Question: Which genus is in the verbena family, Citharexylum or Laelia?
Sentence (from "Citharexylum"): The generic name is derived from the Greek words κιθάρα ("kithara"), meaning "lyre", and ξύλον ("xylon"), meaning "wood," referring to the use of the wood in the sounding boards of string instruments. Several species, especially "C. caudatum" and "C. spinosum", are cultivated as ornamentals.
