Name: Dendrobium macrophyllum var. macrophyllum
Synonyms: Callista macrophylla (A.Rich.) Kuntze; Latourorchis macrophylla (A.Rich.) Brieger; Sayeria macrophylla(A.Rich.) Rauschert
Etymology: macrophyllum derives from the Greek words makros (large) and phyllon (leaf) and directly refers to this species’ strikingly large-leaved foliage.

First description: 1834 by Achille Richard (originally described as Liparis macrophylla, later transferred to the genus Dendrobium by John Lindley).
Origin / distribution:
Widely distributed in tropical Asia and the western Pacific (including Java, the Philippines, Sulawesi, New Guinea, the Solomon Islands, and Fiji).
Location / habitat:
Grows epiphytically in hot coastal rainforests as well as cooler montane cloud forests. The species colonizes tree trunks and branches at elevations from sea level to about 1,700 m, usually in partially shaded to bright locations with high humidity year-round.
Description & notes:

Dendrobium macrophyllum belongs to the section Latouria and is a robust, medium- to large-sized orchid. It produces sturdy, spindle- to club-shaped, thickened, furrowed pseudobulbs that bear 2 to 4 large, leathery, broadly elliptic leaves at the apex. The upright, many-flowered inflorescences emerge from the upper leaf axils. The long-lasting, waxy flowers give off a delicate fragrance. They are characterized by flowers up to 5 cm in diameter, whose sepal exteriors have a strikingly stiff-haired to warty texture. The base color varies from greenish yellow to creamy white, intensely marked with purple or brown spots and stripes on the lip.

In cultivation, this variety is relatively adaptable due to its wide elevational range and is generally grown under intermediate to warm conditions. As a member of the section Latouria, it does not require a strict, dry winter rest. The plant should be kept evenly moist throughout the year, allowing the substrate (medium-grade pine bark) to dry slightly between waterings. A bright to partially shaded location, humidity above 70%, and continuous air movement are essential for healthy growth.
