Populations with high %C have fewer achenes per head ([r.sub.%C,N] = -0.75), a greater percentage of awned achenes ([r.sub.%C,%A] = 0.70), and the shift from awned to nonawned achenes occurring on longer, thinner achenes ([r.sub.%C,SAWN] = 0.76).
The first principal component accounts for 58% of the variation in morphology and is strongly positively correlated (r [greater than or equal to] 0.80) with the percentage of central achenes, the distance of maximal shape shift from the center of the head, length and narrowness of the most extreme central and peripheral achenes, and the length and narrowness of achenes where the shift from awned to nonawned achenes occurs.
