  • Eulophia streptopetala by Duncan McFarlane

 

Description

Robust terrestrial with flowering stems that can grow up to 2.5m tall. The pseudobulb grows partially above the ground (much like a Cymbidium) and is up to 40 mm in diameter. The new growths develop from the base of the previous seasons matured pseudobulbs and the leaves are partially to fully developed when flowering. Leaves number between 4 and 9 and have a distinct ribbing appearance. The inflorescences, which grow next to the new growth with the developing pseudobulb, carries between 10 and 40 flowers. These are borne sequentially. Sepals are olive-green to green and are suffused with a reddish-brown. The petals are a chrome-yellow colour. No fragrance has been detected. The spur is 2mm in length.
