Common Name The Lovely Dendrobium
Flower Size to 1" [to 2.5 cm]
Found in Burma, Thailand, Cambodia, Laos and Vietnam at elevations of 300 to 500 meters as a medium sized, hot to warm growing epiphyte with arching or pendulous stems carrying to 7, oblong or strap like, leathery, glossy, bright green leaves that blooms in the summer and early fall on an axillary or apical, arching to horizontally spreading, 6 to 12" [15 to 30 cm] long, few to many [5 to 25] flowered inflorescence that arises from the nodes near and along the apex of the leafed cane for 2 to 3 months in the early winter water and fertilizer should be reduced and for the end of the winter reduce water even more and eliminate fertilizer until new growth appears in the spring.
This species and D delacourii are very similar, but separated mostly on the length of the stem. If the plant is greater than 4" [10 cm] then it is D venustum, if less than 4" [10 cm] then it is D delacourii. D venustum is said to have longer cilia on the lip than D delacourii, I find that is not nessesarily so. I personally find the major difference to be the midlobe of D delacourii is not inrolled and in D venustum it is and encompasses the column more.
