TABLE 3. Comparison among different species concepts of Eriosyce kunzei (C.F.Först.) Katt. 1 Zoll (Saxony) = 2.36 cm; 1 Lin. = 1/12 saxonian Zoll = 1.96 mm.

	Pyrrhocactus kunzei	Echinocactus kunzei	Eriosyce kunzei
Material	Ritter refers Echinocactus kunzei to	Förster: Type not extant nor illustrated.	Kattermann refers Echinocactus kunzei to the
	the plants from the vicinity of Copiapó	“Chile” as distribution	plants from the vicinity of the Elqui Valley,

	Valley (Vergara 2011).		2. “It never snows in the Sierra Hornillos”
	2. Ritter gave six locations: not only
	“Sierra Hornillos”; the town Paipote
	located in high mountains east of
	Copiapó is one of the six (Eggli et al.
	(1995) and Hunt (2003)
Stems	Subglobose (0.7 – 12 cm in diameter) to	Globose, somewhat appressed; 4 Zoll high	“10 (– 20) x 13 – 14 cm, somewhat
	slightly elongating with age	(= 9.4 cm); 5-5 ½ Zoll (11.8-12.98 cm) in	elongating with age)”
		diameter	This description is not correct. The plants

			(1989) under Neoporteria eriosyzoides:
			“30 – 40 cm”, and Lam. 56. Ritter under
			Pyrrhocactus eriosyzoides (F.Ritter)
			F.Ritter: “globose, later elongating” Another

			from the upper Elqui Valley are oval: F.Ritter
			(1980: 937, Pyrrhocactus eriosyzoides from
			upper Elqui Valley: “Areoles 7 – 10 mm
			long and 3 – 5 mm wide” (= oval). Hunt et
			al. (2006: Fig. 300.2, Eriosyce eriosyzoides)

			long and 3 mm wide (= oval); Hoffmann
			(1998: Lam. 56: Neoporteria eriosyzoides)
			shows clearly oval-shaped areoles;
			Kattermann (1994: Plate 9.3) shows oval-
			shaped and not extremely long and narrow
			areoles.
Spines	New ones grey-brown, with darker tips,	Brown, ash-grey with age	“First yellowish, later ash grey”.
	later turning grey		This description is not correct. Hoffmann
			(1998: Lam. 56: Neoporteria eriosyzoides)
