other respects it quite accords with our specimens. When 

 well grown the form is almost globose. It flowers copiously, 

 in July, from the summit, and numerous offsets are produc- 

 ed also from the apex, by which the plant may be easily 

 increased. 



Descr. Plant about six inches high, and almost the same 

 in breadth, of a rounded form, but nearly straight at the 

 sides so as to be somewhat cylindrical. Mammilla large, 

 nearly an inch broad at the base, hemispherical, but broader 

 than long, and obscurely two-lobed, dark green, slightly 

 glaucous : the axilla, especially the upper ones, where they 

 are less crowded, filled with dense, white wool. Spines 

 12 — 16, woolly at the base, spreading and recurved, pale 

 brown. Flowers five or six, opening at a time, on the top 

 of the plant, and making a handsome appearance when 

 spreading under the influence of the sun, of a deep sulphur 

 yellow colour, two and a half or three inches in diameter. 

 Petals linear-oblong, acuminated, serrated. Anthers orange- 

 coloured. Stigmas yellow.
