bing ; probably referable here also is Rel. Robins. 1709, from Hitoe messen, 

 Amboina, November 6, 1913, in forests, altitude about 150 meters, with 

 smaller, narrower stipules and apparently more fleshy, slightly larger 

 fruits than the other specimens. 



The Amboina specimens, typical Antidesma amboinense Miq., 

 differ from material of Antidesma stipulare Blume from Nusa 

 Kambangan, the type locality of Blume's species, and from Java 

 in some details, notably in their larger, differently shaped sti- 

 pules, but I have followed J. Mueller in the reduction of Anti- 

 desma amboinense Miq. to Antidesma stipulare Blume. Arbor 

 nuda Rumph. was reduced to the genus Antidesma by Teysmann, 

 as quoted by Hasskarl, Neue Schlussel (1866) 54. 



The details of the figure are not good, the leaves being rep- 

 resented as with but 5 to 8 pairs of nerves, while in the Amboina 

 specimens there are usually about 15 pairs of nerves, and the 

 characteristic stipules are not shown at all. However, these are 

 indicated in the description thus: ' 'folia * * * suprema 

 vero prope suum ortum unum alterumve gerunt foliorum seu 

 squamulas." In spite of the discrepancies between the figure 

 and the specimens cited above, I am confident that Arbor nuda 

 Rumph. is here correctly interpreted, although some future mo- 

 nographer may prefer to reinstate Miquel's Antidesma amboin- 

 ense as a species distinct from the Javan Antidesma stipulare 

 Blume.

This is not represented in our Amboina collections. The 

 reduction of Granum moluccanum to Croton tiglium was first 

 made by Linnaeus, in Stickman Herb. Amb. (1754) 16, Amoen. 

 Acad. 4 (1759) 126, Syst. ed. 10 (1759) 1275, Sp. PL ed. 2 (1763) 

 1426, which is the correct disposition of it, and which has been 

 accepted by all authors.
