THE CACTACEAE. 



We have followed previous authors in referring here M ammillaria Jennelii 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 191 2. 



Illustrations: PfeifFer, Abbild. Beschr. Cact. 2: pi. 8, as Mammillaria zephyranthiflora; 

 Schelle, Handb. Kakteenk. 254. f. 175, as Mammillaria zephyranthoides. 



Figure 177 is reproduced from the first illustration cited above. 



140. Neomammillaria carretii (Rebut). 



Mammillaria carretii 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 i, slender, chestnut-brown, hooked; flowers 2.5 cm. long; inner perianth- 

 segments white, streaked with rose; fruit and seeds unknown. 



Fig. 178. — Neomammillaria bombycina. 



Fig. 179. — Neomammillaria occidentalis. 



Type locality: Not cited. 



Distribution: 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 sajffordii but radial spines are yellow, flowers white 

 with a streak of rose, and probably larger throughout. 



Illustrations: Grassner, Haupt-Verz. Kakteen 1912: 18; 1914: 24, as Mammillaria 

 carretii. 



Figure 176 is reproduced from a photograph sent us by L. Quehl in 192 1. 



141. Neomammillaria jaliscana sp. nov. 



Cespitose, globose, 5 cm. in diameter, bright green; tubercles in 13 rows, 4 to 5 mm. high; 

 radial spines 30 or more, at right angles to the tubercles; central spines 4 to 6, reddish brown, 

 darker toward the tips, one of them strongly hooked; axils naked; flowers pinkish to purplish.
