 hidden by the spines, which are in two series, the outer filiform, 

 closely set, spreading, the others fewer, erect, yellowish. Mexico, 

 Ac., 1835. A distinct species, the whole surface of which appears 

 as if covered with a fine cobweb.

 columnar ; tubercles four-angled or ovate, bearing four small

 long, glaucous-green, furnished with a crown of yellow spines. 

 Mexico, 1835. A pretty little species, having a neat and sym- 

 metrical habit.

 borne at the summit of the plant ; base (calyx) of green scales, 

 tipped with red ; petals glossy straw-colour, numerous, serrated 

 and mucronate at apex, the more exterior ones entire, and tinged

 yellow. June. Stem columnar, glaucous green, 1ft. high ;

FIG. 508. MAMMILLARIA DOLICHOCENTRA 



M. dolichocentra (long-spurred).* /. pale rose or reddish-crim- 

 son. Stem stout, 6in. to Sin. high, Sin. in diameter ; tubercles 

 conical, narrow, iin. long, crowned with a small tuft of white 

 down, and a few white spines of irregular length. Mexico. A 

 strong-growing species, of variable habit. See Fig. 508. 



M. floribunda (copious-flowering). fl. pink, tinged with red, 

 very copiously produced ; petals very unequal. Stein globose- 

 sub-cylindrical ; tubercles thick, conico-hemispherical, obtuse ; 

 prickles villose-tomentose. Chili. This species approaches 

 M. atrata, but differs in its stouter habit, larger tubercles and 

 flowers, and unequal petals. (B. M. 3647.)

 of the prettiest of the dwarf -growing species. 



w, rather large. Stem cylin- 

 iameter ; tubercles small, green ; 



MAMMILLARIA HAAGEANA. 



M. Haagcana (Haage's). /. bright carmine-rose, scarcely longer 

 than the tubercles. May to July. Stem bullet-shaped when 

 young, somewhat clnb-shaped when old, only slightly woolly 

 in the axils; spines, outer ones about twenty, short, white; 

 central ones two, stiff, longer, black. Mexico, 1835. See Fig. 

 509 for which we are indebted to Herr FT. Ad. Haage, jun., of 

 Erfurt. 



BE. Lehmanni (Lehmann's). fl. moderately large, terminal ; 

 petals straw-colour, numerous, linear-oblong, imbricated ; fila- 

 ments red. Stem 6in. high, oblong-cylindrical, covered all over 

 with large conical tubercles, tipped with a minute woolly tuft, 

 from which springs a fascicle of seven or eight slender spines, one 

 of which is twice as long as the rest. Mexico, 1836. (B. M. 

 3634.) 



M. mlcromerls (small-flowered), fl. pale rose, very minute, 

 succeeded by red berries 4in. long. Stem resembling a flattened 

 ball, 2in. in diameter, and liin. hi~h, with a circulartuft of down 



, 



in the centre at the apex, about iin. across, surrounded by stiff 

 white spines ; tubercles very small, closely set Mexico, &c. 



BE. multiceps (many -branched). /. pale yellow, with a reddish 

 line in the centre of the petals. Stem dwarf, much-branched 

 or divided, lin. high, iin. in diameter; tubercles iin. to Jin. 

 long, fine, numerous, the inner yellow, larger, and stronger. 

 Mexico. 



M. TTniria.'fitfaini. (Neumann's), fl. of a rosy hue. Stem cylin-

 close and fine, the inner tawny, iin. to |in. long. Mexico. A very 

 attractive and neat plant. 



M. Parkinson!! (Parkinson's), fl. yellow. Stem 4in. to 6in.

 in beauty only about two hours. Stem conical or nearly globular, 

 3in. high, and 2iin. in diameter ; tubercles short and stout, each 

 crowned with a rosette, about iin. across, of white spines in one 

 series. Limestone hills on the borders of Mexico. One of the 

 handsomest species. 



M. phymatothele (tumour-nippled). fl. bright rose. Stem 5in. 

 to 6in. high, 2in. in diameter ; tubercles Jin. long, conical, dark 

 green, crowned with a small tuft of white down, and a few white 

 hair-like spines, which are spreading and erect. Mexico, 1846. 

 A not uncommon and strong-growing species. 



BE. pulchra (handsome), fl. rosy, rather large, produced near the 

 summit of the plant, from the woolly axils of the tubercles. 

 June. Stem green, 4in. to 5in. high, oblong-cylindrical, with a 

 depressed woolly apex, and almost covered with unequal spines, 

 arranged in eleven to thirteen symmetrical, very spiral lows ; 

 tubercles rather large, ovately pyramidal. Mexico, 1826. (B. B.

BE. pusilla (small).* fl. yellowish, the petals with a central line 

 of rose. Stem lin. to 2in. high, cylindrical-globular; tubercles
