|Common Name(s): Guatemalan Mora, Mora|
Scientific Name: Possibly Inga spp. (almost universally mislabeled as Maclura tinctoria)
Tree Size: 60-80 ft (18-25 m) tall, 2-3 ft (.6-1.0 m) trunk diameter
Average Dried Weight: 57 lbs/ft3 (910 kg/m3)
Specific Gravity (Basic, 12% MC): .75, .91
Janka Hardness: 2,380 lbf (10,590 N)
Modulus of Rupture: 19,560 lbf/in2 (134.9 MPa)
Elastic Modulus: 2,160,000 lbf/in2 (14.90 GPa)
Crushing Strength: 11,710 lbf/in2 (80.8 MPa)

Color/Appearance: This Guatemalan variant of Argentine Osage Orange is sometimes called “Guatemalan Tigerwood” or “Mora” (not to be confused with Mora excelsa, which also goes by the common name of Mora) which is light to medium reddish brown, with streaks of lighter and darker material.
Grain/Texture: Has a straight to interlocked grain, with a fine to medium texture.
Endgrain: Diffuse-porous; medium pores in no specific arrangement; solitary, and commonly in radial multiples of 2-3; tyloses and other deposits common; growth rings may be distinct due to seemingly marginal parenchyma; rays visible without lens; parenchyma banded, paratracheal parenchyma vasicentric, aliform (lozenge and winged), and confluent.
Rot Resistance: Guatemalan Mora is very durable and has good weathering characteristics; it is also resistant to termites.
Workability: Working this wood can be difficult due to its hardness and density, though it is reported to have little dulling effect on cutting edges. It turns well, and also takes stains, glues and finishes well.
Odor: No characteristic odor.
Pricing/Availability: Guatemalan Mora should be moderately priced for an imported hardwood.
Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
Common Uses: Heavy construction (within the tree’s natural range), flooring, furniture, turnings, and other small specialty wood items.
Comments: Perhaps one of the most confusing names in modern hardwood commerce is the selling of a Guatemalan wood being marketed as “Mora” with a scientific name Maclura tinctoria—both the common and scientific names are incorrect. The common name Mora has traditionally been used for an unrelated wood found in northern South America (not found in Guatemala) known by the scientific name Mora excelsa. Also, the scientific name Maclura tinctoria belongs to an unrelated Argentine variety of Osage Orange (sometimes called Fustic) with a bright yellowish color when freshly cut, aging to a russet brown upon exposure to light. The exact species of Guatemalan Mora is not known, but is suspected to be an Inga species.
