RUMPHIUS'S HERBARIUM AMBOINENSE 



the original description of Sida hirta, but the actual type of the 

 species was a plant collected by Sonnerat. Linnaeus originally 

 considered the plate to represent a variety of Sida abutilon Linn., 

 in Stickman Herb. Amb. (1754) 15, Amoen. Acad. 4 (1759) 125; 

 while Burman f., Henschel, and Murray erroneously placed it 

 under Sida asiatica Linn. By other authors it has been placed 

 under Abutilon graveolens Wight & Arn. (Sida graveolens 

 Roxb.) , to which Abutilon hirtum has been reduced as a variety,* 

 but even if varietal forms be recognized, the specific name, 

 hirtum, being much older, should be retained. 



Abutilon litoreum Rumph. Herb. Amb. 4: 33, briefly described 

 in the same chapter with Abutilon laeve= Abutilon indicum 

 Sweet, was thought by Hasskarl, Neue Schlussel (1866) 73, 

 possibly to represent Abutilon albescens Miq. This suggested 

 reduction of Abutilon litoreum is possibly correct, but the definite 

 identification of the form described by Rumphius must await 

 further botanical exploration of the Moluccas. The plant is 

 undoubtedly an Abutilon and may be a form of A. indicum Sweet. 



SIDA Linnaeus 



SIDA ACUTA Burm. f. Fl. Ind. (1768) 147. 



Sida carpinifolia Linn. f. Suppl. (1781) 307. 

 Sida scoparia Lour. Fl. Cochinch. (1790) 414. 



Sigalurium II longifolium Rumph. Herb. Amb. 6: 45, t. 18, f. 2. 



Amboina, Lateri, Robinson PI. Rumph. Amb. 500, August 25, 1913, altitude 

 about 100 meters. 



The figure given by Rumphius is unmistakably Sida acuta 

 Burm. f., and Burman f. cites it in the original publication of 

 his species, although his description is based primarily on 

 actual specimens. Linnaeus erroneously referred it to Sida 

 spinosa Linn., in Stickman, Herb. Amb. (1754) 26, Amoen. 

 Acad. 4 (1759) 134, Syst. ed. 10 (1759) 1145. Loureiro, Fl. 

 Cochinch. (1790) 414, cites it as representing his Sida scoparia. 

 Most recent authors have followed Burman f ., which is certainly 

 the correct disposition of Sigalurium longifolium. 



SIDA RETUSA Linn. Sp. PL ed. 2 (1763) 961. * 



Sigalurium I rotundum s. vulgare Rumph. Herb. Amb. 6: 44, t. 19. 



This species is not represented in our Amboina collections. 

 The figure is unmistakably Sida retusa Linn., and it is cited in 

 the original description of that species, although it is not the 

 type. It was originally reduced by Linnaeus to Sida alnifolia 

 Linn., in Stickman Herb. Amb. (1754) 26, Amoen. Acad. 4 



* Masters in Hook. f. Fl. Brit. Ind. 1 (1874) 327.
