For description see Amshoff (Fl. Suriname 3(2): 104. 1951). The fohowing details are supplementary: Midvein prominently convex above; bracteoles cordateovate, overlapping or connate at base, 2 m m long, 2.5 m m wide at base; bracts similar, shorter; buds closed except for a small apical pore, the globe of the calyx about 5 m m in diameter, thinly tomentulose and in addition with some long hairs especially at the tip, the surface pubescent just inside the pore; anthers 1.3 m m long. The syntypes of Calycorectes grandifolius were from "Cayenne (Martin)" and "Guiana Batava (Kappler, coll. no. 1365)," seen by Berg "in hb. Kunth. et Kegel." I have not seen the types, if they still exist. Amshoff (Rec. Trav. Bot. Neerl. 39: 156. 1942) designated Kappler 1365 as "cotypus"; following her lead, I designate as lectotype the sheet of this number at P, ex hb. Steud., a good leafy specimen with several buds, annotated by Berg; additional specimens of the same number (isolectotypes) are at G, P, and U. The species seems to be known only from Suriname and French Guiana.

Amshoff (Rec. Trav. Bot. Neerl. 39: 156. 1942 and Fl. Suriname 3(2): 58, 104. 1951) emphasized the fact that the corolla in this species is 6-merous, a fact already noted by Berg. In her 1942 paper she went so far as to suggest that on this account the genus might be considered monotypic, as all other known species thought to belong to Calycorectes had 4 petals. It is true that in the specimens I have examined there are 6 petals, but in the Myrtaceae the number of flower-parts is rarely entirely consistent within any large genus, and I do not think this alone is enough to justify any generic segregation
