ISCHAEMUM Linnaeus 



ISCH AE M U M TIMORENSE Kunth Rev. Gram. 1 (1835) 369, t. 98. 



Hippogrostis amboinica I major Rumph. Herb. Amb. 6: 14, t. 5, f. 2? 

 Amboina, Batoe mera, along ditches, Robinson PL Rumph. Amb. U7, 

 July 20, 1913. 



This figure has been confused by some authors with Panicum 

 colonum Linn., and Hasskarl, Neue Schltissel (1866) 153, so 

 refers it. I am not quite certain that it is referable to Ischae- 

 mum timorense Kunth., but it surely is not Panicum colonum 

 Linn., although Hasskarl was apparently satisfied with this 

 reference of it. 



ANDROPOGON Linnaeus 



ANDROPOGON ACICULATUS Retz. Obs. 5 (1789) 22. 

 Rhaphis trivialis Lour. Fl. Cochinch. (1790) 553. 

 Gramen aciculatum Rumph. Herb. Amb. 6: 13, t. 5, f. 1. 

 Amboina, Amahoesoe, along roadsides, Robinson PL Rumph. Amb. £5, 

 August 13, 1913, locally known as rumput gintang. 



Linnaeus, Species Plantarum ed. 2 (1762) 84, erroneously 

 referred Gramen aciculatum to Panicum colonum Linn., but 

 while citing the name Gramen aciculatum he gives the figure 

 as t. 5, f. 3, which is apparently an Oplismenus. Loureiro cites 

 Gramen aciculatum in his description of Rhaphis trivialis, Fl. 

 Cochinch. (1790) 553; Willdenow, Sp. PL 1 (1797) 338, repeats 

 Linnaeus's error in referring it to Panicum colonum, citing the 

 Rumphian name, but t. 5, f. 3, as does Linnaeus, but later, op. cit. 

 4 2 (1805) 906, refers Gramen aciculatum t. 5, f. 1, to Andro- 

 pogon acicularis Willd.=A. aciculatus Retz. Rumphius's figure 

 is an excellent one. 



ANDROPOGON SORGHUM (Linn.) Brot. Fl. Lusit. (1804) 89, var. 

 Holcus sorghum Linn. Sp. PI. (1753) 1047. 



Sorghum s. Battari Rumph. Herb. Amb. 5: 194, t. 75 bis, fig. 1. 



This is not represented in our Amboina collections. The form 

 described and crudely figured by Rumphius is apparently the 

 one described by Linnaeus as Holcus saccharatus=Andropogon 

 sorghum var. saccharatus Hack. It was reduced to Holcus sac- 

 charatus by Linnaeus in Stickman Herb. Amb. (1754) 20, fol- 

 lowed in Amoen. Acad. 4 (1759) 130 (plate cited as 7U by error), 

 Syst. ed. 10 (1759) 1305, followed by Loureiro, FL Cochinch. 

 (1790) 645, and Willdenow, Sp. PL 4 2 (1805) 930. Burman f., 

 however, FL Ind. (1768) 220, refers it to Holcus sorghum Linn., 

 in which he is followed by Lamarck, Encycl. 3 (1789) 140. 

 Following Hackers classification, it is probably best placed under
