Intermediate between P. albiflora and P. yunnanensis . It differs from P. albiflora by the longer peduncle, light pink flower (not white), and erose lamellae (not long papillae) on the lip. It also differs from P. yunnanensis by the floral bract that is as long as ovary or slightly longer than ovary (not shorter than ovary) and erose (not entire) lamellae on the lip.

Type: — CHINA. Yunnan: Baoshan City, Longyang District, Yangliu Township , 2500 m, December 2014 (flowered in cultivation at Kunming Institute of Botany in April, 2015), W. Zhang & S. B Zhang ZW002 (holotype: KUN!) .

Herbs, lithophytic. Pseudobulb green or dark olive-green, conic-ovoid, 2–2.5 × 1–2 cm, 1-leaved. Leaf not developing at flowering, lanceolate to narrowly elliptic when mature, 15–25 × 3–4 cm, apex acuminate. Inflorescence erect; peduncle 8–10 cm, prolonged when fruit; floral bract 30–36 mm long, as long as ovary or slightly exceeding the ovary. Flower solitary, rarely two, light pink. Dorsal sepal lanceolate, 42–48 mm long, apex acute; lateral sepals 40–46 mm long, slightly wider than dorsal sepal. Petals oblanceolate, 45–50 mm long, narrower than dorsal sepal, apex acute; lip ovate, 40–48 × 25–32 mm, apical margin lacerate or denticulate; disk with 4 erose lamellae. Column 28–30 mm.

Phenology: —Flowering from April to May.

Etymology:—Named after the City of Baoshan where this taxon was discovered.

Distribution and habitat:—Known only from the type locality. This hybrid grows on humus-covered rocks along streams, mixed with one of its parents P. albiflora at an elevation of 2400–2600 m, where the other parent P. yunnanensis and an autumn flowering species P. praecox can be found within an area of ten square meter. This hybrid has also been raised artificially by Paul Cumbleton and registered at Royal Horticulture Society as “ Pleione Siamang ” in 2009.
