Bramasto Y, Sudrajat DH, Rustam EY. 2015. Diversity of morphology Anthocephallus macrophyllus and Anthocephallus cadamba depend on the dimension of fruit, seed and leaves. Pros Sem Nas Masy Biodiv Indon 1: 1278-1283. White jabon (Anthocephalus cadamba) and red jabon (Anthocephalus macrophyllus) are the potential species which currently has already develop rapidly. The objectives of this research were to investigate whether there are variations of morphology among of those species based on the dimensions of fruit, seeds, and leaves. The distribution of white jabon is quite large enough with the condition of diverse geo-climate, ranging from Sumatra to Papua, but the distribution of red jabon relatively more narrow, only found in several places in eastern Indonesia (Sulawesi and Maluku). In general, there are differences in terms of the size of fruit and seed between white and red Jabon. The weight of fruit of white jabon range between 28.15-111.25 grams, while red jabon range between 36.32-98.21 grams. The average of the bigger fruit diameter (DB) of white jabon is 44.3-64.5 mm and the average of the narrow fruit diameter (DK) is 41.7-58.0 mm, while the average of DB and DK of red jabon is 44.36-56.28 mm and 47.20-56.25 mm. Seed dimension (length and diameter ) of the white jabon ranged from 570.7- 635.6 I¼m and for the diameter of seed between 399.7-471.0 I¼m. Otherwise the size of the seed of red jabon relatively greater than the seed of white jabon, especially for seed origin from Manado. The average seed length of red jabon are 587.8-694.6 I¼m and the average of diameter are 383.4-481.9 I¼m. The average length of white jabon leaves ranges 23.90-29.70 cm, wide leaves 12.70-1.30 cm, length of petiole 3.20-4.30 cm and the amount of bone leaves 26-28. There are variations between the population in the size of fruit, seed, and leaves of jabon, but those characters do not correlate with altitude, lines of longitude, rainfall and temperature of the site.
