 Amb. 310, 311, 312, 313, August and September, 1913, in forests and 

 along rocky river banks, altitude 175 to 325 meters, locally known as 

 polat, polot, and polat puti. 



Burman f., Fl. Ind. (1768) 205, referred this to Croton polot 

 Burm. f., taking his specific name from Rumphius, but de- 

 scribing the species from Javan material. Burman's species 

 has been entirely overlooked by modern botanists and is the 

 species commonly known as Claoxylon indicum Hassk., which 

 should now be called Claoxylon polot (Burm. f.) {Croton polot 

 Burm. f., Claoxylon indicum Hassk.). Henschel, followed by 

 Pritzel, erroneously referred the Rumphian species to Jatropha 

 moluccana Linn. =Aleur it es moluccana Willd. Hasskarl, Neue 

 Schlussel (1866) 69, referred it to Laportea crenulata Gaudich... 

 where it certainly does not belong, although he was correct as 

 to the genus. In the original publication of Urera amplissima 

 Blume no description is given; the name appears on the plate 

 only. Miquel credits it to Java (Teysmann) and the Moluccas 

 (Zippel), but in his second consideration of it he cites only 

 Amboina material collected by Teysmann, Zippel, and Be Fretes, 

 so that the original citation of Teysmann's specimen, as Javan, 

 is probably an error. J. J. Smith f states : "De voor Java 

 opgegeven L. amplissima Miq. is nog niet op Java aangetroffen, 

 doch waarschijnlijk afkomstig van de Molukken. ,,

Folium urens angustifolium Rumph. Herb. Amb. 3: 217. 

 Folium urens rubrum Rumph. Herb. Amb. 3: 218. 



Both descriptions apparently apply to a single species of 

 Laportea, which, from the data given by Rumphius, is perhaps 

 distinct from Laportea amplissima Miq. Hasskarl, Neue 

 Schlussel (1866) 69, thought that Folium urens rubrum Rumph. 



* Retained name, Vienna Code; Urticastrum Fabr. (1759) is older,
