PI. i: 260. 1891. Globose to short-cylindric, glaucous, more or less depressed at apex but almost hidden by the many closely appressed spine-clusters; axils of tubercles and young spine-areoles densel}^ lanate but in age glabrate; radial spines about 20, white, short, appressed; central spines 2, much stouter and longer than the radials, sometimes i cm. long, the upper ones often erect, white below, brown or black at tip; flowers small, carmine; fruit clavate, red; seeds brown. Type locality: Mexico. Distribution: Central Mexico, especially on the pedregal about the City of Mexico. We have referred to this species a plant which is very common in the Valley of Mexico and which is known in collections as Mammillaria peacockii. The name, first used by Riimpler (Forster, Handb. Cact. ed. 2. 286. 1885), was given as a synonym of Mam- millaria dealbata. It was offered for sale by Grassner as M. elegans dealbata (Monatsschr. Kakteenk. February 1920). Illustration: Grassner, Haupt-Verz. Kakteen 1912: 23, as Mammillaria peacockii. Plate XII, figure 3, shows a plant from Mexico, sent to the New York Botanical Garden in 19II. Figure 111 is from a photograph of a plant sent by Dr. Reiche from the Valley of Mexico in 1922. ».--i^-fc.
