specific name is that supplied by the Linnean binomial, which is 

 here accepted in place of the almost universally used Cajanus 

 indicus Spreng. 



PHASEOLUS Linnaeus 



PHASEOLUS VULGARIS Linn. Sp. PL (1753) 723. 

 Phaseolus scriptus Rumph. Herb. Amb. 5: 382? 

 Faba rubra Rumph. Herb. Amb. 5: 382? 



Both of the above plants, very briefly described by Rumphius, 

 were exotics, which had been introduced into Amboina and 

 cultivated. Both of them may possibly be forms of Phaseolus 

 vulgaris Linn., but this disposition of them is a mere guess. 



PHASEOLUS AUREUS Roxb. Hort. Beng. (1814) 55, nomen nudum, Fl. 

 Ind. ed. 2, 3 (1832) 297. 

 Phaseolus mungo auctt., non Linn. 

 Phaseolus radiatus auctt., non Linn. 



Phaseolus minimus Rumph. Herb. Amb. 5: 386, t. 139, f. 2. 



The commonly cultivated and well-known mung bean is not 

 represented in our Amboina collections. Linnaeus originally 

 reduced Phaseolus minimus Rumph. to P. radiatus Linn., in 

 Stickman Herb. Amb. (1754) 23, Amoen. Acad. 4 (1759) 132, 

 Syst. ed. 10 (1759) 1162, in which he has been followed by all 

 authors who have had occasion to cite the Rumphian figure and 

 description. However, Phaseolus radiatus Linn, is not the mung 

 bean, but is the form described by Roxburgh as Phaseolus sub- 

 lobatus Roxb. Phaseolus max Linn., also referred to the mung 

 by some authors, is the soy bean, Glycine max (Linn.) Merr. 

 (Soja max Piper, Glycine hispida Maxim.) ; see page 274. 

 Phaseolus mungo Linn, is a species distinct from P. aureus 

 Roxb. (P. radiatus auctt.), the urd, or black gram, of India.* 



PHASEOLUS CALCARATUS Roxb. Hort. Beng. (1814) 54, nomen nudum, 

 Fl. Ind. ed. 2, 3 (1832) 289. 

 Phaseolus cylindraceus Rumph. Herb. Amb. 5: 389 ? 

 Amboina, Kati-kati, Robinson PL Rumph. Amb. 233, October 6, 1913, 

 in thickets, altitude about 90 meters. 



I am not sure that the plant here cited represents either 

 Phaseolus cylindraceus Rumph. or P. calcaratus Roxb. The 

 specimen is identical with the widely distributed, wild Philippine 

 form that I have referred to Phaseolus calcaratus Roxb.f, which 



* Piper, C. V. Five Oriental species of beans. U. S. Dept. Agr. Bull. 

 119 (1914) 1-32, t. 1-6, gives critical consideration of the mung bean and 

 its allies.
