Dipierocarpaceae is the family which dominates tropical rain forest. There are lots of Dipterocarpaceae members which have not been identified yet till the level of species, especially on seedling level, so need Dipterocarpaceae research and development both in the origin habitat or in other places. The objective of this research is to identify, creates determination key and find out the abillity to live Dipterocarpaceae species in the compartment 21. This research was hoped to give information on seedlings of well grown twnty-five Dipterocarpaceae species in the research location. The research took place in comparment 21, RPH Carita, KPH Banten and was done in June till December 2003. The research methods were explorative, descriptive and historic. The design was Completely Randome Block Design, Consisted of 37 seedlots , 10 treeplots, and 4 block. The seedlots observed were 25 species, because the other 90% were dead or destructed. The data anaiysis were used to identify seedlings by comparing the exist publication, and then creating detennination key. The abillity to live of the plants was analized with: counting the live percentage of the plants, then doing F-test to find out the different treatment, ifthere is significantly different, then followed with DMRT test. This identification result explain that the genus Shorea have caracteristic:penninervis secondary nervation with variation on the other morphologis characteristics. The genus Dryobalanops have rectinervis secondary nervation and red young leaf. Genus Dipterocarpus have divisus blade the stipuia are silinder shaped coveringe bud. The Genus Hopea have Dryobalanoide nervatio. The Genus Vatica have thick blade, with domatia near. Based on the morphologis caracteristic then detennination key was made for Dipterocarpaceae seedling. Live percentage for higest nomination five were Vatica sumatrana (93,75%), Hopea odorata (91,25%), Shorea uiiginosa (70%), Shorea selanica (68,75%). While otherwise were Shorea stenoptera (47,5%), Hopea mangerawan (47,5), Shorea accuminatisima (51,25%), Hopea griffithii (51,88%), and Shorea ovalis (53,75%).
