Notes:  Almeida et al., 1987 [ALM87A] CAB [BRA] material includes collections from all over the Brazilian Amazon basin. The first CAB clone was collected in 1971 and the series continues to grow. All CAB material will have been collected under a provisional name and given a CAB number at a later date. Numbers given above 5000 indicate seedling progeny from a collected pod; numbers below 5000 are budwood collections. Material in the CAB series has been collected on a large number of expeditions by a great many collectors. Details of collection, collector and expedition of individual CAB clones will be listed in more detail under the provisional group name.

The system involved in naming the collections is as follows:

a) in most of the expeditions both vegetative and seed propagating material was collected from the parent trees, however for various reasons it was possible only to obtain only budwood or fruit from some trees;

b) all material collected was numbered in sequence as it was collected, the collection (provisional) identifier was alpha-numeric, identifiying the state in which the parent tree is located;

c) where both budwood and fruit were collected from a tree (and only in such cases) the budwood (future clone) identifier was given the first and the fruit identified with the succeeding number (there are a few errors, however);

d) as such, families of progenies obtained from a fruit have only one corresponding clone, or a clone can only have one progeny family, in the permanent identifiers (CAB numbers);

e) in most cases, in several expeditions, the succeeding progeny collection (provisional) identifier refers to the clone of the same tree (but this is not necessarily always the case);

f) when there is a gap in the sequence of the collection (provisional) identifiers a CAB progeny identifier (i.e. 5000 and above) cannot be related to the preceeding clone identifier. e.g. CAB 0342/AM 417, CAB 5437/AM 420: here CAB 5437 cannot be the progeny of CAB 0342, the corresponding budwood for CAB 5437 could have been AM 419 which was lost in propagation.
