[3] Flower- and leaf-bearing stems grow off an unusual woody, aerial rhizome that is stiff, upright and linear or forked.

Leaf blades are hairless, egg- to lance-shaped with pointed tips and rounded bases with flat (not undulating) edges.

About 5 to 15 spreading to ascending side branches are set at 3-10 mm intervals along the main axis of the panicle.

Flowers are set on pedicels that are 2-5 mm long, ribbed and hairless.

[1] This is a species endemic to Costa Rica, documented in the provinces of San José and Cartago.
