Identification
‘Pecam’ leaves are ovoid, dark green on the upper surface and greyish green below. The leaf edge is slightly toothed. Leaf stalks pinkish.

Typical uses, site requirements, pest and disease resistance
‘Pecam’ is very hardy, and performs well in most environments except for coastal sites. It is rust resistant. ‘Pecam’ is the least vigorous of the maxi-nigra clones. Survival rate was highest of all the maxi-nigra clones in field trials. Height and DBH at age 7 (age 12) in a sheltered site was 9.4 (17.4) m and 12.5 (17.4) cm and in a windy site was 6.5 (10.2) m and 10.8 (14.2) cm. Suitable for soil conservation. This clone is ideal where a healthy, slow growing tree is required. Could be prone to cattle damage.
