Discussion:

Psidium grandiflorum Aubl., PI. Guiane Fr. 483. pi. 190. 1775.

Campomanesia poiteaui Berg, Linnaea 27: 432. 1856.

For description see Amshoff (Fl. Suriname 3(2): 158. 1951). This species, and Campomanesia lineatifolia, are readily recognized by the large solitary 5-merous flowers usually arising from leafless nodes at the bases of leafy branchlets, by the broad thin leaves (suggesting those of some species of Prunus or Pyrus) with ascending arcuate veins, and by the crowding together of the lowermost pairs of lateral veins. The type of Psidium grandiflorum came from French Guiana, "dans I'ile de Caienne"; an Aublet specimen at B M , which I saw in 1965, may be taken as the type; it is a good flowering specimen, with leaves tufted beneath in the vein-axils. Campomanesia poiteaui was based upon collections from "Guiana Gallica (Poiteau, Rich. Schomb.)," that Berg saw "florif. in herb. Kunth. sub nomine Psidii grandiflori Aubl. et in hb. Berol." Presumably these specimens have been destroyed. A specimen at Kew, ex hb. J. Gay, collected in "Guiane" by Poiteau, may be taken as lectotype; it was compared with Aublet's specimen of Psidium grandiflorum at B M by Sandwith in 1931, and stated to be the same species; it was annotated by Amshoff "in 1947 as the type-collection of C. poiteaui. Three specimens at G, cohected by Poiteau in 1819-1821, probably represent a part of the same gathering; ah are typical of C. grandiflora as I understand it.
