Echinofossulocactus coptonogonus Lemaire Lawrence in Loudon Gard Mag 17 317 1841

Echinocactus coptonogonus Lemaire, Cact. Aliq. Nov. 23. 1838. Echinocactus coptonogonus major Lemaire, Cact. Gen. Nov. Sp. 87. 1839. Echinofossulocactus coptonogonus major Lawrence in Loudon, Gard. Mag. 17: 317. 1841.

Simple or perhaps cespitose, globular or a little depressed, 7 to 10 cm. high, glaucous-green; ribs stout, 1.5 cm. high, 10 to 14, acute; areoles about 2 cm. apart, when young abundantly floc-cose, but in age naked; spines 3 to 5, stout, a little incurved, the longest 3 cm. long, flattened; flowers 3 cm. long, 4 cm. broad; inner perianth-segments numerous, linear-oblong, acute, purple with white margins; ovary brownish violet, bearing thin scales.

Type locality: Mexico.

Distribution: Mexico, near San Luis Potosí and Pachuca, according to Schumann; the plant found at the latter locality is probably to be referred elsewhere.

This species is very abundant about San Luis Potosí from which place we have received considerable material from Orcutt and Palmer. It does not do well in cultivation. Only one plant is now alive in our collection and this has never flowered.

Echinocactus interruptus Scheidweiler (Cact. Hort. Dyck. 1849. 29. 1850) was referred here but never published. It was also used by Pfeiffer (Enum. Cact. 65. 1837) as a synonym of E. exsculptus.

2. Echinofossulocactus hastatus (Hopffer).

Echinocactus hastatus Hopffer in Schumann, Gesamtb. Kakteen 376. 1898.

Simple, depressed-globose, so cm. high, 12 cm. in diameter; ribs 35, triangular in section, light green, somewhat crenate; radial spines or 6, very short, straight, yellow, the upper ones flattened, often 3 cm. long; central spine solitary, 4 cm. long, porrect; flowers white (the largest in this genus); fruit becoming dry; seeds obovate, 5.5 mm. long, brownish gray, shining, finely punctate.

Type locality: Mexico.

Distribution: Mexico, Hidalgo, north of Pachuca.

This species and its variety fulvispinus Allardt were only mentioned by Förster (Handb. Cact. 315. 1846). We know this species only from description.

3. Echinofossulocactus multicostatus (Hildmann).

Echinocactus multicostatus Hildmann in Mathsson, Gartenflora 39: 465. 1890.

Simple, usually globose, but sometimes depressed, 6 to 10 cm. in diameter; ribs 100 or more, very thin, wavy, each bearing only a few areoles; areoles pubescent when young; spines usually 6 to 9, divided into two classes, the 3 upper spines elongated, 4 to 8 cm. long, erect or ascending, flexible, rather thin but not very broad, yellowish to brownish; lower spines spreading, weak-subulate, 5 to 15 mm. long; flowers 2.5 cm. long; outer perianth-segments oblong, acuminate; inner perianth-segments oblong, acute or obtuse; scales on the flower-tube oblong, acuminate; scales on the ovary broadly ovate, acute to acuminate, very thin, more or less papery, early deciduous.

Type locality: Mexico.

Distribution: Eastern part of Mexico.

According to Schumann, this species was collected by Mathsson at Saltillo, Mexico, and this place is doubtless the type locality for the species. Here, fine specimens were collected by Dr. Edward Palmer in 1905 and by W. E. Safford in 1907, both in flower, so we are now able to describe the flowers.
