... then we've got those farmers down in Patagonia that we know now of since yesterday, who'er laughing at out hickory and keeping the secret all to themselves- the bastards.
Perhaps it's Curupay? It surpasses hickory in some measures:
Curupay
Janka Hardness: 3,630 lbf (16,150 N)
Modulus of Rupture: 28,010 lbf/in2 (193.2 MPa)
Elastic Modulus: 2,617,000 lbf/in2 (18.04 GPa)
Crushing Strength: 13,700 lbf/in2 (94.4 MPa)

Shagbark Hickory
Janka Hardness: 1,880 lbf (8,360 N)
Modulus of Rupture: 20,200 lbf/in2 (139.3 MPa)
Elastic Modulus: 2,160,000 lbf/in2 (14.90 GPa)
Crushing Strength: 9,210 lbf/in2 (63.5 MPa)

Or perhaps it's "Guayabi"? It's said to be preferred to hickory for ax handles (in Paraguay, at least).
from
Consular Reports, 1896
Is "Guayabi" the same as "Guayabo", whose Modulus of Rupture, Modulus of Elasticity, and Work to Prop. Limit, all surpass that of Hickory, as shown in the table linked below:
