Pinanga javana is an endemic palm species that only grows on Java, especially in the montane forest. Information about the ecology of P. javana has not been widely revealed, especially concerning growth and distribution patterns in nature. The data is needed to support the success of this type of conservation effort. The study aimed to explain the pattern of distribution and development of P. javana growth in its natural habitat. The method of data collection was done by making a sampling measuring 10x10 m. The research location was located on the eastern slope and the southern slope of Mt. Slamet. Data analysis used the Morisita index to find out the distribution patterns. Descriptive analysis was used to explain the development of P. javana growth. The results showed that the pattern of the distribution of P. javana in its natural habitat was spread in groups. The morphological development of P. javana growth follows the Corner architecture model. Seeds of P. javana are included in the recalcitrant seed type and are hypogeal sprouts. The dispersal agent of P. javana seeds is carried out by a common civet palm (Paradoxurus hermaphroditus).
