Common Name The Lovely Dendrobium

Flower Size to 1" [to 2.5 cm]

Found in Myanmar, 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 a terminal, 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 the apex of the leafy cane for 2 to 3 months in the early winter

Water and fertilizer should be reduced in the fall and for the end of the winter reduce water even more and eliminate fertilizer until new growth appears in the spring.

There are 3 very similar species if only the flowers are looked at, D delacourii, D simondii and D venustum. They are easily separated when the plants are taken into account. D delacourtii is 4" [10 cm] and under and has a terminal inflorescence carrying flowers with a wide open lip that is not inrolled around the column. D simondii is a 4 to 12" [10 to 30 cm] plant with leaves broadest towards apex and slightly obliquely bilobulate apex and has an inflorescence that arises from the upper leaf axils and has flowers with the mid lobe of the lip that is open around the column. D venustum has a 12 to 18" [30 to 45 cm] stem and has narrowly oblong leaves and blooms on a terminal flowering inflorescence with the lip more closed around the column
