For description see Amshoff (Fl. Suriname 3(2): 152. 1951, as Psidium parviflorum). In m y opinion the plant of the Guianas which has been called P. parviflorum, and the plant of the middle and upper Amazon that has been called P striatulum, represent one and the same taxon. The types of P striatulum and P turbiniflorum, both of which I studied at Munich in 1966, seem to represent the same species but the herbage in P turbiniflorum is more pubescent, and the buds a little more open. The similarities between these types, and an isotype of P. parviflorum, are convincingly shown in photographs (Field Mus. negs. 19726, 19729, 23494).
