Allanblackia (Clusiaceae) is dioecious. Nine species of Allanblackia are indigenous to the African tropics of which three (A. stuhlmannii, A floribundaand A. parviflora) have known mportance in food (margarine) and cosmetic (soap and detergent) industries.The oil from the seeds containing 5258%stearic acid and 3945% olei acid requires less chemical processing compared to otheroils. The fatty acid profile of the oil has been reported to lower plasma cholesterol levels and thereby reduce the risk of heart attacks besides other uses.

Preliminary survey of clonal variation in rooting of Allanblackia floribunda leafy stem cuttings
Clonal and cutting stem morphology variations in rooting ability were simultaneously examined in Allanblackia floribunda Oliv. using leafy stem cuttings in two experiments. The hypothesis tested is that clonal variation in rooting percentage is due to variation in cutting morphology. Each of the four replicate blocks used per experiment consisted of 18 treatments from two crossed factors, diameter or length × clone, making a total of n = 216 cuttings (3 cutting lengths (3, 4, and 5 cm) or diameters (2, 3, and 4 mm) × 6 stumps (clones) × 12 cuttings, as each experimental unit consisted of 12 cuttings). The cuttings were used for rooting in nonmist propagators. No clone × cutting diameter and clone × cutting length interactions (P = 0.293 and 0.513, respectively) on rooting percentage were found at the end of the study. Highly significant and significant clonal variations in rooting percentage were noted throughout the experiments. Results from this study reject the hypothesis being tested. Finally, further work should be done on the effects of physiological status of the cuttings and clonal variation in this species.
