NEOPORTERIA. 99 



6. Neoporterla chilensis (Hildmann). 



Echinocactus chilensis Hildmann in Schumann, Gesamtb. Kakteen 423. 1898. 

 Simple or proliferous at base, globose to short-columnar, woolly at apex; ribs 20 or 21, crenate, 

 pale green; radial spines about 20, somewhat acicular, 1 em. long; central spines 6 to 8, 2 cm. long; 

 flowers pink, 5 cm. broad when fully expanded; perianth-segments narrow, acute, the inner ones 

 toothed toward the apex; filaments white, short; style white, with yellow stigma-lobes; the scales of 

 the ovary and flower-tube bearing in their axils short wool and some of them a long white hair much 

 longer than the scale. 



Type locality: Chile. 



Distribution: Western part of the Andes of Chile. 



This species was originally described as having yellow flowers and naked scales but 

 this was evidently an error. 



E. chilensis confinis Hildmann (Schumann, Gesamtb. Kakteen 424. 1898) is said to 

 differ from the species in its shorter yellow central spines.

7. Neoporteria fusca (Miihlenpfordt). 



Echinocactus fuscus Miihlenpfordt, Allg. Gartenz. 16; 10. 1848. 

 Echinocactus ebenacanthus Monville in Labouret, Monogr. Cact. 253. 1853. 

 Echinocactus humilis Riimpler in Forster, Handb. Cact. ed. 2. 471. 1885. 



Globular to short-cylindric, about 10 cm. in diameter; ribs 12 or 13, dark green, somewhat 

 tubercled; radial spines 5 to 7, more or less ascending, brownish; central spines 4, black when young, 

 3 cm. long; flowers 3 cm. long, described as yellow, certainly very pale and nearly white; scales on 

 the flower-tube woolly and setose in their axils. 



Type locality: Not cited. 



Distribution: Andes of Chile. 



Echinocactus hankeanus Forster (Handb. Cact. ed. 2. 471. 1885), referred here as a 

 synonym by Schumann, was never described but first appeared as a synonym of Echino- 

 cactus humilis. The two varieties of Echinocactus ebenacanthus, minor and intermcdius, 

 were proposed by Labouret (Monogr. Cact. 254. 1853). To the former he referred as a 

 synonym Echinocactus ebenacanthus affinis Cels.

DESCRIBED SPECIES, PERHAPS REFERABLE TO THIS GENUS. 



Echinocactus castaneoides Cels in Salm-Dyck, Cact. Hort. Dyck. 1849. 165. 1850. 



Simple, globose to short-columnar; ribs 15 to 20, tuberculate, light green; radial spines 18 to 20, 

 acicular ; central spines 6, larger than the radials ; flowers very narrow, tubular. 



Type locality: Not cited. 



Distribution: Chile or Bolivia. 



Schumann first placed this species near Echinocactus acutissimus and later referred 

 it to a different section, placing it next to Echinocactus clavatus. He also says that it 

 comes from Copiapo, Chile. 



Mr. Sohrens sent a plant to Schumann, who called it Echinocactus castaneoides, but 

 it was probably E. acutissimus. 



Echinocactus kunzei* Forster, Handb. Cact. 293. 1846. 



Spherical, sunken at top; ribs 16 to 21; spines bent upward, when young yellow, in age gray ; 

 radial spines 9 to 12; central spines 2 to 4, a little longer than the radials, 2.5 cm. long; flowers 

 described as lateral, 6 to 8, 5.5 to 6 cm. long; scales of the ovary and flower-tube woolly and setose 

 in their axils. 



"Originally spelled kunzii.
