Dendrobium Smilliae Description
Plant Size and Type
Usually about 31 in. (80 cm) tall. Plants are normally robust, sympodial epiphytes that may be as small as 6 in. (15 cm) or as large as 118 in. (300 cm).
31 in. (80 cm) long. The stems are canelike. Nodes are more widely spaced at the base than at the apex.
The papery leaves are up to 6-7 in. (15-18 cm) long and quickly deciduous. They are lance-shaped to ovate with a pointed tip.
5 in. (13 cm) long. Racemes are densely flowered along their entire length. They arise from leafless stems.
Many per inflorescence. The nearly tubular flowers are 0.6-0.8 in. (1.5-2.0 cm) long and may remain somewhat closed. The waxy sepals and petals are yellow to greenish yellow with a rose suffusion and green or pink tips. The sepals are obliquely ovate. Petals are obovate-oblong. The fleshy lip, which is not lobed, is decorated with 2 raised lines. It is more intensely colored with bright green at the tip. The spur is purple.
Northeast Australia from the Burdekin River to the tip of the Cape York Peninsula, the islands of the Torres Straits, and across all of New Guinea. In Australia, plants are found from near sea level to 1950 ft. (0-600 m). They usually grow in lowland areas, but they are also plentiful in the lower mountains. The most common habitat is open forest near the edge of rainforests. Plants grow on tree trunks, tree ferns, rocks, and on hollow limbs or tree forks where bark and leaves have accumulated and composted to form a coarse soil. In New Guinea, plants grow on swamp trees, rocky outcrops, and rock faces in lowland forests and old plantations.
