NEOMAMMILLARIA. 161 
delicately fragrant, 1 cm. broad when fully expanded; outer segments ovate-oblong, acute or obtuse 
with a more or less serrulate margin; inner perianth-segments oblong, obtuse; filaments pinkish; 
stigma-lobes 3 or 4, white; fruit white, 8 mm. long; seeds black. 
Collected by J. N. Rose at Rfo Blanco, near Guadalajara, Mexico, in September 1903 
(No. 858, type), by C. R. Orcutt near Guadalajara and by B. P. Reko from the same locality 
in 1922 (No. 4410). 
Dr. Rose introduced this species into cultivation but his plants all died. It flowered 
with us in March 1904 and again in 1923.

Fic. 179a.—Neomammillaria occidentalis. 
Type locality: Mexico. 
Distribution: Mexico, but range unknown. 
We have had this plant in cultivation for a number of years. It is a very attractive 
plant, the top being covered by a mass of white hairs which come from the closely set young 
tubercles. _ 
_>Mammillaria cordigera Heese resembles this species very much in its spines and form, 
but is described as with grooved tubercles, which would exclude it from this genus (see 
age 50). 
ms tiiestration: Monatsschr. Kakteenk. 20: 151, as Mammillaria bombycina. 
Plate xv, figure 1, shows a plant received by Dr. Rose from M. de Laet in 1910 and 
probably from the type collection. Figure 178 is from a photograph of another plant 
from the same collection.

Collected by Dr. E. Palmer near Manzanillo, Colima, Mexico, December 1890 (No.

Consul-in-Charge, October 1922. Dr. Palmer's field notes say:
