A survey of the genus Lasianthus in Mount Burangrang, West Java

A survey of the genus Lasianthus and its morphological study based on living specimens was conducted at the Mt. Burangrang, West Java, in order to update the existing Lasianthus data. Sampling was carried out in three regencies around the Mt. Burangrang: West Bandung, Subang and Purwakarta. A total of 19 species were recorded from Mt. Burangrang. Those species covered three sections: sect. Nudiflorae (nine species), sect. Lasianthus (nine species) and sect. Stipulares (one species). Based on the collected specimens, the delimitation of the Asian Lasianthus as having 3-9 pyrenes is no longer applicable. The specimens of L. capitatus from the Mt. Burangrang contained 9-12 pyrenes. The existence of L. rufus (Korth.) Miq. is also discussed. The details of morphological description of the Mt. Burangrang Lasianthus are provided.
