RUMPHIUS'S HERBARIUM AMBOINENSE 



tation of the species is correct. Rumphius states that Songium 

 was known in Amboina as aylassalinu and as ay macaninu, in 

 Celebes as songi and songo, and in Java as sambu. Sempu is 

 one of the Javanese names for Dillenia indica Linn., the only 

 white-flowered Dillenia reported from Java, so that the Javan 

 reference included by Rumphius probably refers to Dillenia 

 indica Linn. Linnaeus reduced both t. J^5 and J>6 of Rumphius 

 to Dillenia indica Linn., in Stickman Herb. Amb. (1754) 9, 

 Amoen. Acad. 4 (1759) 121, Syst. ed. 10 (1759) 1082, but later 

 authors have followed Thunberg in the disposition of t. 4-5. Lin- 

 naeus was manifestly wrong in his reduction of t. U6, which is 

 the following species. Miquel, Fl. Ind. Bat. I 2 (1858) 11, erro- 

 neously reduced Dillenia elliptica Thunb. to D. speciosa Thunb., 

 which is a synonym of D. indica Linn.

 Sangius mas et femina Rumph. Herb. Amb. 2: 142, t. 4.6. 



This species is not represented in our Amboina collections. 

 Dillenia serrata Thunb. was based wholly on Rumphius and 

 must be interpreted from the Rumphian figure and description. 

 Linnaeus erred in reducing this plate to his Dillenia indica, in 

 Stickman Herb. Amb. (1754) 9, Amoen. Acad. 4 (1759) 121, 

 Syst. ed. 10 (1759) 1082. All authors since Thunberg have 

 been content with calling it Dillenia serrata, although the exact 

 status of the species is quite uncertain. It seems probable that 

 more than one species is included in the Rumphian description, 

 as he gives the range as Amboina, Celebes, and Java. It was 

 said by Rumphius to be abundant in Celebes at Tambocco, near 

 Macassar, and at Toletae. Dillenia ochreata Teysm. & Binn. 

 should be compared critically with Dillenia serrata Thunb., as 

 it is probably identical with Thunberg's species.
