A curious cactoid plant, and really handsome of its kind, na- 

 tive of Brazil. Young individuals are of an oval form, but when 

 more fully grown attaining a height of a foot or a foot and a 

 half, quite clavate, furrowed for its whole length, the ridges 

 studded with white cottony pulvilli, from which radiate tufts of 

 long, white, setaceous bristles, mixed with about four, brown or 

 purple, moderately strong aculei. The flowers are very pretty.
