Morphology

This botanical variety typically forms a medium to large tree with a spreading crown and milky latex. Unlike the nominate variety, the leaf margins of Maclura tinctoria var. subintegerrima are characteristically subentire or almost completely smooth, showing little to no serration. The leaves are arranged alternately along the branches and have a lanceolate to ovate shape.

The reproductive features include:

  • Dioecious nature: Male and female flowers develop on separate trees.
  • Male inflorescences: Cylindrical catkin-like spikes containing numerous small, yellowish flowers.
  • Female inflorescences: Globose heads that mature into small, fleshy compound fruits.

Applications

The wood of this tree is highly prized for its durability and heavy density. It yields a natural yellow pigment historically used in textile dyeing processes. Traditional timber operations also utilize the wood for construction and fence posts due to its resistance to rot.

Interesting facts

Botanical records suggest that the variety name subintegerrima directly highlights its nearly smooth leaf margins. The latex of the tree contains bioactive compounds that have been studied for potential antimicrobial properties. Birds and small mammals frequently consume the sweet, ripe syncarp fruits, aiding in seed dispersal.
