Cymbidium × fugongense S.Ke, S.R.Lan & Z.J.Liu, hybr. nat. nov (ṱḡėàƀ) ( Figs 3 , 4 )

Type:— CHINA. Yunnan Province: Fugong County (ĠÑfl), elevation 2000 m, rocks along valleys. 17 April 2022, Ke F002 (holotype: FAFU!) .

Cymbidium × fugongense is a natural hybrid of C. eburneum or C. maguanense and C. wenshanense , which is like the former in floral morphology, but differs in many ways. It has white-pink sepals and petals, the latter with purple-red central patches and are mottled. The midlobe of the lip is purple-red with a occasionally purple-red mottling on the base and apex of side lobes. The column is purple-red and mottled ventrally. It is like C. wenshanense in the lip base, which is fused to the basal margins of the column but otherwise differs in its floral morphology.

Epiphytic herbs with nearly fusiform or ovoid pseudobulbs, bilaterally flattened, 3.0–6.0 × 2.0–3.0 cm, enclosed in persistent leaf bases, new pseudobulbs produced every two or three years. Leaves 5–16, lorate, 30.0–50.0 × 1.2– 1.4 cm, apex bilobed with a minute mucro in the sinus, base distichous-equitant with brown membranous margins, 1.0– 1.5 mm wide, abscission zone 4–6 cm from base. Inflorescence arising from leaf axil, suberect, 20–30 cm long, inflorescence with 2 flowers, floral bracts triangular, 0.5–1.5 cm long, pedicel and ovary 2.5–3.5 cm long; flowers fragrant; sepals and petals white-pink, petals with purple-red central patch, mottled, lip white, midlobe purple-red with occasionally purple-red mottling on the base and apex of side lobes, yellow lamellae on the disc, column white with purple-red mottling; dorsal sepal oblong-obovate, 6.0–6.5 × 1.3–1.7 cm, apex subobtuse; lateral sepals oblong-obovate, slightly falcate, 5.5–6.0 × 1.2–1.5 cm, apex often subobtuse; petals narrowly obovate, 5.0–5.5 × 1.3–1.5 cm, falcate, apex acute; lip nearly broadly elliptic in outline, slightly shorter than the petals, trilobed, base fused to the basal margins of the column for 3–4 mm; side lobes erect, clasping the column, minutely hairy; midlobe ovate-triangular, recurved, densely short-hairy below the middle and the rest minutely hairy, margins undulate; disc with 2 longitudinal inflated lamellae extending from base to near the base of the midlobe and confluent to form a subdeltoid callus apically, adaxial surface minutely papillose and hairy; column 3.5–4.5 cm long, narrowly winged, subglabrous; pollinia 2, cleft, subsquare; viscidium with filiform appendages on both basal sides.
