1^6 THE CACTACEAE. 



Mammillaria coronaria Haworth, Rev. PI. Succ. 69. 1 821, as to name. 



Cactus coronalus Willdenow, Enum. PI. 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 N eomammillaria. 



Cactus coronariiis Willdenow, given by Haworth as a synonym of MammiUaria 

 coronaria, is a mistake for C. coronatus. 



The variety Mammillaria coronaria minor was briefly described by Fbrster (Handb. 

 Cact. 212. 1846). 



Mammillaria Fulvispina Haworth, Phil. Mag. 7: 108. 1830. 



Cactus fulvispinus Kuntze, Rev. Gen. PL i: 260. 1891. 



Mammillaria rhodantha fuhispina Schelle, Handb. Kakteenk. 257. 1907. 



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 IMexican specimen which has led 

 to its being referred by later writers to M. rhodantha. The varieties ^17. fidvispina media 

 and M. fuhispina 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 Ncomam- 

 miliaria. 



The illustration (figure 184a) at the bottom of this page is of Ncomammillaria milleri 

 described on page 156.
