P. laciniata grows in wet meadows or near springs in Western Sichuan near Kangding. It has been collected only a few times and is remarkable for its irregular pinnatifidly incised leaves shown in the herbarium specimens. It was originally associated with P. blinii because of the leaf margin, but it is more closely associated with P. gemmifera. Leaves are oblong with a long petiole, attenuate base, obtuse or rounded apex and an irregular pinnatifidly incised margin. Flowers are pink-purple 3-10 in 1-2 whorls on a scape which may be farinose at the apex. Bracts are lanceolate with a slightly gibbous base.
