X = pollen was identifed during scan.
a The first number in the two- or three-part sample code is a provenience indicator (PD), the second is a laboratory catalog number (FS), and the third, when assigned, is a point location number (PL).
bAggregate code explanation: The letter or letters preceding the dash refer to the plant taxon (see Table 17.3); the number after the dash refers to the estimated number of grains in the largest aggregate; and the letter following the number refers to the maximum number of aggregates observed (a = 1, b = 2 to 5). Codes in parentheses indicate aggregates observed during the standard scan. Maximum number of aggregates observed was not recorded for scans.
