Callista fimbriata (Hooker) Kuntze; C. oculata (Hooker) Kuntze; Dendrobium fimbriatum var. oculatum Hooker; D. paxtonii Paxton.
Stems rigid, decumbent or pendulous, cylindric or sometimes slightly fusiform above base, 50-100 cm, stout, 8-12(-20) mm in diam., unbranched, with many nodes, internodes 3.5-4.8 cm, longitudinally grooved, pale yellow or pale yellowish brown when dry. Leaves oblong or oblong-lanceolate, 8-15.5 × 2-3.6 cm, leathery, with tightly clasping leathery sheaths at base, apex acute, sometimes slightly bilobed. Inflorescences racemose, 5-15 cm, laxly 6-12-flowered; peduncle 2-4 cm; rachis thin, ± curved; basal sheaths several, overlapping, tubular, basal one shortest, ca. 3 mm, terminal ones to 10 mm, membranous; floral bracts ovate-triangular, 3-5 mm, membranous, apex acute. Pedicel and ovary pale green, 2.5-3 cm. Flowers slightly fragrant, spreading, thinly textured; sepals and petals golden yellow, lip a deeper hue, with purplish red stripes on either side at base, disk with a lunate transverse deep purple marking. Dorsal sepal oblong, 13-18 × 6-8(or more) mm, 5-veined, margin entire, apex obtuse; lateral sepals ovate-lanceolate, ca. as long as dorsal sepal and slightly narrower, 5-veined, base oblique, margin entire, apex obtuse; mentum rotund, ca. 3 mm. Petals oblong-elliptic, 12-19 × 7-10(or more) mm, 5-veined, margin slightly erose, apex obtuse; lip suborbicular, 15-20 mm, adaxially densely pubescent, base narrowed into a claw ca. 3 mm, margin compound fimbriate. Column ca. 2 mm, foot ca. 4 mm; anther cap conic, glabrous, front margin denticulate.
