Echinofossulocactus lancifer Dietrich

Echinocactus lancifer Dietrich, Allg. Gartenz. 7: 134. 1839.

Echinocactus dietrichii Heynhold, Nom. 2: 92. 1846.

Nearly ovoid, somewhat depressed at apex; ribs numerous, strongly compressed, undulate; areoles few to each rib, when young tomentose; spines 8, white or brownish at apex; some of them broad and flat; flowers rather large, rose-colored; flower-tube described as long; perianth-segments linear-oblong, widely spreading.

Type locality: Mexico.

Distribution: Mexico.

Pfeiffer in 1837 attempted to identify Echinocactus obvallatus with certain plants then in the Schelhase collection, but later when he figured his plant he questioned this identification, although he did not rename it. Dietrich, however, in 1839, named the Echinocactus obvallatus Pfeiffer in part, as above.

Echinocactus lancifer was used by Reichenbach (in Terscheck, Suppl. Cact. 2), but whether properly described or not we do not know. The name was, however, formally published by Walpers in 1843 (Repert. Bot. 2: 320), but this date was after Dietrich had published his name. Heynhold evidently considered Reichenbach's name properly published for he changed Dietrich's name to Echinocactus dietrichii.

Illustration: Pfeiffer, Abbild. Beschr. Cact. 2: pl. 22 (fide Index Kewensis), as Echinocactus obvallatus.

Echinocactus gladiatus ruficeps Lemaire in Labouret, Monogr. Cact. 215. 1853.

Echinocactus gladiatus intermedius Lemaire in Labouret, Monogr. Cact. 215. 1853.

Plant glaucescent, ovoid to oblong, 12.5 cm. high, 10 cm. in diameter with a depressed apex covered with connivent spines; ribs prominent, rather broad, obtuse, 14 to 22; spines 10, gray, 4 upper spines subulate, of these 3 usually ascending, the central spreading or porrect, the largest 5 cm. long, 4 lower spines acicular; flowers and fruit unknown.

Type locality: Mexico.

Distribution: Probably eastern Mexico.

Schumann in his monograph does not take for this name the plant as originally described and figured by Link and Otto, but a later description used by Pfeiffer and adopted by Salm-Dyck. The original Echinocactus gladiatus, based on Deppe's plant, is very different from Schumann's plant.

The plant is known to us only from description and illustration. We are following Lawrence in including this little-known species in Echinofossulocactus, but we are very doubtful about its true relationship.
