RUMPHIUS'S HERBARIUM AMBOINENSE 



ifolius Blanco to Macaranga mappa Muell.-Arg. as a synonym. 

 Pax and K. Hoffmann, in Engl. Pflanzenreich 63 (1914) 320, 

 assumed that Mueller was correct in his reduction of Blanco's 

 species, but drew up their description and prepared a figure 

 of Macaranga mappa wholly from Philippine material. The 

 Philippine material cited by these authors has nothing whatever 

 to do with the Amboina Macaranga mappa Muell.-Arg., which 

 is so entirely distinct from Macaranga grandifolia (Blanco) 

 Merr. that it must be placed in a different section of the genus. 

 In vegetative characters, in its staminate inflorescence, and espe- 

 cially in its pistillate inflorescence, Macaranga grandifolia 

 (Blanco) Merr. is totally different from Macaranga mappa 

 Muell.-Arg. The whole description and the figure given by 

 Pax and Hoffmann go with Macaranga grandifolia (Blanco) 

 Merr., together with the synonyms Macaranga porteana Andre, 

 Mappa porteana Wats., and Croton grandifolius Blanco. 



MACARANGA HISPIDA (Blume) Muell.-Arg'. in DC. Prodr. 15 2 (1866) 

 990. 



Mappa hispida Blume Bijdr. (1825) 624. 



Halecus rugosa Rumph. Herb. Amb. 3: 198. 

 Amboina, Mahija, Robinson PL Rumph. Amb. 363, 36k, August 12, 1913, 

 in light forest at an altitude of 250 meters, locally known as haleki and as 

 bilang kinar. 



No previous reduction of Halecus rugosa Rumph. has been 

 suggested. Rumphius's description agrees perfectly with the 

 specimens cited above, which are at the same time apparently 

 typical Macaranga hispida Muell.-Arg., which was originally 

 described by Blume from Moluccan specimens. The Philippine 

 material referred here is very much more pubescent than the 

 Amboina specimens. 



MACARANGA TANARIUS (Linn.) Muell.-Arg. in DC. Prodr. 15 2 (1866) 

 997. 



Ricinus tanarius Linn, in Stickman Herb. Amb. (1754) 14, Amoen. 

 Acad. 4 (1759) 125, Syst. ed. 10 (1759) 1277, Sp. PI. ed. 2 (1763) 

 1430 (type!). 

 Mappa tanarius Blume Bijdr. (1825) 624. 

 Ricinus mappa Roxb. Fl. Ind. ed. 2, 3 (1832) 690, non Linn. 

 Tanarius minor alba Rumph. Herb. Amb. 3: 190, t. 121. 

 Tanarius minor rubra Rumph. Herb. Amb. 3: 190. 

 Amboina, Hoenoet, Robinson PL Rumph. Amb. 362, October 18, 1913, in 

 wooded glens, altitude about 200 meters, locally known as hunua. 



The Rumphian figure and description are the whole basis of 

 Ricinus tanarius Linn, and are hence the type of the species. 

 Most early authors considered it under the Linnean binomial,
