NEOM AMMILL ARl A . 



i6i 



delicately fragrant, i 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 Rio 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.

 or less; central spines 4, elongated, a little spreading, those toward the top of plant erect, 2 cm.

Fig. I 79a. — Neoraainmillaria 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 

 page 50). 



Illustration: Monatsschr. Kakteenk. 20: 151, as Mammillaria bombycina. 



Plate XV, figure i, 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. 



143. Neomammillaria occidentalis sp. nov. 



Cespitose, the branches slender, cylindric, 10 cm. high, densely spiny; radial spines about 12, 

 yellowish, spreading; central spines 4 or 5, reddish or brown, one of them longer and hooked; 

 flowers small, i cm. long, pink; stigma-lobes 9, slender; fruit said to be red. 



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

 1053, type) and again from the same locality by Stephen E. Aguirre, American Vice- 

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