Pound, 1938a: [POU38A] type 1 - long, generally warty pods with a pronounced bottleneck and a conspicuous point, type 2 - lack the pronounced bottleneck, type 3 - pods shorter and lack both the pronounced bottle neck and point, type 4 - smooth lagarta, ie with bottle neck and point but with shallow furrows and a smooth shell, type 5 - as type 1 but with very small beans, type 6 - short, 10 ridged oval, warty pods, sometimes with red tint. Posnette, 1945A [POS45A]. Parinari type has long petioles (2-3 cm) with pulvini separated by a long, deep constriction even when young. The stamen filaments are not pigmented.

Notes:  Selections from the region around Parinari.

Pound, 1938a [POU38A]. Pods probably collected from some 20 trees free of Witches' Broom in a population of type 1,2,3, and 4. Further collections may have made around Porvenir (between the Boca del Huallaga and Boca del Pastaza) from types 5 and 6.

Pound, 1943b [POU43B]. 277 plants were planted at Marper farm.

Bartley, 1998a [BAR98A] Parinari means tree and it is the name of a place on the River Amazon (Maranon) in Peru. However it is believed to refer to a region rather than a specific place. Types 5 and 6 were collected from along the whole stretch of the Maranon River.
