154 THE CACTACEAE. 
This species is very rare in living collections and in herbaria. When found in the field it 
is often associated with Mammiullaria graham1i and Coryphantha aggregata, which has led to 
the suggestion that it might be a hybrid between these species. 
The plant is named for General Timothy E. Wilcox, U. S. A., who collected exten- 
sively in Arizona, Oklahoma, Washington, and Alaska.

129. Neomammillaria mainae (K. Brandegee). 
Mammillaria mainae K. Brandegee, Zoe 5: 31. 1900. 
Globose or somewhat depressed, 5 to 8 cm. broad; tubercles pale green, naked in their axils; 
spines all puberulent, at least when young; radial spines about 10, widely spreading, yellowish or 
white except the brownish tips; central spines usually stout, yellowish except the strongly hooked 
tip; flowers from upper part of plant but in old axils, about 2 cm. long, with a broad open throat; 
outer perianth-segments with a brownish stripe, inner ones with a reddish central stripe with broad 
nearly white margins; acute inner perianth-segments more or less spreading; stamens purplish; 
style also purplish, stout, much longer than stamens; stigma-lobes 5 or 6, purplish, elongated, linear; 
fruit red, globose to obovate, not projecting beyond the tubercles; seeds dull black, obovate, 1 mm. 
long, punctate, with a narrow basal hilum. 
Type locality: South of Nogales, Sonora, Mexico. 
Distribution: Northern Sonora. 
For a long time it was known only from material collected by Mrs. F. M. Main, near 
Nogales, Mexico. It has been offered in the trade under the name of Mammillaria 
galeotti, to which, according to Mrs. K- Brandegee, it is not at all related. It was observed 
by Rose, Standley, and Russell in two localities near Hermosillo, Sonora, Mexico, and 
living plants were sent to Washington, which flowered in August 1910. This is not very 
close to any of the other species. It was collected again 
in Sonora by C. R. Orcutt in 1922.

130. Neomammillaria boedekeriana (Quhel). 
Mammillaria boedekeriana Quehl, Monatsschr; Kakteenk. 20: 
108. “1910. 
Globose to ovoid, but in collections becoming cylindric, 
dull green; tubercles cylindric; radial spines about 20, white; 
central spines 3, brownish black, one hooked; axils naked; 
flowers white with brownish stripes. 
Type locality: Not cited. 
Distribution: Doubtless Mexico, but range unknown. 
This plant, which was for a long time in cultivation 
in Europe, has, according to Mr. Bédeker, entirely dis- 
appeared. He writes that it is a prolific bloomer and that 
once he had a plant with 32 flowers open at the same time. Fic. 172a.—Neomammillaria boedekeriana. 
The species is named for Friederich Bédeker of Cologne, 
Germany. Quehl groups this species next to Mammillaria wrightit.

by Bédeker. The photograph was sent to us in 1923.
