. The Cactaceae : descriptions and illustrations of plants of the cactus family. . Fig. 31a.—Coryphantha pectinata. Fig. 31 ft.—Coryphantha echii 18. Coryphantha nickelsae (K. Brandegee). Mainmillaria nickelsae K. Brandegee, Zoe 5:31. 1900. Described as globular, densely cespitose, often 7 cm. high, pale green and glaucous; older plants becoming purplish; tubercles almost hidden by the overlapping spines, rather broad at bas2, low, not densely arranged; spines 14 to 16, all radial (a few forming a small fascicle at top of groove), slender, at first simply spreading but afterward bent back and interlaced with those of adjoining tubercles, 8 to 10 mm. long, at first yellowish at base with dark tips, but afterwards bleaching; flowers described as bright yellow, with a red center, 5 to 7 cm. broad; fruit nearly globular, 5 to 7 mm. long, green; seeds small, brown. Type locality: Mexico, southward from Laredo, Texas. Distribution: Northern Nuevo Leon, Mexico. Plants collected by Robert Runyon in March 1921, on Mount La Mitra, near Monterey, which we believe should be referred here, deserve some detailed description. They grow in clusters of 4 to 12. From the axils of the lower tubercles near the surface of the ground numerous young plants or buds originate; the young spines are pale yellow, with reddish-brown tips, in age some bleaching white, others brownish to nearly black throughout; many of the first areoles have only radial spines but old plants often have one central spine to 2 cm. long, from all the upper areoles; flowers large, light yellow; inner perianth-segments spreading, linear-lanceolate, acuminate; anthers bright yellow. Plate III, figure i, is from a photograph of the plant collected by Mr. Runyon, which was made at his home in Brownsville, Texas, September 15, 1921. Figure 32 is from a photograph of a specimen sent us by Dr. Richard E. Kunze in Please note that these images are extracted from scanned page images that may have been digitall
