Aristolochia debilis / Umanosuzukusa ウマノスズクサ

 　
Aristolochia debilis is a perennial herb inhabiting river banks, fields, or forest edges, with the whole plant hairless and tinged with glaucous stems, slender and robust, branching well to entangle other plants. Leaves are alternate, 4-7cm long, triangular-ovate, with heart-shaped bases on either side that project sideways in an earlobe-like manner. Leaf axils bear single saxophone-shaped flowers. The curve is loose in the calyx tubes, 2-4cm long; their tips are flat, as if cut off, and bend backward. Bloom time: July-September.
