RUMPHIUS'S HERBARIUM AMBOINENSE 



PIPER BETLE Linn. Sp. PI. (1753) 28. 



Siriifolium Rumph. Herb. Amb. 5: 336, t 116, f. 2. 



The common betel pepper is not represented in our Amboina 

 collections, yet Piper betle is manifestly the correct disposition 

 of Siriifolium Rumph. Linnaeus reduced it, through error, to 

 Piper longum Linn., in Stickman Herb. Amb. (1754) 22, Amoen. 

 Acad. 4 (1759) 131, and later, Sp. PI. ed. 2 (1762) 41, placed 

 it under Piper malamiris Linn., which is apparently a synonym of 

 Piper betle Linn. Radermacher, Loureiro, Roemer and Schultes, 

 Blume, and other authors cite it under Piper betle Linn., and 

 Miquel cites it under Chavica betle Miq. 



PIPER BETLE Linn. var. SIRIBOA (Linn.) C. DC. Prodr. 16 1 (1869) 359. 

 Piper siriboa Linn. Sp. PI. (1753) 29. 

 Siriboa Rumph. Herb. Amb. 5: 340, t. 117. 



Siriboa Rumph. was originally reduced to Piper siriboa Linn., 

 in Stickman Herb. Amb. (1754) 22, one year after the publica- 

 tion of the species, and has been very consistently cited under 

 this name in subsequent botanical literature. The forms de- 

 scribed by Rumphius as / alba, II cambing, and 77/ fragrans 

 are apparently but variants of Piper betle or the variety siriboa. 



PIPER AMBOINENSE (Miq.) C. DC. Prodr. 16 2 (1869) 347. 



Chavica amboinensis Miq. Ann. Mus. Bot. Lugd. Bat. 1 (1863—64) 

 i . 134. 



Sirium arborescens tertium alterum Rumph. Herb. Amb. 5: 48. 

 Amboina, Mahija, Batoe gadjah, and near the town of Amboina, Robin- 

 son PL Rumph. Amb. 58, ascending to an altitude of 250 meters, climbing 

 on trees, locally known as siri seytan. 



The specimen cited above represents a characteristic species 

 of Piper, and it is probably the form described by Rumphius, here 

 reduced to Piper amboinense C. DC. 



PIPER REIN WAR DTI AN U M (Miq.) C. DC. Prodr. 16 1 (1869) 354. 



Macropiper reinwardtianum Miq. in Linnaea 21 (1848) 481. 



Sirium decumanum album Rumph. Herb. Amb. 5: 45. 

 Ambonia, Wae, Lateri, and Halong, Robinson PL Rumph. Amb. 60, 

 August and November, 1913, in light forests, altitude from sea level to 

 150 meters, locally known as siri utan, siri tallan, and siri tallan perampuan. 



The specimen cited here probably represents the form that 

 Rumphius described. Vahl, Enum. 1 (1804) 334, referred the 

 Rumphian species to Piper album Vahl, a species based on Javan 

 specimens and one of doubtful status. There is no particular 

 reason for believing that the Amboina' plant is the same as the 

 Javan one described by Vahl, but it does appear from the descrip- 

 tion to be referable to Piper reinwardtianum C. DC.
