In Cypripedium molle the lateral sepals are completely fused into one whole piece. With Cypripedium susanae it shares the caespitous habit, but it grows in pine and oak forest, the flowers are light yellow; the dorsal sepal is suborbicular-elliptic and ends in a short, triangular acumen, 2" [5 cm] long, 1.52" [3.8 cm] wide, with three main carinas and two supplementary on each side, submarginal; the lateral sepals have a suborbicular synsepal, with a short and broad apiculum with a tiny mucron in the breast, 1.6" [4 cm] long, 1.48" [3.7 cm] wide, with four carinas; shallowly concave petals, with recurved sides, the bottom, elliptical, obtuse, 2.4" [6 cm] long, 1.52" [3.8 cm] wide; the labellum in natural position is 1.96" [4.9 cm] long 1.42" [3.6 cm] wide and 1.04" [2.6 cm] deep, the base dressed with curly or woolly trichomes, those of the base botuliform, hyaline, the opening seen from above is oblate, elliptical, .56" [1.4 cm] wide; the obovate-trapeziform, obtuse rounded, staminode in natural position is .54" [13.5 mm] long, .46" [11.5 mm] wide below the apex, yellow, with an oblong dent on each side, hairy on the distal part, the trichomes acuminate; the stigma .22" [5.5 mm] long, .224" [5.6 mm] wide, the T-shaped groove is deep; the lobe half-oblate-elliptical; the anthers are .1" [2.5 mm] long, .124" [2.6 mm] wide and the locules are attached together."
