The following names appeared first, published by Forbes (Journ. Hort. Tour Germ. 

 147. 1837), but are so briefly described that they can not be identified: Mammillaria 

 cuneiftora Hitchen, M. cylindraca Hitchen, M. divaricata, A'l . flavescens Hitchen, M. grandis 

 Hitchen, M. lutescens, and M. pulcherrima. Some of these names were afterwards used, but 

 whether they were applied to the same plants we can not tell. 



The following names of Mammillaria listed by Haage (Cact. Kult. ed. 2. 1900) are 

 without description: brandtii Haage jr., bruennowii, celsiana longispina, de grandii, deleuili 

 Rebut, desertorum, donkelaari, dubia Hildmann, fulvolanata, geminiflora, glabrescens, 

 goeringii, grusonii simUis, guebwilleriana Haage jr., hermantiana Monville, hevernickii 

 Senke, lapaixi Rebut, microdasys, monothele, morini Rebut, multicolor, nickelsi, nigerrima, 

 numina, polia Sieber, qiiehlii, rehuti, roii Rebut, roessingii Gruson, semilonia, simonis, 

 tellii, variimamma Ehrenberg, villa-lerdo, wegeneri cristata, and xanthispina. 



Schumann, at the close of his treatment of the genus Mammillaria (Gesamtb. Kakteen 

 599. 1898), lists 158 names which he had not been able to refer. I^ater, Otto Kuntze 

 referred many of the names to the genus Cactus, thus making many useless synonyms. Some 

 of these names of Schumann we have been able to refer more or less definitely to other 

 species, but there still remain many which we can not place. Most of them were described 

 without flower and fruit, and since the types were not preserved it is doubtful if many more 

 can be ever identified. The residue is as follows :
