RUMPHIUS'S HERBARIUM AMBOINENSE 



The Rumphian descriptions apply to three forms of this poly- 

 morphous species. The reduction of Ricinus ruber was first 

 made by Linnaeus, in Stickman Herb. Amb. (1754) 16, Amoen. 

 Acad. 4 (1759) 126, Syst. ed. 10 (1759) 1276, Sp. PL ed. 2 

 (1763) 1430. The various forms described by Rumphius have 

 been reduced by authors to Ricinus lividus Jacq., R. viridis 

 Willd., R. africanus Mill., and R. ruber Miq. FL Ind. Bat. I 2 

 (1858) 390; the last is not included in Index Kewensis; all are 

 synonyms of Ricinus communis Linn.

Amboina, Hitoe lama, Robinson PL Rumph. Amb. 332, October 8, 1913, 

 cultivated, altitude about 175 meters, locally known as kamiri. 



Lamarck seems to have been the first author to reduce Cami- 

 rium, placing it under Croton moluccanum Lam., which as 

 Aleurites moluccana Willd. is certainly the correct disposition of 

 it. By various authors it has been referred to Juglans camirium 

 Lour., Aleurites triloba Forst., and A. ambinux Pers. — all syn- 

 onyms of Aleurites moluccana (Linn.) Willd. 



JATROPHA Linnaeus 



JATROPHA CURCAS Linn. Sp. PL (1753) 1006. 



Ricinus americanus Rumph. Herb. Amb. 4: 95. 

 Amboina, Binting, Robinson PI. Rumph. Amb. 333, September 16, 1913, 

 along roadsides at low altitudes, locally known as jarap. 



This reduction was first made by Hasskarl, Neue Schliissel 

 (1866) 81, and is certainly the correct disposition of the plant 

 Rumphius described as Ricinus americanus.

Jatropha manihot Linn. Sp. PL (1753) 1007.

Mandihocca Rumph. Herb. Amb. 5: 361. 

 Amboina, Soja, Robinson PI. Rumph. Amb. 336, a roadside escape, 

 altitude about 375 meters. 



The reductions follow Hasskarl, Neue Schliissel (1866) 128, 

 133, and are unquestionably correct.
