Type locality: Guatemala. Distribution: Guatemala. This plant we know only from the collection of F. Eichlam; living specimens were sent to Washington by him which soon afterward flowered, but these have since died. Eichlam wrote that the flowers were a brilliant red. The species was named for Federico Eichlam, who lived in Guatemala at the time of his death in 1911. Illustration: Contr. U. S. Nat. Herb. 16: pi. 79. Figure 205 is from a photograph of the type plant in flower. 6. CHIAPASIA gen. nov.
