Dr. Leslie Garay writes "The Dunsterville illustration under S. liliastrum is now Sob. elizabethae." (pers. comm. 1/2002)
In October 2001, we trekked to Venezuela's Gran Sabana in Bolivar State and observed thousands of medium-tall, blooming plants that we thought at first to be Sobralia liliastrum. The flowers were nearly identical to Dunsterville's line-drawings of that species. Plants grew to about 1.5 meters tall in open conditions on a rocky slope at 3000-4500 ft elevation, in a clean quartz sand amidst boulders. Image at right photographed by Nina Rach. Note the long, recurved sepals (7+ cm. long).
In 2003, Gustavo Romero Gonzalez revisted this complex of white sobralias found in the Venezuelan Guyana [elizabethae,
liliastrum] and published his thoughts in Harvard Papers in Botany.
