they are all still nomen nudum. Mammillaria asteriflora Cels, M. binops Haage, M. cantera 
Haage, M. citrina Scheidweiler, VM. contacta Wendland, M. coryphides Forbes, M. crinigera

M. pyrrhacantha pallida Pfeiffer, M. salmiana Fennel, M. stephani Hortus, M. suberecta 
Pfeiffer, and M. villosa Fennel. ; 
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: Mammullaria 
cunetflora Hitchen, M. cylindraca Hitchen, M. divaricata, M. 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 longis pina, de grandii, deleuili 
Rebut, desertorum, donkelaari, dubia Hildmann, fulvolanata, geminiflora, glabrescens, 
goeringii, grusonii similis, guebwilleriana Haage jr., hermantiana Monville, hevernickii 
Senke, lapaixi Rebut, microdasys, monothele, morini Rebut, multicolor, nickelsi, nigerrima, 
numina, polia Sieber, quehlii, rebuti, roii Rebut, roessingii Gruson, semilonia, simonis, 
tellii, vartimamma Ehrenberg, villa-lerdo, wegeneri cristata, and xanthts pina. 
Schumann, at the close of his treatment of the genus Mammullaria (Gesamtb. Kakteen 
599. 1898), lists 158 names which he had not been able to refer. Later, 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:
