RUMPHIUS'S HERBARIUM AMBOINENSE 



that can be definitely said regarding the Rumphian plant is that 

 it was a small composite with yellow flowers and pappiferous 

 achenes. 



COMPOS1TAE ? indet. 



Pilosella amboinica Rumph. Herb. Amb. 6: 148. 



The description is not sufficiently definite to warrant an identi- 

 fication of the plant. Hasskarl, Neue Schliissel (1866) 177, 

 thought that it might be a species of Vernonia. Two forms are 

 described, with blue and with white flowers. 



SPECIES DESCRIBED OR MENTIONED BY RUMPHIUS THAT CANNOT 

 BE DEFINITELY REFERRED TO THEIR PROPER FAMILIES 



Below are listed forty-six Rumphian species that cannot, from 

 data at present available, be definitely referred to species de- 

 scribed under the binominal system. Other species of somewhat 

 similar doubtful status occur in the Herbarium Amboinense; 

 but those that can be definitely referred to their proper families, 

 genera, or probable species are discussed under the family, 

 generic, or specific names, as the case may be, in the preceding 

 systematic enumeration. It is very doubtful if many of the 

 species listed below can be definitely determined, yet some of 

 them can be certainly placed through field work carried on with 

 special reference to the native names cited by Rumphius. From 

 a systematic standpoint, however, these remaining doubtful 

 Rumphian species are of no importance, as in no case has a 

 binominal been based on any of the descriptions. 



Lignum moschatum Rumph. Herb. Amb. 2: 41. 



Under this name three kinds of wood are described. There 

 is no description of the plants themselves. The only suggested 

 reduction is that of Henschel, Vita Rumph. (1833) 146, who 

 quotes Hamilton's opinion that at least one of the species is 

 Limonia acidissima Linn. There is little or no authority for this 

 reduction. 



Lignum tsjidji Rumph. Herb. Amb. 2: 50. 



Under this name a wood is described, which according to 

 Rumphius came from Kwangtung, Cambodia, and Siam. The 

 only suggested reduction is that made by Henschel, Vita Rumph. 

 (1833) 146, who referred it to Erythroxylum monogynum Roxb. 

 The range of Roxburgh's species, India and Ceylon, makes this 

 reduction an impossible one.
