PIPERACEAE

(1814) 80.* The species was later briefly described by Roxburgh 

 from specimens collected in the Moluccas, the reference to 

 Rumphius being included in the description. The description 

 applies to the above specimens in all respects, and is not at all 

 Thottea dependent Klotzsch, as reduced in Index Kewensis. The 

 actual Amboina specimens were determined by C. de Candolle 

 as Piper miniatum Blume, Blume's species thus becoming a 

 synonym of Piper arborescens Roxb. In Stickman's Herb. Amb. 

 (1754) 19, it is erroneously referred to Piper malamiris L.

Blume was certainly correct in referring this Rumphian 

 species to Piper caninum Blume. Loureiro, Fl. Coehinch. (1790) 

 30, discussed it under Piper sylvestre Lour., while Roxburgh, 

 Fl. Ind. 1 (1820) 161, reduced it to Piper cubeba; Piper cubeba 

 Roxb., non Linn., is a synonym of Piper caninum Blume.

Sirium decumanum Rumph. is the whole basis of Piper decu- 

 manum Linn, as originally published and is hence the type of 

 the species; Linnaeus took his specific name decumanum from 

 Rumphius. Later he added also a reference to Plumier, Amer. 

 59, t. 76, which represents a species totally different from Sirium 

 decumanum. C. de Candolle, Prodr. 16 1 (1869) 370, interpreted 

 Piper decumanum Linn, from the reference to Plumier and de- 

 scribed the Amboina species as Piper forstenii C. DC. Some of 

 the early authors referred it to Piper methysticum Forst., bub 

 it has nothing to do with Forster's species. It has al§o been cited 

 under Piper majusculum Blume and Chavica majuscula Miq., 

 while Miquel referred it to Chavica rumphii Miq. Both Blume's 

 and Miquel's species are apparently different from Piper decu- 

 manum Linn. (P. forstenii C. DC.) as here interpreted.
