Monographs Details: Eugenia quadriovulata Amshoff
Authority: Maguire, Bassett. 1969. The botany of the Guayana Highland-part VIII. Mem. New York Bot. Gard. 18: 1-290.

This is described, but not very fully, by Amshoff, and in Fl. Suriname 3(2): 120, 1951. I have seen only the type, Versteeg 426, from somewhere on the Marowijne River in Suriname; Amshoff cited also a specimen from the Demerara River, British Guiana, Jenman 4052. Apparently the species is a very distinct one. I know of no other species in which the leaves on both surfaces, and also the calyx-lobes and the hypanthium, are coarsely impressed-punctate. The flowers are closely sessile, 2-5 pairs from a very short axis; the bracts are imbricate, indurated and ciliate, about 1 m m wide and less than 1 m m long; the bracteoles are scarious, ciliate, about 1.2-1.5 m m long, gibbous at base on the backs, more or less conduplicate and slightly keeled toward apex, not connate but the edges overlapping, forming a compressed truncate involucre about the substipitate base of the hypanthium ca 1.5 m m long; the calyxlobes are fleshy, somewhat unequal, thin-margined, the outer pair obtusely deltoid, 1.5 m m long and wide, the inner pair obtuse, 2 m m long; the stamens are about 50; the disk in flower is about 2 m m wide, mostly occupied by the staminal ring.
