T. ampliplacenta is a perennial herb with a cylindrical rhizome.[2] It has mauve leaves at the apex.[2]
T. ampliplacenta differs from T. integrifolia by having involucral bracts which are roughly decussate and having the two inner bracts ovate oblong whereas T. integrifolia's innermost bracts resemble rabbits' ears. [2] It differs from T.chantrieri by having the seeds tightly connected to the flesh and difficult to separate from the flesh.[2] There are five to ten radical pinnately nerved leaves. The red-wine coloured flower stalks are axillary.[2] The inflorescence is an umbel with up to 25 flowers, which have four involucral bracts.[2] The flowers are triangular and greenish purple when young.[2] The buds are a black-purple. There are three petal like stigmas.[2]
It flowers from early July to late August and fruits the following year from June to July.[2]
