THE CACTACEAE. 



Figures 35 and 36 are drawn from a co-type herbarium specimen collected by Charles 

 Wright in New Mexico, 1851-1852.

 Echinocadus chlorophthalmus Hooker in Curtis's Bot. Mag. 74: pi. 4373. 1S48. 

 Cespitose, nearly globose, glaucous-green; ribs 10 to 12, somewhat tuberculate ; areoles circular; 

 radial spines 7 to 10, slender, needle-like, 12 to 18 mm. long, spreading; central spine one, stouter 

 than the radials, the central as well as the radials pale brown but reddish at base when young; inner 

 perianth-segments spatulate, acute, somewhat serrate towards the tip, glossy above, purple, whitish 

 at base; stigma-lobes bright green; ovary and fruit spiny.

Fig. 38. Echinocereus knippelianus. 



Type locality: Real del Monte, Mexico. 



Distribution : Known only from the type locality. 



This species, although described as an Echinocadus, is undoubtedly an Echinocereus, 

 but it is not near Echinocereus conglomeratus as Schumann suggests. 



In 1905 Dr. Rose visited Real del Monte, the type locality, where he collected the 

 flowers of an Echinocereus (No. 8730) which correspond very well to the cited illustrations.

*The authority for this name was given as Carp or as an abbreviation, Carp., which suggested that it might be 

 an abbreviation for Carpenter, but as there was no cactus authority of this, name the explanation seemed unsatis- 

 factory. It was known that various short articles appeared in the Baltimore Cactus Journal under this name with 

 a California address. This led us to write to C. R. Orcutt and then to Ernest Braunton, both of whom have long 

 been in touch with horticultural interests in California. From them we obtained the following information: 



Carp's real name was Daniel R. Crane. At one time he was a dealer of cacti and advertised freely under the 

 name of the California Cactus Company, Soldiers' Home, Los Angeles County, California. His pen name, he 

 explained, was a reversal of the first syllable of practical, which is of doubtful significance. Crane served in the 

 Union Army and was somewhat erratic in his later years. He died about 1901. 



tThis reference is taken from Schumann (Gesamtb. Kakteen 252. 1897) who cites Carp as the authority for 

 this binomial. The original publication of E. liebnerianus does not refer to Carp but to Liebner. It occurs in the 

 following letter of K. Schumann to the editor of the Baltimore Cactus Journal (2: 262. 1896): 



"The cactus found by McDowell and pictured twice in the November number of the Baltimore Cactus Journal 

 is described in the November number of the Monatsschrift fur Kakteenkunde and named by Mr. C. Liebner, Echino- 

 cereus liebnerianus."
