Pedicel/hypanthium The pedicel is articulate in all species of Lecythidaceae. In some species the hypanthium tapers to the articulation and resembles a pedicel and, in other species, the hypanthium is truncate and does not resemble a pedicel. Thus, everything from the calyx to the articulation and from the articulation to the rachis is called the pedicel/hypanthium. Very immature fruits of an unknown species of  Eschweilera. Photo by S. A. Mori
Pedicel/hypanthium tapered to articulation The pedicel/hypanthium is tapered gradually to the ariculation such that a true pedicel appears to be present Pedicel/hypanthiuim of Eschweilera biflava. Photo by R. Aguilar.
Pedicel/hypanthium truncate at articulation There is no clear cut pedicel in this type of pedicel/hypanthium Pedicel/hypanthium truncate as shown in Eschweilera spccostarica

Smooth hypanthium A hypanthium that does not have furrows or conspicuous outgrowths. Pedicel/hypanthiuim of Eschweilera biflava. Photo by R. Aguilar.
