Discussion:

Eugenia quitarensis Amsh., Rec. Trav. Bot. Neerl. 42: 12. "May 1950," non Benth. 1840.

Eugenia coriacea Berg, Linnaea 30: 694. 1861, non Dietr. 1815-20.

Eugenia polystachya sensu Berg, Linnaea 27: 289. 1856.

type of this name is Schomburgk 691, in the Vienna herbarium, the only specimen cited by Berg in his description of "Eugenia polystachya" in 1856. In proposing a new name for this taxon (Linnaea 3 0 : 696-697. 1861) Berg contrasted his new E. coriacea with E. polystachya as follows:

1. Indument shortly strigose; leaves substrigose beneath, widest at middle; leaves and flowers larger; racemes longer, stouter; bracteoles rounded, glabrous, 2 m m long. E. polystachva.

1. Indument tomentellous; leaves glabrous, widest near base; leaves and flowers smaller; racemes shorter, more slender; bracteoles rotund-ovate, puberulent, 1 m m long. E. coriacea.

At Vienna in 1966 I was unable to locate the type of Eugenia coriacea. I have seen isotypes at C G E and at K, but I can add little to Berg's characterization. The leaves, inflorescences and flowers of Schomburgk's plant are smaher than usual in the E. polystachya-complex and the pubescence is more spreading than appressed. Apparently nothing like it has been collected in recent years. Specimens of another species from the interior of Suriname and British Guiana, with narrow leaves and appressed-strigose or nearly glabrous racemes, have been distributed from K e w and elsewhere as E. polystachyoides; for another interpretation of these, see under E. florida.
