RUMPHIUS'S HERBARIUM AMBOINENSE 



(Dischidia collyris Wall.). Beccari, Malesia 2 (1886) 258, gives 

 a detailed description of Conchophyllum imbricatum Blume with 

 figures. 



HOYA R. Brown 



HOYA LUTEA Kostel. Algem. Med.-Pharm. Fl. 3 (1834) 1083 (type!). 



Hoya lutea Decne. in DC Prodr. 8 (1844) 635 (type!). 



Corona ariadnes lutea Rumph. Amb. 5: 465. 

 Amboina, Amahoesoe, Robinson PL Rumph. Amb. 82, August and Novem- 

 ber, 1913, on cliffs at low altitudes. 



The specimen cited above apparently represents Corona ariad- 

 nes lutea Rumph. which is the whole basis of both Hoya lutea 

 Kostel. and Hoya lutea Decne., Decaisne overlooking the fact that 

 Kosteletzky had already published the binomial. The specimen 

 has yellow flowers and differs from Hoya sussuela (Roxb.) 

 Merr. (Corona ariadnes punicea Rumph.) not only in its leaf 

 characters, but also in its different, very much smaller flowers, 

 which are but about 12 mm in diameter. 



HOYA RUM PHI I Blume Bijdr. (1826) 1065. 



Acanthostemma rumphii Blume Rumphia 4 (1848) 29, Mus. Bot. 1 

 (1849) 58. 



Nummularia lactea major I fusca Rumph. Herb. Amb. 5: 470, t. 



175, f. 1. 



Amboina, Lateri and Hitoe lama, Robinson PL Rumph. Amb. 3%, 605, 

 August and November, 1913, in forests, altitude 150 to 200 meters, locally 

 known as buah tali tali. 



Poiret, in Lamarck Encycl. Suppl. 1 (1810) 407, reduced the 

 Rumphian species with doubt to Apocynum agglomeratum Poir., 

 which was based on specimens from Santo Domingo, and to 

 which it certainly does not refer. Blume apparently based his 

 description of Hoya rumphii on Javan specimens, but in the 

 original description of the species reduced the Rumphian illustra- 

 tion as a synonym, which has been accepted by most subsequent 

 authors. The Amboina specimens may or may not be the same 

 as the Javan form. 



HOYA SUSSUELA (Roxb.) comb. nov. 



Asclepias sussuela Roxb. Hort. Beng. (1814) 20, nomen nudum, Fl.

 Hoya ariadna Decne. in DC. Prodr. 8 (1844) 635 (type?). 

 Corona ariadnes punicea Rumph. Herb. Amb. 5: 464, t. 172. 

 Amboina, Amahoesoe and Batoe merah River, Robinson PL Rumph. Amb. 

 90, August and September, 1913, on trees and rocks, sea level to 100 meters
