Abstract
A growth study of an acaulescent palm, Johannestezjsmarmia lanceolata J.Dransfield was carried out in Angsi Forest Reserve, Negeri Sembilan, Malaysia for a period of 19 months. A total of 32 adults, 24 juveniles and 32 seedlings from 3 different plots were censused every two-weeks. The results showed that the average numbers of new leaves entering the crown per year were: - 2.1 leaves for the adult, - 1.6 leaves for the juvenile, - 0.8 leaves for the seedling. From the calculation, it was discovered that the time spent by each leaf in the crown before it died was 8.8 years for adult and 8.4 years for juvenile. Unfortunately, the data for seedling is insufficient to calculate its leaf life span.
