 of main branches "20 ; of branchlets "10 to "12. A stouter branched 

 specimen is 10 inches high ; 10 broad ; diameter of tnmk '50 ; of main 

 branches -25 to 'So ; of branchlets "12 to '18 ; length of verrucie '06 ; 

 breadth 'OS. In some specimens many of the branchlets d© not ex- 

 ceed '08 in diameter. A specimen from Zorritos is 15 inches high ; 8 

 broad ; diameter of branchlets •12 to '18 ; many of the simple terminal
