale grayish green; ribs 8 to 11, high, broad at base, somewhat sinuous; radial spines 5 to 10; central spines sometimes 2, but usually solitary; flowers unknown.

Echinopsis saluciana Schlumberger, Rev. Hort. IV. 5: 402. 1856.

"Tube 15 to 16 cm. high, green, and covered with scales bearing tufts of brown hairs; sepals very numerous, lanceolate, 9 cm. long and 8 mm. wide at the base, dirty white with a central green stripe; petals 2 cm. wide and 6 cm. long, pure white; stamens yellowish; style short; stigma not projecting from the tube and having 12 yellowish-white stigma-lobes. The flower lasts but one day.

"With its large narrow sepals (?) and wide petals, the flower resembles very much more the flower of a Cereus than that of an Echinopsis."

A free translation of the original description is given above. Echinopsis Ducis paulii Förster, Handb. Cact. ed. 2. 641. 1885.

It is known only as a cultivated plant. Echinopsis tacuarembense Arechavaleta, Anal. Mus. Nac. Montevideo 5: 254. 1905.

Dull green, 10 cm. high, about 15 cm. in diameter; ribs 13, vertical; areoles 1 cm. apart; spines 9 or 10, 1 to 1.5 cm. long; central spine solitary; flowers white.

Type locality: Not cited.

Distribution: Uruguay.

Echinopsis albispina (Monatsschr. Kakteenk. 13: 144. 1903) is described as a white-spined, very interesting form.

Echinopsis beckmannii (Monatsschr. Kakteenk. 3: 103. 1893) and E. boeckmannii (Monatsschr.

Kakteenk. 3: 165. 1893) are only names and have never been referred to any described species.

Echinopsis boutillieri Parmentier (Förster, Handb. Cact. ed. 2. 622. 1885) is only a name. Echinopsis duvallii (Monatsschr. Kakteenk 1: 54. 1891) is from a seedling of unknown origin with pale rose flowers.

Echinopsis fobeana (Monatsschr. Kakteenk. 20: 190. 1910) 5 without description. A poor illustration is published by Möllers (Deutche Gärt. Zeit. 25: 475. f. 7, No. 20). Echinopsis formosissima Labouret (Rev. Hort. IV. 4: 26. 1855) probably does not belong to this genus. It originally came from Chuquisaca, Bolivia, although it is credited to Mexico by the Index Kewensis. Schumann refers it to Cereus pasacana Weber. Two illustrations of barren juvenile plants have been published (Möllers Deutsche Gart. Zeit. 25: 475. f. 7, No 9. and Monatsschr. Kakteenk. 4: 187. f. 2). Echinopsis longispina (Monatsschr. Kakteenk. 3: 127. 1893) is only a name.

Echinopsis muelleri (Monatsschr. Kakteenk. 6: 144. 1896) is a well-known garden form, presumably a hybrid. It is described in some detail in the Cactus Journal and illustrated (2: 7). Echinopsis nigricans Linke (Allg. Gartenz. 25: 239. 1857) is said to come from Chile. If so, it probably does not belong to this genus. Echinopsis paraguayensis Mundt (Monatsschr. Kakteenk. 13: 109. 1903) is briefly mentioned. Echinopsis polyphylla (Monatsschr. Kakteenk. 19: 144. 1909) is perhaps a hybrid. Echinopsis pyrantha (Monatsschr. Kakteenk. 4: 97. 1894) has not been described but has been said to be the most beautiful species of the genus. Echinopsis quehlii (Monatsschr. Kakteenk. 1: 55. 1891) is said to have been grown from Mexican seed. It is said to have beautiful pale rose flowers. If native to Mexico it must be referable to some other genus. Schelle lists it with the hybrids of E. eyriesii and E. oxygona. Echinopsis salm-dyckiana (Monatsschr. Kakteenk. 20: 142. 1910) is only a name. Echinopsis tougardii L. Herincq (Hort. Franc. 3: 193. pl. 17. 1853) is, according to Schumann, only a hybrid. It has very beautiful flowers. Echinopsis tuberculata Niedt (Allg. Gartenz. 25: 237. 1857), said to come from Bolivia, we do not know.

Echinopsis undulata (Monatsschr. Kakteenk. 11: 61. 1901) is briefly described as yellow-flowered and is probably a hybrid.

The three following names, although sometimes referred to Echinopsis, were evidently intended as species of Echinocactus. In all of them the generic name is abbreviated to "Ech." and, as they follow a species of Echinopsis, this abbreviation has naturally been taken to refer to that name. In each case, however, the species are referred to definite sections of Echinocactus as outlined by Salm-Dyck. Then, too, the gender of the specific name agrees with Echinocactus and not with Echinopsis. The three names are referred to Echinopsis by the Index Kewensis:

Ech. nodosus Linke, Wochenschr. Gärtn. Pflanz. 1: 85. 1858.

Ech. setosus Linke, Wochenschr. Gärtn. Pflanz. 1: 86. 1858.

Ech. haageanus Linke, Wochenschr. Gärtn. Pflanz. 1: 86. 1858.

The first two have been taken up formally in Echinocactus by Hemsley (Biol. Centr. Amer. Bot. 1: 535, 537. 1880) and the third by Rümpler (Förster, Handb. Cact. ed. 2. 469. 1885).

Echinopsis fischeri tephracantha and E. nigerrima are in the trade.
