their tips bearing tiny tufts of wool, and four small spines, 

 which fall away on the tubercles becoming ripe, leaving two 

 short, diverginfir) central spines. Near Zimapan, Mexico (at an 

 elevation of 5000ft.). See Fig. 38. 



M, sub-polyhedra (often many-sided), ./f. 

 arranged in a zone on the tops of the old 

 stems; sepals greenish-yellow; petals bright 

 red. May. ft: scarlet, lin. long, pear-shaped. 

 Stem simple (till it becomes old, when it 

 develops offsets at the base), bro.idly cylin- 

 drical. Sin. high, Sin. in diameter; tubercles 

 four-sided at base, prism-shaped, bearing 

 pads of white wool in the corners at the 

 base, and crowned with tufts of four to 

 seven spines, usually all radial, sometimes 

 one central. South Mexico. See Fig. 39. 



M. sulcolanata (woolly-grooved). /. bright 

 yellow, Poppy-scented, nearly 2in. across, 

 the spread of the petals suggesting Paris 

 Daisies. June to August, /r. glaucous- 

 greeu, egg-shaped. Stem simple when 

 young, proliferous at sides when old, the 

 young plants developing from the apices of 

 the tubercles, not iu the axils, as is usual; 

 tubercles nut-shaped, large, the bases sur- 

 rounded by white wool, the points bearing 

 eight to ten rigid, brown spines, all ra- 

 diating fniw a little pad of wool. South 



Mexico, 1856. 



See Fig. 40. 



M, vivipara (stem-sprouting). Jl. in the apex 

 of the stem, lUn. long and broad : petals 

 about thirty, 'bright purple, timbriated. 

 May and June. fr. pale gri-en, ^in. long. 



Fig. 55. Mammillatiia longimamma. 



purple just before fading, regular and spreading 

 as in the Oxeye Daisy. August. Stem about 4in. 

 high, naked at base, woody and wrinkled when 

 old ; tubercles as in M. loiigimamma, but with 

 long, curving, radial spines, like needles, often 

 2in. long, white orrose-tinted when young, almost 

 black when old. Mexico. Owing to the woody 

 nature of the rootstock, and the long, tap-like 

 habit of the stouter roots, this should be planted 

 in pans instead of pots. See Fig. 56. 



M. phcllosperma (corky-seeded). Stems sim- 

 ple, sometimes proliferous at the base, globose 

 when young, afterwards almost cylindrical or 

 pear-shaped, Sin. high, 2in. in diameter; tuber- 

 cles iin. long, arranged in twelve spiral rows, 

 iilightly woolly in the axils ; spines radiating in 

 two rows, about lifty on each tubercle, the three 

 or four central ones hooked at the tip or some- 

 times stniight, and almost black, while the re- 

 mainder are almost white. This plant has not 

 been known to flower under cultivation. 



M. Scbeerii (?icheer*s>. ft. terminal, erect, witb 

 several whorls of spreaditig, recurved petals, the 

 lower ones tinued crimson, the upper ones pale 

 yellow, fomuug a shallow cup 2in. across. Stem 

 Yin. high and 5in. in diameter at b;tso ; tubercles 

 lar^e, swollen, somewhat flattened, the apicea 

 crowned with about a dozen brown .spinf3. 

 Mexico. 



M. Scbelbasil (Schtlhas*). A white, with a line 

 of rose down each petal, Jin. across. Early 

 summer. Stem producing offsets freely at the 

 base, which grow into full-sized stems, antl de- 

 velop young ones till a compact cushion is 

 formed; tubercles closely aminged, cylindrical, 

 shining green, with fifteen to twenty radial, 

 white, hair-like spines, Jin. long, and three 

 inner, thicker ones, usually only one being 

 hooked. Mexico. See Fig. 37. 



M. aemperviva (ever-living). /. inconspicuous, 

 scantily developed near the outside of the top 

 of the stem. Stem pear-shaped. Sin. wide, the 

 top slightly depressed; tubercles conical, }in. 

 long, their bases set in a cushion of whitn wool.
