NEOMAMMILLARIA. 



95 



The plant is named for Federico Eichlam (1862-1911), an enthusiastic cactus collector 

 who made very valuable discoveries in Guatemala. He published a cactus list in 191 1 

 (Kakteen-Verzeichnis Abgeschlosen Bnde 19 10).

Fig. 92. — Neomammillaria karwinskiana. 



Globose to cylindric, somewhat flattened above; tubercles terete, yielding milk when pricked; 

 axils very woolly and with long conspicuous white or brown-tipped bristles, much longer than the 

 tubercles ; spines 4, 5, or 6, all radial, sometimes one nearer the center than the others, nearly equal, 

 short, brown or blackish at the tips or throughout; flowers nearly 2 cm. long, the scales and outer 

 perianth-segments narrow, reddish except at the margins, ciliate; inner perianth-segments broader, 

 cream-colored, not ciliate, mucronate-tipped ; stamens cream-colored, much shorter than the inner 

 perianth-segments; style a little longer than the stamens; stigma-lobes 5, cream-colored; fruit 15 

 mm. long, red; seeds brown. 



Type locality: Mexico. 



Distribution: Oaxaca, Mexico. 



This species is near Neomammillaria mystax but the spines are usually radial, short, and 

 nearly equal. Specimens sent to Washington in 19 18 had some of the lowermost spines 

 much elongated and curved backward, .sometimes 2.5 cm. long. 



The plant flowers readily in cultivation. Professor C. Conzatti has repeatedly sent 

 it to us from Oaxaca.
