176 THE CACTACEAE. 
MAMMILLARIA CORONARIA Haworth, Rev. Pl. Succ. 69. 1821, as to name. 
Cactus coronatus Willdenow, Enum. Pl. Hort. Berol. Suppl. 30. 1813. Not Lamarck, 1783. 
Judging from Willdenow’s original descriptions of this plant it is not of this genus. 
He says that it is 5 feet long and a foot in diameter and that the central spine of the areole 
is hooked. Its geographical origin was not recorded and its flowers were not described. It 
was grown at Berlin prior to 1813 and later at the Chelsea Garden, London. Descriptions 
of this species are based largely on Cactus cylindricus Ortega, a very different plant. 
Through the courtesy of N. E. Brown we have a photograph of Mammillaria 
coronaria from Haworth’s collection with the date “Feb. 20, 1846.” This photograph 
answers Haworth’s brief description and differs from Willdenow’s in having the spines 
all straight. Haworth’s plants we would refer to Neomammillaria. 
Cactus coronarius Willdenow, given by Haworth as a synonym of Mammillaria 
coronaria, is a mistake for C. coronatus. 
The variety Mammillaria coronaria minor was briefly described by Forster (Handb. 
Cact. 212. 1846). 
MAMMILLARIA FULVISPINA Haworth, Phil. Mag. 7: 108. 1830. 
Cactus fulvispinus Kuntze, Rev. Gen. Pl. 1: 260. 1891. 
Mammillaria rhodantha fulvispina Schelle, Handb. Kakteenk. 257. 19C7. 
This plant was said by Haworth to come from Brazil and if so it is to be excluded from 
this relationship. Pfeiffer associated the name with a Mexican specimen which has led 
to its being referred by later writers to M. rhodantha. ‘The varieties M. fulvispina media 
and M. fulvispina minor (Salm-Dyck, Cact. Hort. Dyck. 1844. 8. 1845) were not described. 
MAMMILLARIA PICTURATA Labouret, Rev. Hort. IV. 4:28. 1855. 
Simple, cylindric, 8 cm. high, 5 cm. in diameter; radial spines 20, white, setiform, 4 mm. long; 
central spines 6, yellowish; flowers and fruit unknown. 
Although Labouret stated that this plant came from Mendoza, Argentina, the Index 
Kewensis says Chile. If it is in southern South America, it does not belong to Neomam- 
millaria. 
The illustration (figure 184a) at the bottom of this page is of Neomammillaria milleri 
described on page 156.
