Pound, 1938a [POU38A]. Fruit - unpigmented, half blanco, long oval, slightly warty, no conspicuous point nor bottle neck. Bartley, 1995a [BAR95A]. Pound describes the typical NANAY as above (pod colour between light/intermediate green) but fruits with different characteristics appear among the NA clones of today which result from seedling progenies of the original collections. Posnette, 1945a [POS45A]. Fan branches are characterised by relatively short (less than 2 cm) petioles in which the pulvini are not clearly separated until the leaf ages, when a shallow constriction may develop. The stamen filaments are always pigmented to some degree, usually heavily.

Notes:  Collected in 1937.

Pound, 1938a [POU38A]. Pods were probably collected from 14 trees which were free of witches' broom disease.

Pound, 1943b [POU43B]. 708 plants were planted at Marper farm.
