RUMPHIUS'S HERBARIUM AMBOINENSE 



acerifolia Blume. Later Blume made it the type of Shorea 

 selanica Bl. var. latifolia BL, which is perhaps the correct dis- 

 position of it. The forms described in this chapter as Caju cawan 

 e Java and Dammar leomelaena are undeterminable; the latter is 

 probably a species of Canarium. 



DRYOBALANOPS Gaertner 



DRYOBALANOPS AROMATICA Gaertn. Fruct. 3 (1805) 49, t. 186. 



Arbor camphorifera II occidentals Rumph. Herb. Amb. 7: 65, 68. 



The general discussion of camphor includes the true camphor, 

 Cinnamomum camphora T. Nees & Eberm., as well as that 

 produced in Malaya, the resin of Dryobalanops aromatica 

 Gaertn. This reduction was made by Blume, Mus. Bot. 2 (1851) 

 38, and by de Vriese, who placed it under Dryobalanops cam- 

 phora Colebr., a synonym of D. aromatica Gaertn. 



DIPTEROCARPUS Gaertner 



DIPTEROCARPUS sp.? 



Arbor koring Rumph. Herb. Amb. 2: 74. 



The reduction of Arbor koring to Dipterocarpus is based 

 wholly on the observation made by Hamilton that the oil produced 

 by the tree was secured by the same method as that used in 

 gathering the oil of Dipterocarpus. The probabilities are very 

 great that this is the correct disposition of Arbor koring. No 

 further reduction of it is possible from the data given by 

 Rumphius. 



BIXACEAE 



BIX A Linnaeus 



BIXA ORELLANA Linn. Sp. PI. (1753) 512. 



Pigmentaria Rumph. Herb. Amb. 2: 79, t. 19. 



Pigmentaria Rumph. was first reduced to Bixa orellana Linn, 

 by Linnaeus, in Stickman Herb. Amb. (1754) 9, Amoen. Acad. 

 4 (1759) 120, Syst. ed. 10 (1759) 1074, which is manifestly the 

 correct disposition of it and has been accepted by all authors. 



FLACOURTIACEAE 



PANGIUM Reinwardt 

 PANGIUM EDULE Reinw. in Syll. Ratisb. 2 (1828) 12. 

 Pangium Rumph. Herb. Amb. 2: 182, t. 59. 

 Amboina, Kati-kati, Robinson PI. Rumph. Amb. 212, October 20, 1913, 

 in light forests, altitude about 75 meters, locally known as pangi.
