160 THE CACTACEAE. 
We have followed previous authors in referring here Mammullaria fennelit and Pfeiffer’s 
illustration, based on his statement that the type plant was abnormal and much smaller 
than the one figured and with smaller tubercles. 
The plant was in flower at Erfurt, Germany, where Dr. Rose studied it in 1912. 
Illustrations: Pfeiffer, Abbild. Beschr. Cact. 2: pl. 8, as Mammillaria zephyranthtflora,; 
Schelle, Handb. Kakteenk. 254. f. 175, as Mammillaria zephyranthotdes. 
Figure 177 is reproduced from the first illustration cited above. 
140. Neomammillaria carretii (Rebut). 
Mamumillaria carretit Rebut in Schumann, Gesamtb. Kakteen 542. 1898. 
Solitary, dull green, globose, depressed, small, 5 to 6 cm. in diameter; tubercles cylindric; axils 
of tubercles naked; radial spines 14, subulate, spreading, recurved, nearly clothing the plant, long, 
yellowish; central spine 1, slender, chestnut-brown, hooked; flowers 2.5 cm. long; inner perianth- 
segments white, streaked with rose; fruit and seeds unknown. 
Fic. 178.—Neomammillaria bombycina. Fic. 179.—Neomammiillaria occidentalis. 
Type locality: Not cited. 
Dstribution: Doubtless Mexico, but no definite locality known. 
We have not seen this species and know it only from descriptions and illustrations. 
__ It is related to Neomammillaria saffordii but radial spines are yellow, flowers white 
with a streak of rose, and probably larger throughout.
