Arborescent, 20 feet high or more, as- 

 suming somewhat an umbrella form 

 from its manner of branching; joints 

 mostly short, thick; ribs 5 or 6, acute 

 when young, with sharply defined inter -

 bearirg large woolly spineless areolae; 

 stems of young growth 3 inches in diam- 

 e.er, are.Le iy 2 inch apart, wo lly— in 

 age the enlarged bulbous baes of the 

 spines are in close contact, covering the 

 areolae completely (or spineless !) ; radial 

 spines 3-5, X k-W 2 inches long, central spine 

 iy 2 inches in maximum length, straight 

 or twisted, all stout, angled, ashy black, 

 woody; central spine sometimes absent, 

 lateral radials usu lly tne longer, very 

 var.abie. Plant smooth, brigut apple

 lae bearing minute scales (more rarely 

 bearing in their axils a more minute 

 spine), purple (sometimes glaucous) with 

 purple puip: fruit bursting irregularly at 

 maturLy. As many as 14 rruits were seen 

 growing from one a eola; one rib of 11 

 areolae on a joint of 5 ribs bore 36 fruits, 

 only 1 of the aieolae without fruit, and 

 this is frequent on the hundreds of 

 branches — old and young alike, almost to 

 the trunk. Seeds l^rge. black, 63 from 

 one berry. Fruit ripening in June. 1902, 

 in the sate of Caxaci, Mexico (Orcutt
