The difference between purple flower peucedanum and peucedanum

1. Difference of blades

The stem leaves and root leaves of Peucedanum purpurogenum have long petioles, about 13-36 cm, with swollen purple sheaths at the base. The leaves are triangular to oval and are papery. The basal leaves of Peucedanum have petioles, about 5-15 cm long, while the stem leaves are sessile. The leaves are broadly ovate or triangular-ovate in outline.

2. The difference between flowers

The purple-flowered Peucedanum has a compound cyme, which is lateral and terminal. There are 1-3 bracts, which are oval in shape and purple in color. The petals are obovate or elliptical-lanceolate, and the flower color is dark purple. The flowering period is from August to September. The bracts of Peucedanum are linear, the petals are ovate, and the flowers are white. The flowering period is similar to the former.
