Dextropinnum herbaceum, the Right-Hander

The Right-Hander, or Dextropinnum herbaceum, is so named because each leaf is pinnate while all of the pinnae are on only the right side of each leaf. All species of Dextropinnum show this same morphology.

These plants have genetic affinities to Pinnatidendron, but never grow as large as that plant. Each leaf is accompanied by a slender inconspicuous inflorescence. As the plant matures, it produces a creeping rhizome that grows along the surface of the ground.

In the illustration above, the overall habit of the plant is shown, as well as rhizome detail and inflorescence detail.
