RUMPHIUS'S HERBARIUM AMBOINENSE 



the Sapotaceae, while Henschel, Vita Rumph. (1833) 152, thought 

 that it might be Cambogia gutta Linn. The species is known 

 only from Amboina.

Ichthyoctonos litorea Rumph. Herb. Amb. 3: 213, t. 138. 



This species is not represented in our Amboina collections, 

 but I reduce the Rumphian species to Sapium indicum Willd. 

 with great confidence that this is the correct disposition of it. 

 Baillon, Etud. Gen. Euphorb. (1858) 518, suggested that it 

 was a Stillingia; while Hasskarl, Neue Schlussel (1866) 68, 

 reduced it to Excoecaria virgata Zoll. & Mor. =Sapium virgatum 

 Hook, f., a species very closely allied to Sapium indicum Willd. 

 Sapium virgatum Hook. f. is confined to Java, according to 

 Pax & K. Hoffmann, in Engl. Pflanzenreich 52 (1912) 250, while 

 Sapium indicum Willd. extends from India to New Guinea. The 

 figure given by Rumphius is fairly good, while the description 

 applies to Sapium indicum Willd. in all respects.

 Amboina, Hitoe lama, Robinson PI. Rumph. Amb. 352, October 8, 1913, 

 in cultivated ground, altitude about 150 meters; also represented by Rel. 

 Robins. 2497, from Boeton Island, July 13, 1913. 



Esula esculenta Rumph. was first reduced by Linnaeus to 

 Euphorbia hirta Linn., in Stickman Herb. Amb. (1754) 26, 

 Amoen. Acad. 4 (1759) 134, Syst. ed. 10 (1759) 1048, Sp. PL 

 ed. 2 (1762) 651, which is certainly the correct disposition of 

 it, and in which he was followed by many authors. In recent 

 literature the species appears chiefly as Euphorbia pilulifera 

 Linn., which is a synonym of Euphorbia hirta Linn., the latter 

 having page priority. Lamarck referred it, with doubt, to 

 Euphorbia capitata Lam., a synonym of Euphorbia hirta Linn.
