RUMPHIUS'S HERBARIUM AMBOINENSE 



the above disposition of Rumphius's Calamagrostis is suggested 

 as its probable true position. Linnaeus, Sp. PL ed. 2 (1762) 65, 

 referred it to his Schoenus lithospermus=Scleria lithosperma 

 Sw., in which he was followed by Burman f., Fl. Ind. (1768) 

 19. Willdenow, however, Sp. PL 4 (1805) 315, referred it to 

 Scleria tessellata Willd., in which he has been followed by several 

 other authors. The plant, as described by Rumphius, has 

 nothing to do with Scleria, but is manifestly a coarse grass, and 

 it is certainly Anthistiria gigantea Hack., as suggested above. 

 The figure is very poor. 



DIGITARI A Scopoli 



DIGITARIA SANGUINALIS (Linn.) Scop. Fl. Cam. ed. 2, 1 (1772) 



52, var. 



Panicum sanguinale Linn. Sp. PI. (1753) 57. 

 Gramen caninum Rumph. Herb. Amb. 6: 11. 

 Gramen supplex Rumph. 1. c. 12? 

 Amboina, in sago swamp near the town of Amboina, Robinson PL Rumph. 

 Amb. 50, August 20, 1913. 



This is apparently Gramen caninum Rumph., described as 

 having two spikes. Gramen supplex Rumph. is described as 

 having three or four spikes. Both appear to be merely forms 

 of the polymorphous Digitaria sanguinalis (Linn.) Scop. 



PANICUM Linnaeus 



PANICUM REPTANS Linn. Syst. ed. 10 (1759) 870. 

 Panicum prostratum Lam. 111. 1 (1791) 171. 

 Gramen anatum Rumph. Herb. Amb. 6: 13. 

 Boeton, Rel. Robins. 2496, July 13, 1913; not represented in the Am- 

 boina collection. 



In this reduction of Gramen anatum I follow Hasskarl's sug- 

 gestion, who refers it with doubt to Panicum prostratum Lam. I 

 can see no reason for considering the Rumphian plant other 

 than this species ; the Linnean name is, however, the older. 



PANICUM STAGNINUM Retz. Obs. 4 (1786) 17. 



Champeu s. Campee, Rumph. Herb. Amb. 6: 11. 



The description is very brief, but probably Panicum stagni- 

 num Retz. is the form intended. Hasskarl has suggested Pani- 

 cum limnaeum Steud., but this is very improbable, P. limnaeum 

 Steud. being reduced in Index Kewensis to Panicum molle Sw. 

 The material considered by Rumphius was from Batavia, Java. 

 Koorders, Exkurs. Fl. Java 1 (1911) 129, gives tjampea as the 

 Sundanese name for Panicum stagninum Retz.
