2. Echinofossulocactus hastatus (Hopffer). 
Echinocactus hastatus Hopffer in Schumann, Gesamtb. Kakteen 376. 1898. 
Simple, depressed-globose, 10 cm. high, 12 cm. in diameter; ribs 35, triangular in section, light 
green, somewhat crenate; radial spines 5 or 6, very short, straight, yellow, the upper ones flat- 
tened, often 3 cm. long; central spine solitary, 4 cm. long, porrect; flowers white (the largest in this 
genus) ; fruit becoming dry; seeds obovate, 1.5 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 Forster 
(Handb. Cact. 315. 1846). We know this species only from description. 
3. Echinofossulocactus multicostatus (Hildmann). 
2 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-subu- 
late, 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 col- 
lected 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. ;

4. Echinofossulocactus wippermannii (Miihlenpfordt). 
Echinocactus wippermannii Miiblenpfordt, Allg. Gartenz. 14: 370. 1846. 
+ . ° . . d 
Simple, obovoid, 15 cm. high, 5 to 6 cm. in diameter, dull green; ribs 35 to 40, compressed, 
slightly undulate; areoles 12 pak apart, hairy when young, glabrate in age; radial spines 18 to : 2, 
setaceous, white, 15 mm. long; central spines 3 or 4, erect, elongated, 2 to 5 cm. long, subulate, 
terete, blackish; flowers 1.5 mm. long, dull yellow. 
Type locality: Mexico. 
Distribution: Hidalgo, Mexico. 
We know this species only from description. Schumann states that both Ehrenberg 
and Mathsson collected it in the state of Hidalgo, but the species collected there by Dr. 
Rose, while of this relationship, is certainly distinct (Rose, No. 8717, in part). sa7),an 
Schumann refers here Echinocactus acifer spinosus Wegener (Linnaea 19: 35 5: a 47) 
unpublished variety, which is the same as Echinocactus spinosus Wegener (Al ig. Gar ene 
12: 66. 1844). This name is older, and if the same as E. wippermanni it woul 
replace it; E. acifer Hopffer (Forster, Handb. Cact. 520. 1846) is said to belong here accord- 
ing to Labouret. ; ;
