240 RUMPHIUS'S HERBARIUM AMBOINENSE 



CRUCIFERAE 



NASTURTIUM * R. Brown 



NASTURTIUM INDICUM (Linn.) DC. Syst. 2 (1821) 199. 



Sisymbrium indicum Linn. Mant. 1 (1767) 93. 



Sinapi indigenum s. amboinicum Rumph. Herb. Amb. 5: 282. 



Amboina, near the town of Amboina, Robinson PL Rumph. Amb. 268, 

 July 19, 1913, in and near ditches. 



Hasskarl, Neue Schlussel (1866) 121, has suggested that this 

 is a species of Sinapis; but from Rumphius's brief description, 

 the indicated habitat, and the note that it has no economic use, 

 it is evident that Nasturtium is the plant intended. 



BRASSICA (Tourn.) Linnaeus 



BRASSICA JUNCEA (Linn.) Coss. in Bull. Soc. Bot. France 6 (1859) 609. 



Sinapis juncea Linn. Sp. PI. (1753) 668. 

 Sinapi sinense Rumph. Herb. Amb. 5: 282. 



Amboina, Titauuku, Robinson PL Rumph. Amb. J+05, October 8, 1913, 

 in cleared places, altitude about 120 meters, locally known as susawi 

 ambon and rumput china blanda. 



This specimen I take to be typical Brassica juncea Coss., the 

 ordinary form that is widely distributed in the Malay Archipel- 

 ago. The plant, or plants, actually described by Rumphius, are, 

 however, the cultivated forms of Chinese origin, which appear 

 to be forms of Brassica pekinensis (Lour.) Skeels (Sinapis 

 pekinensis Lour.). Rumphius indicates two forms, under the 

 names album and nigrum. It seems very probable that this 

 commonly cultivated Chinese form is but a horticultural variety 

 of Brassica juncea Coss. 



CAPPARIDACEAE 



POLANISIA Rafinesque 



POLANISIA VISCOSA (Linn.) DC. Prodr. 1 (1824) 242. 



Cleome viscosa Linn. Sp. PI. (1753) 672. 

 Lagansa alba Rumph. Herb. Amb. 5 : 280, t. 96, f. 3. 

 Amboina, Liang, Robinson PL Rumph. Amb. U12, November 29, 1913, 

 along roadsides, at low altitudes, locally known as lagansa. 



This common weed was originally reduced by Linnaeus, in 



* Retained name, Brussels Congress; Cardaminium Moench (1794), and 

 Baeumerta Gaertn. (1800) are older.
