Phyllanthus Myrtifolius (Moon Ex Wight) MULL.ARG. And Phyllanthus Tenellus Roxb. (Phyllanthaceae) in Java

Abstract

Phyllanthus myrtifolius (Moon ex Wight) Müll.Arg. and Phyllanthus tenellus Roxb. (Phyllanthaceae) in Java. Floribunda 6(5): 188–194. — Phyllanthus L. is the largest genus in the Phyllanthaceae and consists of 1302 species that are widely distributed in tropical and subtropical regions. There were 20 discovered species of Phyllanthus recorded in the Flora of Java. However, additional species of Phyllanthus in Java can still be discovered in the future. Therefore, this research was aimed to report any additional information on Phyllanthus of Java. Field exploration was conducted in Bandung, Bogor, Jakarta, Sumedang, and Situbondo. Field observation resulted in the findings of two Phyllanthus additional species within the Flora of Java, namely P. myrtifolius (Moon ex Wight) Müll.Arg. and P. tenellus Roxb. P. myrtifolius was widely cultivated as an exotic ornamental plant, while P. tenellus is a newly recorded alien species to Java. The discovery of these species would increase the number of Phyllanthus species in Java.

Short Communication: The existence of Homalomena rubescens (Araceae) in Java, Indonesia based on morphological and molecular evidence

“…The lack of updated Flora of Java is exacerbated by the numerous discoveries of new plant alien species in Java. Many newly discovered alien species, including aroids, have been reported to occur on the island in recent years (Mustaqim and Nisyawati 2016;Al Anshori et al 2020;Hariri et al 2020;Effendi and Mustaqim 2021;Mustaqim and Setiawan 2021;Peniwidiyanti et al 2021;Al Anshori et al 2022;Irsyam et al 2022;Irsyam et al 2023). Furthermore, the commerce in ornamental plants has grown significantly, allowing ornamental species to be easily introduced to new geographic areas.…”

“…Some additional alien species of the Euphorbiaceae sensu lato have been discovered on Java over the past five years, both naturalized and cultivated, namely Caperonia palustris (L.) A.St.-Hil. (Al Anshori et al 2020), Cathetus myrtifolius (Wight) R.W.Bouman (Hariri et al 2020), Cnidoscolus aconitifolius (Mill.) I.M.Johnst.…”
