C.lanceolatumThe Guatemala Expedition of the scientist Paul C. Standley from 1938 to 1939 provides the most comprehensive description of C. lanceolatum and the habitats where plants of the species were found. The plant was very close to extinction (It actually was thought to be extinct) until the rediscovery of this species in 1991 more then 50 years later under the lead of Paul W. Bosland who organized another expedition to Guatemala. All of Standley described habitats were visited. A resettlement of C. lanceolatum could, after an investigation of the locations, not be established.
