Mammillarias, in common with other cacti, run into many forms. Some of these forms may be valuable to the horticulturist, and yet not sufficiently distinct to warrant the giving of definite botanical names. The following names, not accounted for in the above review, are offered in the catalogues of American dealers: M. Brandii.—M. brunea.—M. cirrhifera longispina (see No. 75).—M. Donatii.—M. filipendula.—M. fuscata Leona (see Nos. 35, 62).—M. lassomeri= M. Lesaunieri(?).—M. melonacantha is an uncertain garden name. —M. montana.—M. nicholsonii= Nickelsae(?).—M. Rebsamiana.—M. recurvens.—M. rigidispina.
The following species, mostly recently described, have appeared in foreign publications. None of them is being grown in Amer.: M. Boedekeriana, Quehl.—M. bombycina, Quehl.—M. camplotricha, E. Dams.—M. collina, Purpus.—M. cordigera, Heese.—M. Emskoetteriana. Quehl.—M. Joosensiana.. Quehl.—M Knippeliana, Quehl. —M. Mundtii, Schum.—M. napina, Purpus.—M. pilispina, Purpus. —M. ramosissima, Quehl.—M. Ruestii. Quehl.—M. Sartorii. Purpus.—M. Seideliana, Quehl.—M. trichacantha, Schum.—M. uniseta. Quehl.—M. Verhaertiana, Boedeker.
The following species are likely to appear in the trade at any time: M. ceratites, Quehl. This species has been associated with M. Delaetiana and M. durangensis, but it seems to be very close to M. conoidea. It has not yet been intro. into American trade.—M. Delaetiana, Quehl. Sts. club-shaped, about 3 in. high: tubercles grooved on the upper side: fla. large, pale yellow. Mex., sometimes credited to Calif.—M. durangensis Runge. Very beautiful species with small central fls. Does not grow well in cult.—M. pseudoperbella, Quehl. A species recently intro. into Eu. Very close to M. elegans. Not yet cult, in Amer.
