For description and discussion see Field Mus. Publ. Bot. 13(4) [Fl. Peru]: 694, 1958. On the basis of a few additional collections, the following supplementary description can be provided.

Pedicels and hypanthia probably usually finely strigose with scattered pale hairs; leaves up to 20 c m long; petioles with a broadly concave and obtusely margined channel 1 mm wide extending the whole length on the adaxial side; midvein sometimes convex, often channeled between two narrow convex ridges; raceme-axis up to 5-10 m m long, somewhat woody, compressed, 1-1.5 m m wide; flowers 2-4 pairs; pedicels usuahy 2-5 m m long (only in the type up to 10 m m long); bracteoles more or less conduplicate and forming a bilobed involucre 2.5-3.5 m m from tip to tip; buds (before the petals open) 7-9 m m long; petals "pale lilac," 10-12 m m long [in no. 36722]; ovules 6-8 ["Germen 6-8-ovulatum" according to Berg], or 18-20 in each locule [in no. 36722].

The specimens cited above are superficially more like the type-collection of Eugenia congestissima {Ule 6362; cf Field Mus. neg. 23528) than like the typecollection of E. dittocrepis (Poeppig 3109; cf Field Mus. neg. 23536). In the latter the leaves are rather more short-acuminate and the pedicels are longer; the number of ovules, as reported by Berg, is only about half that found in other collections. The group of E. dittocrepis, sens, lat., may eventually prove to include more than a single species; it seems that the inclusive group is rather widely distributed in the Amazon basin, although few specimens of it are in herbaria. A local population that evidently belongs to the same or a related group is known from several collections from the vicinity of Belem, Para, and is described above under the name of E. belemitana.
