Inflorescences are terminal, straight, 7-9 cm, bear 1 flower. Pedicels are naked.
The flowers are small.

Petals oblong-lanceolate, 1.5-1.8 × 0.5-0.6 cm, bare, sharp at the apex, often enveloping the lip. The lip is marsupial, slightly compressed, 1.2-1.5 cm, tuberous on the front surface. Staminodynia is widely elliptical, oblong, about 6 × 4 mm.

Identification
The leaves of Cypripedium bardolphianum are smaller, sometimes burgundy at the edges and depart from the stem at a sharper angle than the leaves of Cypripedium forrestii . Cypripedium bardolphianum flowers tend to be slightly darker with reddish-brown hues, while Cypripedium forrestii has flowers that are more yellow in color. The staminode Cypripedium forrestii is usually brown with yellow spots, while the staminode Cypripedium bardolphianum is one-color, reddish-brown. The sepals of Cypripedium forrestii are longer and almost touch in front of the lip. The sepals of Cypripedium bardolphianum are painted in a dark brown tone without spots, and the sepals of Cypripedium forrestii are yellow, honey-colored with characteristic brown spots. A significant difference is the hair comb on the sepals of Cypripedium forrestii ; the sepals of Cypripedium bardolphianum do not have it [5] .
In Culture
Cyp. bardolphianum is present in some private collections. Information about agricultural technology is contradictory.
soil pH is 7.6 [7] . Recommended protection from winter rains, and abundant watering in spring and early summer [8] .
