Figure 40 is a nearby view of a good-sized plant taken by P. H. Dorsett in northern Bahia, Brazil, in 1914. 12. Cephalocereus zehntneri sp. nov. Low, much branched, and spreading; branches 3 to 4 cm. in diameter, about 9-ribbed, more or less tubercled; areoles i to 2 cm. apart, long-hairy when young; spines often 30 or more, only slightly spreading, all acicular and bright yellow, the centrals similar to the radials or a little longer, the longer ones 3 to 4 cm. long; flowering areoles producing with the flowers long tufts of white wool; flowers slender, tubular, 6 to 7 cm. long, white to light cream-colored; inner perianth-segments oblong, obtuse; style slender, glabrous, cone-shaped at base; ovary naked. Collected by Leo Zehntner, from the Serra de Tiririca, Bahia, Brazil, November 1917. It is called chique-chique das pedras and is similar in habit to the one from Joazeiro described above. Dr. Zehntner says, however, that it prefers a rocky habitat while the common chique-chique is found on sandy ground and this statement is in accordance with ?ic Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carnegie Institution of Washington.
