RUMPHIUS'S HERBARIUM AMBOINENSE 



I N DIGOFERA Linnaeus 



I N DIGOFERA T! NCTORI A Linn. Sp. PI. (1753) 751. 



Indicum Rumph. Herb. Amb. 5: 220, quoad descr. (excl. t. 80—1. 



suffruticosa Mill.). 



Probably both Indigo f era tinctoria Linn, and L suffruticosa 

 Mill. (I. anil Linn.) are included in the Rump hi an discussion of 

 Indicum, but the description of the pods as "digiti articulum 

 longae" applies unmistakably to Indigofera tinctoria Linn., not 

 to /. suffruticosa Mill. The figure, however, unmistakably repre- 

 sents Indigofera suffruticosa Mill., as shown by the relatively 

 short, strongly curved pods. Indicum was reduced by Linnaeus 

 to Indigofera tinctoria Linn., in Stickman Herb. Amb. (1754) 

 21, Amoen. Acad. 4 (1759) 130, Syst. ed. 10 (1759) 1171, Sp. 

 PL ed. 2 (1763) 1061, in which he has been followed by most 

 authors. Lamarck, Encycl. 3 (1789) 244, referred it to Indigo- 

 fera anil Linn.=7. suffruticosa Mill., which is the correct disposi- 

 tion of the figure. Other authors have referred it to Indigofera 

 anil Linn. var. orthocarpa DC, /. tinctoria Linn. var. macrocarpa 

 DC, and /. tinctoria Linn. var. brachycarpa DC 



INDIGOFERA SUFFRUTICOSA Mill. Gard. Diet. ed. 8 (1768) no. 2. 

 Indigofera anil Linn. Mant. 2 (1771) 272. 

 indicum Rumph. Herb. Amb. 5: quoad t, 80. 

 Amboina, near the town of Amboina, Robinson PI. Rumph. Amb. 195, 

 August 8, 1913, near the seashore. 



This is the form figured by Rumphius, but so far as the 

 description, goes the essential characters by which Indigofera 

 tinctoria Linn, and /. suffruticosa Mill, are distinguished are 

 those of the former species. As indicated above probably both 

 are included in the general discussion of Indicum. 



The several forms briefly described under Indicum I consider 

 to be indeterminable, although Hasskarl, Neue Schliissel (1866) 

 113, indicates their possible positions as follows : Indicum silvestre 

 Rumph. Herb. Amb. 5: 222=Indigofera sp.?; Indicum silvestre e 

 Madagascar Rumph. 1. c. 22S=Indigofera linifolia Retz. var. an- 

 gustissima Miq.?; Indicum brasilianum Rumph. 1. c. 22A=Indigo- 

 fera sp.?; Indicum spurium Rumph. 1. c. 224= Indigofera celebica 

 Miq.?. 



TEPHROSIA* Persoon 

 TEPHROSIA sp. aff. T. purpurea Pers. 



Phaseolus montanus I Rumph. Herb. Amb. 6: 146. 



No representative of the genus Tephrosia occurs in our Am- 

 boina collections. The plant described by Rumphius, however, 



* Retained name, Vienna Code; Cracca Linn. (1763) is older.
