features

The threefold pinellia is a spring green, perennial herbaceous plant that reaches heights of 20 to 30 centimeters. It forms spherical bulbs as persistence organs, which have a diameter of about 12 mm. Nodules are formed in the leaf axils. The two to five stalked leaves are three-part and 5 to 6, rarely up to 12 centimeters long. The petiole is 15 to 20 cm long. The middle leaflet is oblong-lanceolate.

It is single sexed ( monoecious ). The inflorescences typical of the Araceae family are formed. The inflorescence stem is 25 to 35 cm long. The flask is divided into a male, sterile and female section. The green to whitish-green and violet at the edge spatha is above the rest of the female, 2 cm long portion of the inflorescence inwardly constricted, green outside and inside dark purple. The spathe is 5 to 7 centimeters long, blunt and its cauldron is closed at the bottom. The sterile part of the flask is 3 mm long. The male section is 5 to 7 mm long. The piston process is much thicker than the spathe and has a diameter of 3 millimeters at the base.

The flowering period extends from May to July. The pollination is carried by midges .
