PIPERACEAE 



185 



Herb. Amb. (1754) 27, Amoen. Acad. 4 (1759) 135, Sp. PI. 

 ed. 2 (1762) 42, in which he was followed by Burman f., Fl. Ind. 

 (1768) 15. It is the type of Piper subpeltatum Willd., which 

 C. de Candolle considers to be a variety of Piper umbellatum 

 Linn., in Donn.-Sm. Enum. 6:39, Philip. Journ. Sci. 5 (1910) 

 Bot. 463. Lomba has also been cited by various authors under 

 the synonyms Peperomia subpeltata Dietr., Peperidia subpeltata 

 Kostel., and Potemorphe subpeltata Miq. 



PIPER SARMENTOSUM Roxb. Fl. Ind. 1 (1820) 162. 



Sirium terrestre Rumph. Herb. Amb. 5: 344, t. 119, f. 1. 



Amboina, Robinson PL Rumph. Amb. 56, July 17, 1913, along roadsides 

 in the vicinity of the town of Amboina, July 17, 1913, locally known as 

 siri rambang. 



Miquel, Fl. Ind. Bat. I 2 (1858) 446, thought that Sirium 

 terrestre might be Chavica sphaerostachya Miq., but C. de Can- 

 dolle, Prodr. 16 1 (1869) 389, definitely excludes it as a synonym 

 of Miquel's species, and refers it, 1. c. 360, to Piper arcuatum 

 Blume. The specimen, however, which certainly represents the 

 form that Rumphius described and figured, is not at all Piper 

 arcuatum Blume, but is typical Piper sarmentosum Roxb. 



PIPER sp. 



Sirium frigidum rotundifolium Rumph. Herb. Amb. 5: 345, t. 119, /. 2. 



This is not represented in our Amboina collections. Vahl, 

 Enum. 1 (1804) 333, referred it to Piper diffusum Vahl, a species 

 based on Ceylon specimens and which is apparently the same 

 as Piper argyrophyllum Miq.; see Trimen Fl. Ceyl. 3 (1895) 

 429. Miquel, Fl. Ind. Bat. I 2 (1858) 441, thought that it might 

 be Piper sarmentosum Roxb., but the other form figured on the 

 same plate, Sirium terrestre Rumph., is Piper sarmentosum 

 Roxb. and is different from Sirium frigidum rotundifolium 

 Rumph. The form described as Sirium frigidum latifolium Rumph., 

 Herb. Amb. 5 : 345, is indeterminable. Hasskarl, Neue Schlussel 

 (1866) 131, thought that it was Piper album Vahl, but there is 

 no reason for considering that this reduction is correct. 



PIPER sp. 



Pharmacum magnum parvifolium Rumph. Herb. Amb. 5: 42, t. 26, 

 f. 2. 



Nothing in our Amboina collections matches this figure. The 

 species is indeterminable from the data at present available. 



PIPER sp. 



Pharmacum magnum marinum Rumph. Herb. Amb. 5: 42. 



Indeterminable from data at present available.
