Homalomena bellula Schott belongs to the Araceae family. It is an endemic and rare species (vulnerable, according to IUCN criteria) of Java. In addition, H. bellula has a unique shoot architecture which differs from that of other Javanese Homalomena. The shoot architecture of H. bellula resembles that of ginger’s, closely conforming to Tomlinson’s model. Schott described this Javan species in his Protologue published in 1863. Since then, the species had not again been encountered in the field, until its rediscovery in recent years. The aims of this study were to provide an account of the occurrence of H. bellula in its natural habitat, to describe its shoot organisation, and to report on efforts undertaken to conserve the species. Field observations and studies based on herbarium specimens and living specimens were used in the research. Based on type specimen data, the locality of the original specimen was cited as Mount Halimun in West Java. Several field investigations in Java found that H. bellula occurs in Pancuran Tujuh, on the slope of Mount Slamet, Baturraden, Central Java. An ex situ conservation effort is necessary to sustain this species because the population within its natural habitat is alarming.
