PERROTTETI A Humbolt, Bonpland, and Kunth 



PERROTTETIA MOLUCCANA (Blume) Loesen. in Engl. & Prantl. Nat. 

 Pflanzenfam. 3 5 (1892) 220. 

 Caryospermum moluccanum Blume Mus. Bot. 1 (1850) 176. 

 Vertifolia rubra Rumph. Herb. Amb. 3: 100, t. 67. 

 Amboina, Hitoe messen, Mahija, and Lateri, Robinson PL Rumph. Amb. 

 157, 160, 601, August and November, 1913, in forests, altitude 100 to 250 

 meters. 



No previous reduction of Vertifolia rubra Rumph. has been 

 suggested other than Hasskarl's tentative reference of it to the 

 Euphorbiaceae. The specimens cited above agree perfectly with 

 the description and very well with the figure, the fault in the 

 figure being that the flowers are relatively greatly enlarged. 

 Hasskarl was uncertain to which description, Vertifolia alba or 

 Vertifolia rubra, the figure pertained, as Rumphius does not 

 indicate which one he intended it for. The descriptions pertain 

 to two entirely different plants, of different genera, and probably 

 of different families. The Amboina material shows definitely 

 that the figure belongs with Vertifolia rubra Rumph. It is of 

 interest to note that the species is the type of the genus Caryo- 

 spermum and that Blume's material was from Amboina. 



ICACINACEAE 



CARDIOPTERYX Wallich 

 CARDIOPTERYX MOLUCCANA Blume Rumphia 3 (1847) 207. 

 Olus sanguinis Rumph. Herb. Amb. 5: 482, t. 180. 



This is not represented in our Amboina collections. Olus 

 sanguinis Rumph. was originally reduced by Linnaeus, through 

 error, to Dioscorea sativa Linn., in Stickman Herb. Amb. (1754) 

 25, Amoen. Acad. 4 (1759) 133, in which he was followed by a 

 number of authors. It has also been referred to Dioscorea clif- 

 fortiana Lam. and to D. deltoidea Wall. Blume placed it in 

 Cardiopteryx (often spelled Cardiopteris) in the original descrip- 

 tion of Cardiopteryx moluecana Rlume, which is manifestly the 

 correct disposition of it. 



STEMONURUS Blume 



STEMONURUS sp. 



Fructus bobae Rumph. Herb. Amb. 3: 166, 1. 105. 



Nothing resembling this form is represented in our Amboina 

 collections. The figure is an excellent one and presents an icacin- 

 aceous plant, undoubtedly of the genus Stemonurus. Teysmann, 

 quoted by Hasskarl, Neue Schliissel (1866) 62, placed it in Platea, 

 another genus of the same family.
