NEOMAMMILLARIAS 
The genus Neomammillaria is noted for the intricate designs 
shown in the spine arrangements of almost all its species. They re¬ 
mind one of pictures of enlarged snow ilakee. They grow from Ne¬ 
vada, U. S. A. to Northern South America. Many very fine ones grow 
in Mexico. 
N. compressa—Central Mexico. Individual plants very nice, clumps 
handsome. Plant pale bluish green; axils of tubercles white- 
woolly, setose; principal spines 4, lower much longer. Flower 
pink. A variable species but does well in cultivation. 
Obregonia denegri—South Central Mexico. A monotypic, short, glob¬ 
ular, of regular formation. Has small well defined spines, small 
white flowers from center. 
N. plumosa—North central Mexico. Individual plants small but grow 
into dense clusters, entirely covered by white plumose spines. 
Flowers white, red lined. A rare species, a gem among plants. 
Echinocereus delaeti—Mexico. Completely hidden by long white, 
curled hairs. Stiff reddish bristles help to distinguish this from 
small specimens of Cephalocereus senilis. 
N. schiedeana—Mexico. Axils of tubercles bear long bristle like hairs. 
Radiating golden spines on tips of tubercles star-like. Blossoms 
as seedling one to two years old. Good in cultivation. 
N. multiceps—Texas, Mexico. Miniature clumping species, hairy. 
Varies from gray, yellow to reddish brown. Flowers yellow-sal¬ 
mon, fruit red. 
N. Candida—Mexico. Found as individuals and clumps. Plants hidden 
by close white or rose spines, depending on variety. Flowers rose. 
Seedlings attractive. Good species in cultivation. 
Neomammillaria sp.—Victoria, Mexico. Most attractive species. Tub¬ 
ercles dark green, soft white wool all around them. Flowers dark 
rose. 
Neomammillaria sp.—Saltillo. More compact, short tubercled. Flow¬ 
er rose. j

from a central root, spreading or pendent from rocks. Aereoles,

viperina, stella aurata and rufocrocea. 
Neomammillaria microcarpa—West Texas to Arizona, Northern 
Mexico. Light spines with dark, hooked tips. Flowers rose-purple. 
N. carnea—Central and Southern Mexico. Plants cylindric, soli¬ 
tary or clustering. Tubercles 4 angled, milky, axils woolly; spines 4, 
lower the longest, Flower light pink. Illustrated page 30. 
NEMATODES. 
Plant collectors must always be on the watch for nematodes on 
the roots of their plants. Inspect new plants as received, and others 
as time arrives to transplant or when suspicion arises that they are 
not in the best of health or are not making the progress they should. 
Nematodes form as round nodules along the roots and indicate 1 
the root knot disease which will eventually sap the life of the plant 
attacked. If they are found cut off roots at base of plant, wrap them 
in paper and burn. Wash base of plant with rubbing alcohol and re¬ 
root after several days in fresh dry soil. Boil the pot and burn the 
infected soil.
