RUMPHIUS'S HERBARIUM AMBOINENSE 



or cuneate; lateral nerves 3 or 4 on each side of the midrib, 

 ascending, slender, obscure, sometimes nearly obsolete; petioles 

 about 8 mm long. Inflorescences axillary, solitary, about 2 cm 

 long, the flowers slender, about 2.4 cm long, cylindric, orange 

 below, yellowish above, 5- or mostly 6-merous, in racemosely 

 arranged triads, the rachis slender, the lateral branchlets bearing 

 the sessile flowers 2 to 4 mm long. Calyx cylindric-ovoid, 2 

 to 3 mm long, truncate, the subtending bracts broadly ovate, 

 rounded or obtuse, about 1.2 mm long, all the flowers sessile, 

 usually in threes, sometimes in pairs at the apex of each short 

 lateral branch. Petals free to the base, linear, about 1 mm wide, 

 the reflexed portion above the insertion of the filament linear, 

 6 to 7 mm long. Filaments 4 mm long, the anthers continuous, 

 linear, about 1.2 mm in length. Fruit narrowly ovoid, when 

 dry black and about 6 mm long. 



This species is possibly allied to Loranthus indicus Desr., but 

 it differs in many characters, notably in its smaller leaves, longer 

 petioles, and shorter, fewer-flowered inflorescences. The type 

 of Loranthus indicus Desr. was a specimen collected by Sonnerat 

 in "les Indies orientales," but de Candolle, Prodr. 4 (1830) 305, 

 credits it to Timor. Miquel, Fl. Ind. Bat. I 1 (1856) 820, thought 

 that Viscum amboinicum album Rumph. represented a species 

 of Dendrophthoe (Loranthus) near D. indica (Desr.) Miq. or 

 D. incarnata (Jack) Miq., but the Rumphian species is no 

 Dendrophthoe, as indicated by its entirely free petals. 



Viscum amboinicum III Rumph. Herb. Amb. 5 : 62, very briefly 

 described, is undoubtedly a species of Loranthus, but its status 

 cannot be definitely determined from any data at present avail- 

 able. Hasskarl, Neue Schliissel (1866) 95, thought it might 

 be the same as Macrosolen macrophyllus Miq. (Loranthus ma- 

 crophyllus Korth.), but this is entirely improbable, as that 

 species is known only from Sumatra.
