"Size, habit, and number of ribs unknown : ribs tuberculate, with 

 areolae 10-15 mm. apart: spines at first variegated, dark and reddish, be- 

 coming more or less ashy-black ; radials 10 to 16, rigid, terete, radiant, 

 mostly uniform, 8 to 12 mm. long; centrals almost always 4, very stout and 

 prominent, 3 to 4 cm. long, cruciate, conspicuously angled and compress- 

 ed, sometimes twisted, the lowest usually the most flattened and sword- 

 like (2 to 3 mm. broad) : flowers red, 4 to 5 c m. long, with conspicuous 

 woolly and spine-bearing areolae over the ovary and lower part of the ca- 

 lyx : ripe fruit not seen. — Type in Herb. Brandegee, Lower California, El 

 Campo Allemand and San Gregorio. Specimens examined : Lower Cali- 

 fornia (Brandegee of 1889)."— Coulter, Cont. U S Na Hb iii, 389. (Ap. 1, 

 1896.) 



Orcutt, Review of the Cactaceae, i. 7. Jl. 3, 1897. 



Plant caespitose, often 2 feet or more across, consisting of many cyl- 

 indrical heads, mostly 6 or 8 inches high, i l / 2 to 2 inches in diameter, with 

 8 or 9 interrupted, strongly tuberculate, ribs. The young spines fre- 

 quently tinged with brilliant magenta, the older spines often of an ivory 

 white, with centrals of a deep magenta — making a very handsome appear- 

 ance. Abundant in the vicinity of the mines at Calmalli, and eastward 

 nearly to the shores of the Gulf of California. This has much the same 

 aspect as Cereus Engelmanni, with similar variations in the color of the 

 spines. 



Echinocactus Fordii Orcutt 



Orcutt, Review of the Cactaceae, 1:56. 



Globose, 6 inches or more in diameter, with about 18 tuberculated 

 narrow ribs closely set with clusters of stout ashy gray spines, 4 central, 

 annulated, the longest 1% inches long, and hooked; 2 slender spines above 

 with about 14 divergent radials ; flower an inch across, about 32 rose pur- 

 ple petals in 2 series, 9 greenish stigmata, style tinged with red, filaments 

 red at top an 1 yellow at base, anthers orange yellow. Near Lagoon Head, 

 Baja California. Named for Lyman M. Ford, of San Diego, who has 

 taken a great interest in cacti. Apparently the same plant was distribu- 

 ted in 1894, from near San Quintin bay, as a form of E. peninsulae.
